crl2pkcs7 — 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
certificates and converts them into a PKCS#7 degenerate "certificates
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 certificates
form multiple 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.
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:
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
