crl2pkcs7 - Create a PKCS#7 structure from a CRL and
certificates.
SYNOPSIS
openssl pkcs7 [-inform PEM|DER] [-outform PEM|DER] [-in
filename] [-out filename] [-print_certs]
DESCRIPTION
The crl2pkcs7 command takes an optional CRL and one or
more certificates and converts them into a PKCS#7
degenerate "certificates only" structure.
COMMAND OPTIONS
-inform DER|PEM
This specifies the CRL input format. DER format is DER
encoded CRL structure.PEM (the default) is a base64
encoded version of the DER form with header and footer
lines.
-outform DER|PEM
This specifies the PKCS#7 structure output format. DER
format is DER encoded PKCS#7 structure.PEM (the
default) is a base64 encoded version of the DER form
with header and footer lines.
-in filename
This specifies the input filename to read a CRL from
or standard input if this option is not specified.
-out filename
specifies the output filename to write the PKCS#7
structure to or standard output by default.
-certfile filename
specifies a filename containing one or more
certificates in PEM format. All certificates in the
file will be added to the PKCS#7 structure. This
option can be used more than once to read certificates
form multiple files.
-nocrl
normally a CRL is included in the output file. With
this option no CRL is included in the output file and
a CRL is not read from the input file.
EXAMPLES
Create a PKCS#7 structure from a certificate and CRL:
openssl crl2pkcs7 -in crl.pem -certfile cert.pem -out p7.pem
Creates a PKCS#7 structure in DER format with no CRL from
several different certificates:
-certfile demoCA/cacert.pem -outform DER -out p7.der
NOTES
The output file is a PKCS#7 signed data structure
containing no signers and just certificates and an
optional CRL.
This utility can be used to send certificates and CAs to
Netscape as part of the certificate enrollment process.
This involves sending the DER encoded output as MIME type
application/x-x509-user-cert.
The PEM encoded form with the header and footer lines
removed can be used to install user certificates and CAs
in MSIE using the Xenroll control.
