Often, when stumbling upon the *.sig format, people wonder what it is. The second question that arises immediately after the first is: "How to open the sig extension?".
What is sig?
sig extension ( English signature - signature) is a file format Most often used in documentation sent via e-mail. For a simple user, this format may occur once or twice, but in a commercial environment it is not uncommon.
Despite the scary name and perhaps not entirely clear explanation, sig is a text file, just like txt or doc (docx). It contains information about the sender of the letter (usually the company name, sender's name, contacts, etc.), is edited by him (and therefore can also contain all sorts of quotes, advertising calls, and anything else) and is automatically attached to the letter.
extension?
Although most people associate mail with mail and gmail, those who, on duty, constantly intersect with it, use special software systems - mail programs. They are multifunctional and, among other things, open sig extensions. How to open a letter with a similar extension from such software? The most popular services are:
- Microsoft Outlook is part of an extended set of office suites from Microsoft.
- Eudopa is a common mail client in the West with an English-only interface. The advantage is that it works with both Windows and Apple MacOS.
- Mozilla ThunderBird, Opera Mail - development of mail programs from well-known browsers.
Which mail program to choose - a topic for a new article. If you are guided only by the criterion "how to open a sig extension", any, even the simplest mail client, will do.
Other programs
To create digital signatures, there is a program "CryptoARM" - with free and paid versions. Through it, *.sig files are opened and created. For encryption in "CryptoARM" standard Windows cryptographic providers are used, so it is easy and simple. The software has no advantages over the method described below for a simple layman, but it will be of interest to novice cryptographers.
If you do not want to install a new program
The good old "Notepad" comes to the rescue - with this program, if desired, you can even open a picture (although its text encoding is unlikely to be to anyone's taste), to say nothing of a *.sig text file.
How to open anything for free? Notepad, of course! So the digital signature files are opened through it, and created, and edited. In the last two cases, the main thing is not to forget to enter the name of the corresponding extension after the file name when saving.
Finally
Such a document is found in files containing an electronic (digital) signature. There is also an abbreviated name EDS. There are two ways to open a SIG file: on a computer and online services. From government agencies one structure most actively uses the SIG file - Rosreestr. How to open SIG, we will tell below.
General description of the SIG format
There are 4 types of such files (signatures):
- Digital, used in e-commerce, government, etc. It is used to confirm the authenticity of a document and is an analogue of a handwritten signature;
- Postal - a file containing the contact details of the sender;
- Graphic for visual materials;
- Braille files.
The name SIG comes from the abbreviation of the word "signature" - signature. Electronic or digital, it accompanies a document or letter, the contents of which need to be confirmed.
The idea of a digital signature appeared in the late 1970s in the United States. The algorithm for its creation was developed in 1977. Then the development teams came up with their own cryptographic encryption methods to protect the signature from forgery. The secure algorithm was developed in 1984. Legislatively in Russia, GOST on digital signature was adopted 10 years later, then updated in 2002 and 2013.
An electronic signature is inextricably linked with the concept of hashing. A hash function is a mathematical algorithm that converts an arbitrary amount of data into a string of 40 characters. For example, when hashing the title of this article with the MD5 algorithm, the result is a string:
B4567551CF19AB29115096CC5A2B72C9
When hashing the number "1" by the same algorithm, it turns out:
C4CA4238A0B923820DCC509A6F75849B
If the content of the information has changed during the transfer, then the hash will change too. When comparing the start and end hashes, the changes in the document will be detected.
An electronic signature is a private key belonging to its owner, a certificate of conformity, which the owner receives in a specialized center. He confirms that the signature belongs to this person. Having received the file, the recipient's program hashes the data again and compares the received hash with the encrypted hash from the digital signature. If the hashes match, the document is valid.
How and with what to open the SIG file extension
Depends on file type. If a file of this extension was sent as an attachment to an e-mail, then it contains information about the sender, contact details, name, sometimes position and name of the department. In this case, the files are opened by mail services. On windows it is:
- - Simplified mail service Microsoft;
- - mail client with the ability to send text and voice messages;
- Microsoft Outlook 2016 is a corporate paid mail service with the possibility of sharing and a common contact database.
How to open SIG format on Mac OS:
Another type of SIG is Broderbund software product files. This is a type of digital signature that is used for graphic images produced by the company's programs. Labels on posters and banners are just an extension of SIG. How to open:
- The Print Shop
- The Print View
- Print Master
Open SIG file online
You can open the SIG file online or check the authenticity of the electronic signature on the Rosreestr website. To do this, you need two files: XML and SIG. In the electronic signature verification window, there is an "open" button. When pressed, the address bar or explorer opens, in which you must specify the location of the files. On the State Services portal, you can also work with SIG, open it online and get a cadastral extract. In addition, SIG is converted to pdf by the web service ru.pdf24.org.
On the computer
Before opening the SIG file on a PC, you will have to install additional software for working with digital signatures. Such programs are paid, but they have a trial period of thirty days, for which you do not have to pay. SIG open:
- CryptoARM is a domestic cryptographic company that produces software and issues signature and identity certificates;
- Crypto Pro is a competing series of cryptographic programs developed by the company of the same name and distributed throughout the Russian Federation. They also have a network of centers that issue certificates of conformity (both accredited according to the Federal Law and without accreditation).
A SIG (Signature File) file is a small text file type that can be automatically attached to the end of email messages. Quite often, the SIG format can contain sender names as well as e-mail addresses of various users. This file extension will contain the digital signature of its owner, and may store the sender's contact information, name and telephone contacts. Among the active users of this file format, there are lovers to add all kinds of quotes and so on to the signed file.
The .sig file is quite common in the field of email. To open a file that has the SIG extension, use such software systems as Microsoft Outlook and QUALCOMM Eudora. Such utilities can not only open the SIG file, but also edit it, as well as generate the .sig extension. The presence of the proper software contributes to the subsequent comfortable work with the electronic box and makes it possible to open SIG files. It is worth noting that the Eudora application is optimized to work with both Windows and Mac OS.
Often, short welcome messages are placed in the contents of SIG files. AT modern world world wide web, electronic signature the owner is an indicator of his status and solidity, so the .sig extension has quite extensive application indicators.
In order to open a .sig file, you must follow the usual scheme for launching files on a computer, the main thing is to have a correctly configured program that can open and edit a SIG file.
A feature of the extract from Rosreestr in in electronic format is to provide it in an xml form that is inconvenient for reading.

What is the document, what information does it contain, what are the ways to obtain information from the programming version and what to do if the graphic plan is not visible in the cadastral passport. detailed instructions with examples.
What it is
From January 1, 2020, all information contained in the state register of rights to real estate and the cadastre were merged into a single USRN database. It contains information:
- data from cadastral passports, drawings, coordinates of land plots;
- cadastral number of the premises or land allotment;
- the area of the site, its boundaries, their designation on the ground, if surveying has been carried out, permitted use;
- the layout of the premises, its purpose - residential or commercial, the size of its structural elements;
- cadastral value of real estate, close to the market value;
- date of putting the object on cadastral registration;
- the history of the transfer of rights to objects - the full name of the owners, title documents: contracts of sale, exchange, donation, inheritance, privatization, order of a state or municipal authority, etc.
How to get it
There are many ways to issue an extract from the USRN. You can personally contact the departments of Rosreestr or the MFC, or order a document through the Russian Post in the original or use the services online.
Information available upon request:
- through offsite Rosreestr;
- using the commercial portal Ktotam.pro;
- through a single resource of the State Service.
A request is sent by filling out a special form. To do this, you need to know the exact address of the property or its cadastral passport. If this information is unknown, then you can get it online for free through the Public Cadastral Map of Russia service.
Information is reflected on a single portal in automatic mode when marking the location of an apartment building, an individual building object or a land plot on a cartographic area.
An extract is required in the following cases:
- plans to acquire certain housing or land for building or farming;
- when concluding a preliminary sale and purchase agreement with a deposit to obtain information about the owner;
- in case of land disputes - to draw up an act of land surveying;
- consideration of a case in court in relation to an apartment or premises for entrepreneurial activity, including in inheritance disputes, in connection with donation, disposal of the object of joint property of spouses, etc.;
- checking property for the presence of encumbrances when depositing as a pledge or mortgage to a bank;
- determination of the debtor's property in the framework of enforcement proceedings in the collection of payments and other circumstances.
To receive a service through the State Register, you must register on a single portal and identify the user. Then go to the "Electronic Services" section and select the "Extract from the USRN" item.
The system will automatically redirect to the website of Rosreestr, where an application is filled out, data on the person who applied for the public service, the address or cadastral number of the property.
If the exact location of the object or its cadastral number is unknown, then you can use the Public Map of Rosreestr.
On it, it is enough to enter the region and district where the property is located, indicate the approximate location on the cartographic map, or find it by nearby houses or plots.
Information about the object will appear automatically. The service is provided free of charge, no request is required, all parameters are displayed immediately on the screen online if there is an Internet connection.
How to open the xml file of the USRN statement from Rosreestr
The algorithm for opening an encoded file is as follows:
- Upon receipt of a response from Rosreestr, it is necessary to upload the electronic archive to a folder. The name does not need to be changed, but the inscription.sig needs to be translated into a folder (1). It reflects the graphic plan for the apartment and its mark on the floor plan of the house.
- Next, you should go to a special page on the Rosreestr website https://rosreestr.ru/wps/portal/cc_vizualisation, designed to open files of this type.
- Then you need to click on the link "Choose a file" and upload an electronic document in xml format.
- After that, you need to click "Digital Record" (sig file) on the document in the folder.
- By clicking the "Checks" button, you should go to the "Show in human form" section.
- After that, the statement will open in the browser in the html format that can be viewed on any program. In order to use the document later, you need to click "Save" or you can immediately print the certificate. If there are no corresponding buttons, you can type the combination of numbers CTRL + C, for printing - CTRL + P.
If the graphic plan is not displayed
Sometimes, when retrieving a document, it is not possible to read the schema of an object. The folder contains a document with the entry "There is no graphic plan of the room."
In order for it to become readable, you need to move this document to a folder with an open html file. At the same time, you cannot rename the graphic plan; it must remain unchanged.
Now, when opening an html document, the layout of the object is visible. It can be saved or printed immediately.
Difficulties arise with the opening of an extract from the cadastral passport. They are also provided in xml form. and xml.sig.
In order to view the layout plan of the object and basic information about it, you need to use the same methods as when opening an extract from the USRN, as now the information is contained in one database.
Online
There are other ways to open an electronic extract from Rosreestr. To do this, you can use any common browser such as:
- Safari;
- Internet Explorer;
- Google Chrome;
- Opera;
- Mozilla Firefox.
An example of opening an xml file in Internet Explorer:
- open browser. In the top panel, open the "Tools", the tab "Compatibility View Options";
- in the box that opens, check the box "Display all websites with compatibility mode";
- press alt, in the menu that opens, open "Tools", "Internet Options". On the "Security" tab, select "Trusted Sites";
- then click "All nodes in the zone require https server verification". In the form that opens, using the "Add" button, enter the addresses: https://*.rosreestr.ru and http://*.arcgisonline.com/;
- Without leaving this window, you need to switch the "Advanced" mode. In all lines, select "Allow".
The checkmarks from the enabled protected mode are removed.
An alternative to obtaining a statement immediately in html mode, which does not need to be opened using software, is to order a document on the commercial website Ktotam.pro. Information on the application on it is requested officially from the real estate database of Rosreestr.
In addition, the advantage of using the server is the urgency of receiving an answer to e-mail and the relatively low cost of receiving the service - 300 rubles. With individuals and 650 rubles. from legal. There are no fees for mediation.
It's important to know that electronic version the extract is informative and is not accepted as an official document by municipal and state authorities, does not serve as evidence in court.
And what problems only do not have to solve computer programmers in their activities. Here is one of the puzzles. It seems like you just need to open the file and that's it ...
However, in practice, everything is not at all simple. Trying to open an understandable XML file, we get a blank page. We climb into the code - everything seems to be logical - a bunch of data in XML tags. We understand that the problem is that there are no design settings in the file itself. They must be loaded from an external resource... And the specified file also refers to a group of files with settings for each section of the document. As a result, all browsers refuse to load all these files, seeing this as a gross violation of the security policy.
And here the "dancing with a tambourine" begins: we turn off "protection from dangerous sites" in the browser settings; we start the browser with disabled security tools; looking for additional services; invent and write additional programs. The first time I encountered this problem, running Firefox browser with options to disable protection. As it turned out, this decision was enough for about a year. And suddenly this method stopped working. And on different computers and in different versions of browsers.
To solve this problem once and for all, I had to study this issue in more detail. It turns out that the solution to the problem is available on the Rosreestr website itself. And there is even an instruction there (only, at the time of writing this article, it was outdated - the design of the site has changed, and nothing can be done according to the pictures in this instruction).
I will no longer torment thoughts and memories.
Solution
1. Go to the "Checking an electronic document" page on the Rosreestr website.
2. There is a field on this page. This is the field for specifying your file to upload. We press the button "Review…"(The name may be different in different browsers). Select the desired XML file on your computer.
3. Having specified the required file, at the bottom of the form, press the button "Check>>".
4. When the page refreshes, next to the field "Electronic document (xml-file)" information about the downloaded file will appear, and next to it it will be written "Show in human readable format". By clicking on this link, you will open a new window in which your file will be in an understandable form.
