CRL2PKCS7(1) OpenSSL CRL2PKCS7(1)NAMEcrl2pkcs7 - Create a PKCS#7 structure from a CRL and certificates.
openssl crl2pkcs7 [-inform PEM⎪DER] [-outform PEM⎪DER] [-in filename]
[-out filename] [-certfile filename] [-nocrl]
The crl2pkcs7 command takes an optional CRL and one or more certifi‐
cates and converts them into a PKCS#7 degenerate "certificates only"
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.
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.
This specifies the input filename to read a CRL from or standard
input if this option is not specified.
specifies the output filename 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 certifi‐
cates form multiple files.

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‐
openssl crl2pkcs7-nocrl -certfile newcert.pem
-certfile demoCA/cacert.pem -outform DER -out p7.der
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
