SYNOPSIS
openssl pkcs7 [-help] [-inform DER|PEM] [-outform DER|PEM] [-in filename] [-out filename] [-print] [-print_certs] [-quiet] [-text] [-noout] {- $OpenSSL::safe::opt_engine_synopsis -}{- $OpenSSL::safe::opt_provider_synopsis -}
DESCRIPTION
This command processes PKCS#7 files. Note that it only understands PKCS#7 v 1.5 as specified in IETF RFC 2315. It cannot currently parse CMS as described in IETF RFC 2630.
OPTIONS
- -help
-
Print out a usage message.
- -inform DER|PEM, -outform DER|PEM
-
The input and formats; the default is PEM. See openssl-format-options(1) for details.
The data is a PKCS#7 Version 1.5 structure.
- -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 out the full PKCS7 object.
- -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.
- -quiet
-
When used with -print_certs, prints out just the PEM-encoded certificates without any other output.
- -text
-
Prints out certificate details in full rather than just subject and issuer names.
- -noout
-
Don't output the encoded version of the PKCS#7 structure (or certificates if -print_certs is set).
