crl − CRL utility
openssl crl [−inform PEM|DER] [−outform PEM|DER] [−text] [−in filename] [−out filename] [−noout] [−hash] [−issuer] [−lastupdate] [−nextupdate] [−CAfile file] [−CApath dir]
The crl command processes CRL files in DER or PEM format.
−inform DER|PEM
This specifies the 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.
−outform DER|PEM
This specifies the output format, the options have the same meaning as the −inform option.
−in filename
This specifies the input filename to read from or standard input if this option is not specified.
−out filename
specifies the output filename to write to or standard output by default.
−text
print out the CRL in text form.
−noout
don’t output the encoded version of the CRL .
−hash
output a hash of the issuer name. This can be use to lookup CRLs in a directory by issuer name.
−issuer
output the issuer name.
−lastupdate
output the lastUpdate field.
−nextupdate
output the nextUpdate field.
−CAfile file
verify the signature on a CRL by looking up the issuing certificate in file
−CApath dir
verify the signature on a CRL by looking up the issuing certificate in dir. This directory must be a standard certificate directory: that is a hash of each subject name (using x509 −hash) should be linked to each certificate.
The PEM CRL format uses the header and footer lines:
−−−−−BEGIN X509 CRL−−−−− −−−−−END X509 CRL−−−−−
Convert a CRL file from PEM to DER:
openssl crl −in crl.pem −outform DER −out crl.der
Output the text form of a DER encoded certificate:
openssl crl −in crl.der −text −noout
Ideally it should be possible to create a CRL using appropriate options and files too.
