# 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-options(1) for details.

-outform DER|PEM

  The CRL output format; the default is PEM. See openssl-format-options(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 default.

-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 testing.

-dateopt

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

  See openssl-verification-options(1)/Trusted Certificate Options for details.

-provider name
-provider-path path
-provparam [name:]key=value
-propquery propq

  See openssl(1)/Provider Options, 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.

# HISTORY

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