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#7v1.5 structure.PEM (the default) is a base64 encoded version ofthe 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 thisoption is not specified.
- -out filename
- specifies the output filename to write to or standard output bydefault.
- -print_certs
- prints out any certificates or CRLs contained in the file. They arepreceded by their subject and issuer names in one line format.
- -text
- prints out certificates details in full rather than just subject andissuer names.
- -noout
- don't output the encoded version of the PKCS#7 structure (or certificatesis -print_certs is set).
- -engine id
- specifying an engine (by it's unique id string) will cause reqto attempt to obtain a functional reference to the specified engine,thus initialising it if needed. The engine will then be set as the defaultfor all available algorithms.
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
NOTES
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-----
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.
