crl2pkcs7(1ssl)crl2pkcs7(1ssl)NAMEcrl2pkcs7 - Creates a PKCS#7 structure from a CRL and certificates.
SYNOPSIS
openssl crl2pkcs7 [-inform PEM | DER] [-outform PEM | DER] [-in file‐
name] [-out filename] [-certfile filename] [-nocrl]
OPTIONS
Specifies the CRL input format. DER format is DER encoded CRL struc‐
ture.PEM (the default) is a base64 encoded version of the DER form with
header and footer lines. Specifies the PKCS#7 structure output format.
The DER format is DER encoded PKCS#7 structure. The PEM (the default)
is a base64 encoded version of the DER form with header and footer
lines. This specifies the input filename to read a CRL from or stan‐
dard input if this option is not specified. Specifies the output file‐
name to write the PKCS#7 structure to or standard output by default.
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 multi‐
ple files. 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.
DESCRIPTION
The crl2pkcs7 command takes an optional CRL and one or more certifi‐
cates and converts them into a PKCS#7 degenerate certificates only
structure.
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.
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 dif‐
ferent certificates:
openssl crl2pkcs7-nocrl-certfile newcert.pem -certfile
demoCA/cacert.pem -outform DER -out p7.der
