NAME
       openssl-crl - CRL command

SYNOPSIS
       openssl crl [-help] [-inform DER|PEM] [-outform DER|PEM] [-key filename] [-keyform
       DER|PEM|P12] [-dateopt] [-text] [-in filename] [-out filename] [-gendelta filename] [-badsig]

DESCRIPTION
       This command processes CRL files in DER or PEM format.

OPTIONS
       -help
           Print out a usage message.

       -inform DER|PEM
           The CRL input format; unspecified by default.  See openssl-format-options(1) for details.

       -outform DER|PEM
           The CRL output format; the default is PEM.  See openssl-format-options(1) for details.

       -key filename
           The private key to be used to sign the CRL.

       -keyform DER|PEM|P12
           The format of the private key file; unspecified by default.  See
           openssl-format-options(1) for details.

       -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.

       -gendelta filename
           Output a comparison of the main CRL and the one specified here.

       -badsig
           Corrupt the signature before writing it; this can be useful for testing.

       -dateopt
           Specify the date output format. Values are: rfc_822 and iso_8601.  Defaults to rfc_822.

       -text
           Print out the CRL in text form.

       -verify
           Verify the signature in the CRL.

       -noout
           Don't output the encoded version of the CRL.

       -fingerprint
           Output the fingerprint of the CRL.

       -crlnumber
           Output the number of the CRL.

       -hash
           Output a hash of the issuer name. This can be use to lookup CRLs in a directory by issuer
           name.

       -hash_old
           Outputs the "hash" of the CRL issuer name using the older algorithm as used by OpenSSL
           before version 1.0.0.

       -issuer
           Output the issuer name.

       -lastupdate
           Output the lastUpdate field.

       -nextupdate
           Output the nextUpdate field.

       -nameopt option
           This specifies how the subject or issuer names are displayed.  See
           openssl-namedisplay-options(1) for details.

       -CAfile file, -no-CAfile, -CApath dir, -no-CApath, -CAstore uri, -no-CAstore
           See "Trusted Certificate Options" in openssl-verification-options(1) for details.

       -provider name
       -provider-path path
       -propquery propq
           See "Provider Options" in openssl(1), provider(7), and property(7).

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.
