OPENSSL-CRL(1ossl) OpenSSL OPENSSL-CRL(1ossl) 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] [-verify] [-noout] [-hash] [-hash_old] [-fingerprint] [-crlnumber] [-issuer] [-lastupdate] [-nextupdate] [-nameopt option] [-CAfile file] [-no-CAfile] [-CApath dir] [-no-CApath] [-CAstore uri] [-no-CAstore] [-provider name] [-provider-path path] [-provparam [name:]key=value] [-propquery propq] 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-op- tions(1) for details. -outform DER|PEM The CRL output format; the default is PEM. See openssl-format-op- tions(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 de- fault. -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 test- ing. -dateopt Specify the date output format. Values are: rfc_822 and iso_8601. De- faults to rfc_822. -text Print out the CRL in text form. -verify Verify the signature in the CRL. If the verification fails, the program will immediately exit, i.e. further option processing (e.g. -gendelta) is skipped. This option is implicitly enabled if any of -CApath, -CAfile or -CAs- tore is specified. -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-CAs- tore See "Trusted Certificate Options" in openssl-verification-options(1) for details. -provider name -provider-path path -provparam [name:]key=value -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.
