crl - CRL utility


SYNOPSIS

       openssl crl [-inform PEM|DER] [-outform PEM|DER] [-text]
       [-in filename] [-out filename] [-noout] [-hash] [-issuer]
       [-lastupdate] [-nextupdate] [-CAfile file] [-CApath dir]


DESCRIPTION

       The crl command processes CRL files in DER or PEM format.


COMMAND OPTIONS

       -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

           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.


NOTES

       The PEM CRL format uses the header and footer lines:

        -----BEGIN X509 CRL-----
        -----END X509 CRL-----


EXAMPLES

       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


BUGS

       Ideally it should be possible to create a CRL using
       appropriate options and files too.
