Format .sig(from English Signature— signature) — a file containing an electronic digital signature. The digital signature is attached to an email or document. How to open SIG format files depends on the original extension. If you signed PDF or JPEG, you need graphic editors; if XML or DOC/DOCX, you need text editors.

Digital signature confirms the authenticity of a text document or raster image. The technology is used to confirm documents in Rosreestr and at the State Services port. This is where most users encounter the SIG format, or more precisely, the inability to open the file with familiar programs.

How to open .sig files:

SIG on Windows: Notepad, Outlook, Crypto Pro

The easiest way to open a text document with a signature is to use a standard notepad (Notepad). The method is not suitable for documents in image formats. In addition, not all text documents open correctly.

1. Notepad- standard Notebook, which is on every Windows computer. You can open the program via Start -> Standard -> Notebook, or simply by clicking on the file RMB -> To open with… and selecting notepad there. In the program you need to click on the menu File -> Open… and select the desired document on your computer. Both editing and saving text are available.
2. Microsoft Outlook And Microsoft Outlook Express— Usually the program is already available on Windows if a full suite of office applications has been installed. If not, Outlook can be installed separately by downloading from the website products.office.com free trial version of the application. There is a mobile version for iOS and Android.
3. CryptoPro— specialized software for working with digital signatures from a large Russian company. Many programs, scripts and libraries from CryptoPro are available for free download (www.cryptopro.ru/downloads) or purchase. To download files, registration on the official website may be required.
4. CryptoARM— specialized software for working with digital signatures, also from a Russian company (www.trusted.ru). For those who work with signatures and SIG extensions on an ongoing basis, it is recommended to purchase a CryptoARM license. The program has several dozen types of licenses, depending on the method of use and version of the program. For one-time opening of documents in .sig format, you can download free 14-day trial.

If a document with the SIG extension was created as a result of signing an email, it is better to open it in Outlook. If you just need to view the contents of a document, the capabilities of a standard notepad are sufficient. To seriously work with digital signatures, you need to choose between CryptoPRO and CryptoARM - there is a free trial period to decide.

SIG on MacOS: Eudora and Mozilla Thunderbird

The Internet recommends using the QUALCOMM Eudora e-mail client for MacOS. The latest version of the program is listed as Eudora 8, optimized for Mac OS X 10.4 and higher.

When you try to go to the developer’s website www.eudora.com, you are redirected to the website of the Computer History Museum. For those who really really need it, you can find the source code of the e-mail client in the article and try to install it.

1. Mozilla Thunderbird- first free and still supported a program suitable for working with sig files. This is a free, convenient and functional e-mail client that opens letters with digital signature. Mozilla Thunderbird is a cross-platform program that works correctly on almost any device, including various versions of MacOS.

In addition to these methods, documents can be viewed online on the Rosreestr website. It works well on the Mac's built-in Safari browser. If desired, you can use any other browser (Chrome, Yandex, Opera, Mozilla).

View online on the Rosreestr website

The Rosreestr website has a service that allows you to check electronic documents. It is possible to check the signature on two types of files: Digital signature ( sig files) and Electronic documents ( xml files).

Online verification of documents with digital signature is simple:

There are two ways to display a document:

• xml only. You can download and display only the contents of the xml file received from State Services or Rosreestr. In this case, the document will be displayed, but the signature will not be verified.
• Xml and sig. If you need to not only look at the file, but also check the authenticity of the signature, you need to upload both documents in both fields. As a result, it should be written that the verification was successful, and the xml file is certified with the digital signature of an authorized official. It will be indicated separately who signed the document.

The document will open in a new window, after which you can not only view the document, but also save it or send it to print.

If the document does not open in the browser:

• To work with the Rosreestr service, it is advisable to use Internet Explorer or Safari. You can use others, but you will have to set additional settings.
• IN Google Chrome required Load insecure script or set the loading of such scripts in the settings. You also need to go to Settings chrome://settings/content and enable JavaScript loading.
• In the browser Mozilla Firefox need to press Disable protection on this page, otherwise the browser will block the script.
• Google Chrome has the ability to save an open document in the format PDF. To do this in the settings Stamps browser you need to change the printer to option Save as PDF.

Documents can take a long time to open; working online with large files requires a high-speed Internet connection.

Broderbund Sign File Graphics Format

Much less often, SIG files contain not a digital signature, but raster graphics in the Broderbund Sign File format. The format is rarely used, since it is only reproduced by software products from the manufacturer Broderbund. The format is intended for the PrintMaster and The Print Shop programs, although it can also open in other Broderbund software (but this is not certain).

Very often, users ask what the *.sig file format is and can programs open it?

It should be noted right away that there may be several options here that are radically different.
The most common *.sig files are used as digital signatures, the so-called elements of cryptographic protection of documents used by email programs confirming that we have indeed received the document we need.
Otherwise it may not be a common graphics, raster file.

* .sig Files, as elements of cryptographic protection, digital signatures are mainly attached to an email, at the end of it as a separate file exclusively for email programs, which we do not see, or for programs that work with digital signatures when sending or receiving data.

In this case, they can be opened using the following programs. In the Windows operating system, Microsoft software products such as Outlook and Outlook Express. The QUALCOMM Eudora programs, CryptoARM - a specialized program for working with digital signatures, as well as its analogue Crypto Pro.

If *.sig is a graphic file then using programs that work with this type of graphics are Broderbund The Print Shop, as well as Broderbund Print Master.

The .sig extension is usually automatically attached to the end of an email. There may be the sender's email address and his name. Here is a list of applications with which to open the sig file.

Microsoft Outlook; Microsoft Outlook Express; QUALCOMM Eudora; CryptoARM; Crypto Pro;

You need to open the full letter/file in a client that understands this digital signature format in order to receive reliable user information (the message has not been changed, the signature has not expired, the signature belongs to such and such)

The full name of such a file is Signature File and it belongs to the category of text files.
This file contains a small amount of text, and this text is automatically attached to the end of the email itself.

There is also such an extension -Broderbund Sign File and it can be a raster image, and it can also be opened with a special program, but you can download it here.

When working in telegraph mode, shortwave radio amateurs report and communicate using different code abbreviations. The SIG code there stands for Signature. If we try to transfer the analogy to a file association, then we will have a certain shipment (parcel) that has a sender and a recipient. The sender must identify himself with an encrypted signature. Therefore, any email program can open a file with such a signature.
