pkcs7 - PKCS#7 utility


SYNOPSIS

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


DESCRIPTION

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


COMMAND OPTIONS

       -inform DER|PEM
           This 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
           This specifies the output format, the options have the
           same meaning as the -inform option.

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


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

       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.
