OPENSSL-PKCS7(1)

NAME
openssl-pkcs7 - PKCS#7 command

SYNOPSIS
openssl pkcs7 [-help] [-inform DER|PEM] [-outform DER|PEM] [-in filename] [-out filename] [-print] [-print_certs] [-quiet] [-text] [-noout] [-provider name] [-provider-path path] [-provparam [name:]key=value] [-propquery propq]

DESCRIPTION
This command processes PKCS#7 files. Note that it only understands PKCS#7 v 1.5 as specified in IETF RFC 2315. It cannot currently parse CMS as described in IETF RFC 2630.

OPTIONS

-help
    Print out a usage message.

-inform DER|PEM, -outform DER|PEM
    The input and formats; the default is PEM. See openssl-format-options(1) for details.

    The data is a PKCS#7 Version 1.5 structure.

-in filename
    This specifies the input filename to read from or standard input if this option is not specified.

-out filename
    Specifies the output filename to write to or standard output by default.

-print
    Print out the full PKCS7 object.

-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.

-quiet
    When used with -print_certs, prints out just the PEM-encoded certificates without any other output.

-text
    Prints out certificate details in full rather than just subject and issuer names.

-noout
    Don't output the encoded version of the PKCS#7 structure (or certificates if -print_certs is set).

-provider name
-provider-path path
-provparam [name:]key=value
-propquery propq
    See "Provider Options" in openssl(1), provider(7), and property(7).

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
