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] [-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 "Trusted Certificate Options" in openssl-verification-options(1) for details.

-provider name
-provider-path path
-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.

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