=head1 DESCRIPTION |
|
|
|
The B<crl> command processes CRL files in DER or PEM format. |
|
|
|
=head1 COMMAND OPTIONS |
|
|
|
=over 4 |
|
|
|
=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 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)|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 versions before 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 -text -noout |
|
|
|
=head1 BUGS |
|
|
|
Ideally it should be possible to create a CRL using appropriate options |
|
and files too. |
