     NAME
          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

     PKCS7(1)               0.9.6h (2000-02-22)               PKCS7(1)

     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.
