openssl-pkcs7, pkcs7 - PKCS#7 utility
openssl pkcs7 [-help] [-inform PEM|DER] [-outform PEM|DER] [-in
filename] [-out filename] [-print_certs] [-text] [-noout] [-engine id]
The pkcs7 command processes PKCS#7 files in DER or PEM format.
Print out a usage message.
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.
This specifies the output format, the options have the same meaning
and default as the -inform option.
This specifies the input filename to read from or standard input if
this option is not specified.
Specifies the output filename to write to or standard output by
Prints out any certificates or CRLs contained in the file. They are
preceded by their subject and issuer names in one line format.
Prints out certificates details in full rather than just subject
and issuer names.
Don't output the encoded version of the PKCS#7 structure (or
certificates is -print_certs is set).
Specifying an engine (by its unique id string) will cause pkcs7 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.
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:
For compatibility with some CAs it will also accept:
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.
