PKCS7(1)                            OpenSSL                           PKCS7(1)

N
       pkcs7 - PKCS#7 utility

S
       ooppeennssssll ppkkccss77 [--iinnffoorrmm PPEEMM||DDEERR] [--oouuttffoorrmm PPEEMM||DDEERR] [--iinn ffiilleennaammee] [--oouutt
       ffiilleennaammee] [--pprriinntt_cceerrttss] [--tteexxtt] [--nnoooouutt] [--eennggiinnee iidd]

D
       The ppkkccss77 command processes PKCS#7 files in DER or PEM format.

C
       --iinnffoorrmm DDEERR||PPEEMM
           This specifies the input format. DDEERR format is DER encoded PKCS#7
           v1.5 structure.PPEEMM (the default) is a base64 encoded version of the
           DER form with header and footer lines.

       --oouuttffoorrmm DDEERR||PPEEMM
           This specifies the output format, the options have the same meaning
           as the --iinnffoorrmm option.

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

       --oouutt ffiilleennaammee
           specifies the output filename to write to or standard output by
           default.

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

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

       --nnoooouutt
           don't output the encoded version of the PKCS#7 structure (or cer-
           tificates is --pprriinntt_cceerrttss is set).

       --eennggiinnee iidd
           specifying an engine (by it's unique iidd string) will cause rreeqq 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.

E
       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

N
       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-----

R
       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.
