Document formats
The following sets out an explanation of the file
formats which can be retrieved in the register portal, as well as assistance in searching for a display program on the internet if no suitable program is installed on your computer. In general you can also find programs for all current file formats which you can download and use free of charge.
Due to competition laws we are not permitted to offer
any concrete product recommendations regarding the latter.

pkcs7, p7m, p7s (file formats with embedded signature)
The contents of files in "pkcs7", "p7m", "p7s" file formats are encrypted and can only be displayed with appropriate signature programs.
PKCS (Public Key Cryptography Standards)
Described in RFC 2315. Forms the basis for S/MIME and is used to sign or encrypt PKI messages. RFC 2315 has been superseded by RFC 3852. In the meantime RFC 5652 is the prevailing version.
Here are the following file extensions for PKCS#7:
S-TRUST Sign-it Software saves data in various file
formats. You can set the format in the S-TRUST Sign-it Security Environment Manager. When installing the software the format is set by default in such a way that the signature file and the original data are saved in one file.
If you do not have a program that allows you to open such files you can use your chosen browser search engine to find suitable programs with the following search terms:
Open download software pkcs7
p7s format
p7s files are PKCS#7 data: they use a detached
signature. This means that the signed data and the signature are saved in two separate files. This has the advantage that it is possible to view the original data with the associated program. As long as this is not changed the signature also remains valid. The signature is linked to the original file by the same file name. If you open a p7s file by double clicking on it the signature check starts automatically.
If you do not have a program that allows you to open such files you can use your chosen browser search engine to find suitable programs with the following search terms:
Open download software p7s
p7m-Format
p7m files are PKCS#7 data: signed, encrypted or
signed and encrypted data may be concealed. Signed or signed and encrypted p7m files exist as composite files. This means that the files contain both one or more signatures in p7s format as well as the original data which was signed or signed and encrypted. If you double-click on a p7m file the file, if encrypted, is decrypted. Finally the signature test, if a signature is present, is started.
If you do not have a program that allows you to open such files you can use your chosen browser search engine to find suitable programs with the following search terms:
Open download software p7m
odt (Open Document-Text)
