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:
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.
