openssl-crl2pkcs7 - Create a PKCS#7 structure from a CRL and certificates
openssl crl2pkcs7 [-help] [-inform DER|PEM] [-outform DER|PEM] [-in filename] [-out filename] [-certfile filename] [-nocrl]
This command takes an optional CRL and one or more certificates and converts them into a PKCS#7 degenerate "certificates only" structure.
Print out a usage message.
- -inform DER|PEM
The input format of the CRL; the default is PEM. See "Format Options" in openssl(1) for details.
- -outform DER|PEM
The output format of the PKCS#7 object; the default is PEM. See "Format Options" in openssl(1) for details.
- -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.
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 command 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.
