DESCRIPTION
The ppkkccss77 command processes PKCS#7 files in DER or PEM format.
COMMAND OPTIONS
-
--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 certificates
-
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.
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.
