Initially, the manual page entry for the 'openssl cmd' command used to be available at 'cmd(1)'. Later, the aliases 'openssl-cmd(1)' was introduced, which made it easier to group the openssl commands using the 'apropos(1)' command or the shell's tab completion. In order to reduce cluttering of the global manual page namespace, the manual page entries without the 'openssl-' prefix have been deprecated in OpenSSL 3.0 and will be removed in OpenSSL 4.0.

openssl-crl - CRL utility

|
[B<-help>]
|
|
[B<-inform PEM|DER>]
|
|

=head1 DESCRIPTION
|
|
|
|
The B<crl> command processes CRL files in DER or PEM format.
|
|
|
|
=head1 OPTIONS
|
|
|
|
=over 4
|
|
|
|
=item B<-help>
|
|
|
|
Print out a usage message.
|
|
|
|
=item B<-inform DER|PEM>
|
|
|
|
This specifies the input format. B<DER> format is DER encoded CRL
|
|
structure. B<PEM> (the default) is a base64 encoded version of
|
|
the DER form with header and footer lines.
|
|
|
|
=item B<-outform DER|PEM>
|
|
|
|
This specifies the output format, the options have the same meaning and default
|
|
as the B<-inform> option.
|
|
|
|
=item B<-in filename>
|
|
|
|
This specifies the input filename to read from or standard input if this
|
|
option is not specified.
|
|
|
|
=item B<-out filename>
|
|
|
|
Specifies the output filename to write to or standard output by
|
|
default.
|
|
|
|
=item B<-text>
|
|
|
|
Print out the CRL in text form.
|
|
|
|
=item B<-nameopt option>
|
|
|
|
Option which determines how the subject or issuer names are displayed. See
|
|
the description of B<-nameopt> in L<x509(1)>.
|
|
|
|
=item B<-noout>
|
|
|
|
Don't output the encoded version 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.
|
|
|
|
=item B<-CAfile file>
|
|
|
|
Verify the signature on a CRL by looking up the issuing certificate in
|
|
B<file>.
|
|
|
|
=item B<-CApath dir>
|
|
|
|
Verify the signature on a CRL by looking up the issuing certificate in
|
|
B<dir>. This directory must be a standard certificate directory: that
|
|
is a hash of each subject name (using B<x509 -hash>) should be linked
|
|
to each certificate.
|

|
=head1 NOTES
|
|
|
|
The PEM CRL format uses the header and footer lines:
|
|
|
|
-----BEGIN X509 CRL-----
|
|
-----END X509 CRL-----
|
|
|
|
=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 -inform DER -text -noout
|
|
|
|
=head1 BUGS
|
|
|
|
Ideally it should be possible to create a CRL using appropriate options
|
|
and files too.
