openssl pkcs7

PKCS#7 utility 

openssl command


SYNOPSIS

openssl pkcs7 [-help] [-inform PEM|DER] [-outform PEM|DER] [-in filename] [-out filename] [-print_certs] [-text] [-noout] [-engine id]


DESCRIPTION

The pkcs7 command processes PKCS#7 files in DER or PEM format.

Options

-help 

Print out a usage message.

-inform DER|PEM 

specifies the input format. DER format is DER encoded PKCS#7 v1.5 structure.PEM (the default) is a base64 encoded version of the DER form with header and footer lines.

-outform DER|PEM 

specifies the output format, the options have the same meaning and default as the -inform option.

-in filename 

specifies the input file name to read from or standard input if this option is not specified.

-out filename 

specifies the output file name to write to or standard output by default.

-print_certs 

prints out any certificates or CRLs contained in the file. They are preceded by their subject and issuer names in one line format.

-text 

prints out certificates details in full rather than just subject and issuer names.

-noout 

does not output the encoded version of the PKCS#7 structure (or certificates is -print_certs is set).

-engine id 

specifying an engine (by its unique id string) will cause pkcs7 to attempt to obtain a functional reference to the specified engine, thus initialising it if needed. The engine will then be set as the default for all available algorithms.


EXAMPLES

Convert a PKCS#7 file from PEM to DER:

openssl pkcs7 -in file.pem -outform DER -out file.der

Output all certificates in a file:

openssl pkcs7 -in file.pem -print_certs -out certs.pem

NOTES

The PEM PKCS#7 format uses the header and footer lines:

-----BEGIN PKCS7-----
-----END PKCS7-----

For compatability with some CAs it will also accept:

-----BEGIN CERTIFICATE-----
-----END CERTIFICATE-----

RESTRICTIONS

There is no option to print out all the fields of a PKCS#7 file.

This PKCS#7 routines only understand PKCS#7 v 1.5 as specified in RFC2315 they cannot currently parse, for example, the new CMS as described in RFC2630.
