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.
