The crl command processes CRL files in DER or PEM format.
Print out a usage message.
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.
specifies the output format, the options have the same meaning and default as the
specifies the input file name to read from or standard input if this option is not specified.
specifies the output file name to write to or standard output by default.
print out the CRL in text form.
option which determines how the subject or issuer names are displayed. See the description of -nameopt in x509.
does not output the encoded version of the CRL.
outputs a hash of the issuer name. This can be use to lookup CRLs in a directory by issuer name.
outputs the "hash" of the CRL issuer name using the older algorithm as used by OpenSSL versions before 1.0.0.
outputs the issuer name.
outputs the lastUpdate field.
outputs the nextUpdate field.
verifies the signature on a CRL by looking up the issuing certificate in file.
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 -inform DER -text -noout
Ideally it should be possible to create a CRL using appropriate options and files too.
