       [-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
       -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.

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