PKCS7(1)                            OpenSSL                           PKCS7(1)

       pkcs7 - PKCS#7 utility

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

       The pkcs7 command processes PKCS#7 files in(1,8) DER or PEM format.

       -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(1,3,5) 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(2,n,1 builtins) from or standard input if(3,n)
           this option is not specified.

       -out filename
           specifies the output filename to write(1,2) to or standard output by

           prints out any certificates or CRLs contained in(1,8) the file. They are
           preceded by their subject and issuer names in(1,8) one line format.

           prints out certificates details in(1,8) full rather than just subject
           and issuer names.

           don't output the encoded version(1,3,5) of the PKCS#7 structure (or cer-
           tificates is -print_certs is set(7,n,1 builtins)).

       -engine id
           specifying an engine (by it's unique id string(3,n)) will cause req to
           attempt to obtain a functional reference to the specified engine,
           thus initialising it if(3,n) needed. The engine will then be set(7,n,1 builtins) as the
           default for all available algorithms.

       Convert a PKCS#7 file(1,n) from PEM to DER:

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

       Output all certificates in(1,8) 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 compatibility with some CAs it will also accept:

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

       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(1,8)
       RFC2315 they cannot currently parse, for example, the new CMS as
       described in(1,8) RFC2630.
