openssl-crl2pkcs7, crl2pkcs7 - Create a PKCS#7 structure from a CRL and
openssl crl2pkcs7 [-help] [-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 only"
Create a PKCS#7 structure from a certificate and CRL:
- Print out a usage message.
- -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. The default format is PEM.
- -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. The default format
- -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
from 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
openssl crl2pkcs7 -in crl.pem -certfile cert.pem -out p7.pem
Creates a PKCS#7 structure in DER format with no CRL from several
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
