NAME¶

SYNOPSIS¶

DESCRIPTION¶

OPTIONS¶

-help

Print out a usage message.

-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 and default 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).

-engine id

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.

EXAMPLES¶

 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

NOTES¶

 -----BEGIN PKCS7-----
 -----END PKCS7-----

For compatibility with some CAs it will also accept:

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

RESTRICTIONS¶

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.
