=head1 DESCRIPTION

This command processes CRL files in DER or PEM format.

=head1 OPTIONS

=over 4

=item B<-help>

Print out a usage message.

=item B<-inform> B<DER>|B<PEM>

The CRL input format; unspecified by default.
See L<openssl-format-options(1)> for details.

=item B<-outform> B<DER>|B<PEM>

The CRL output format; the default is B<PEM>.
See L<openssl-format-options(1)> for details.

=item B<-key> I<filename>

The private key to be used to sign the CRL.

=item B<-keyform> B<DER>|B<PEM>|B<P12>

The format of the private key file; unspecified by default.
See L<openssl-format-options(1)> for details.

=item B<-in> I<filename>

This specifies the input filename to read from or standard input if this
option is not specified.

=item B<-out> I<filename>

Specifies the output filename to write to or standard output by
default.

=item B<-gendelta> I<filename>

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

=item B<-badsig>

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

=item B<-dateopt>

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

=item B<-text>

Print out the CRL in text form.

=item B<-verify>

Verify the signature in the CRL. If the verification fails,
the program will immediately exit, i.e. further option processing
(e.g. B<-gendelta>) is skipped.

This option is implicitly enabled if any of B<-CApath>, B<-CAfile>
or B<-CAstore> is specified.

=item B<-noout>

Don't output the encoded version of the CRL.

=item B<-fingerprint>

Output the fingerprint of the CRL.

=item B<-crlnumber>

Output the number of the CRL.

=item B<-hash>

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

=item B<-hash_old>

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

=item B<-issuer>

Output the issuer name.

=item B<-lastupdate>

Output the lastUpdate field.

=item B<-nextupdate>

Output the nextUpdate field.

=back

=head1 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

=head1 BUGS

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

=head1 HISTORY

Since OpenSSL 3.3, the B<-verify> option will exit with 1 on failure.
