Values are: rfc_822 and iso_8601. 88Defaults to rfc_822. 89 90=item B<-text> 91 92Print out the CRL in text form. 93 94=item B<-verify> 95 96Verify the signature in the CRL. 97 98This option is implicitly enabled if any of B<-CApath>, B<-CAfile> 99or B<-CAstore> is specified. 100 101=item B<-noout> 102 103Don't output the encoded version of the CRL. 104 105=item B<-fingerprint> 106 107Output the fingerprint of the CRL. 108 109=item B<-crlnumber> 110 111Output the number of the CRL. 112 113=item B<-hash> 114 115Output a hash of the issuer name. This can be use to lookup CRLs in 116a directory by issuer name. 117 118=item B<-hash_old> 119 120Outputs the "hash" of the CRL issuer name using the older algorithm 121as used by OpenSSL before version 1.0.0. 122 123=item B<-issuer> 124 125Output the issuer name. 126 127=item B<-lastupdate> 128 129Output the lastUpdate field. 130 131=item B<-nextupdate> 132 133Output the nextUpdate field. 134 135{- $OpenSSL::safe::opt_name_item -} 136 137{- $OpenSSL::safe::opt_trust_item -} 138 139{- $OpenSSL::safe::opt_provider_item -} 140 141=back 142 143=head1 EXAMPLES 144 145Convert a CRL file from PEM to DER: 146 147 openssl crl -in crl.pem -outform DER -out crl.der 148 149Output the text form of a DER encoded certificate: 150 151 openssl crl -in crl.der -text -noout 152 153=head1 BUGS 154 155Ideally it should be possible to create a CRL using appropriate options 156and files too. 157 158=head1 SEE ALSO 159 160L<openssl(1)>, 161L<openssl-crl2pkcs7(1)>, 162L<openssl-ca(1)>, 163L<openssl-x509(1)>, 164L<ossl_store-file(7)> 165 166=head1 COPYRIGHT 167 168Copyright 2000-2024 The OpenSSL Project Authors.
