NAME
       crl - CRL utility

SYNOPSIS
       openssl crl [-inform PEM│DER] [-outform PEM│DER] [-text] [-in file-
       name] [-out filename] [-noout] [-hash] [-issuer] [-lastupdate] [-nex-
       tupdate] [-CAfile file] [-CApath dir]

DESCRIPTION
       The crl command processes CRL files in DER or PEM format.

COMMAND OPTIONS
       -inform DER│PEM
	   This specifies the input format. DER format is DER encoded CRL
	   structure. PEM (the default) is a base64 encoded version of the
	   DER form with header and footer lines.

       -outform DER│PEM
	   This specifies the output format, the options have the same mean-
	   ing as the -inform option.

       -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.

       -text
	   print out the CRL in text form.

       -noout
	   don’t output the encoded version of the CRL.

       -hash
	   output a hash of the issuer name. This can be use to lookup CRLs
	   in a directory by issuer name.

       -issuer
	   output the issuer name.

       -lastupdate
	   output the lastUpdate field.

       -nextupdate
	   output the nextUpdate field.

       -CAfile file
	   verify the signature on a CRL by looking up the issuing certifi-
	   cate in file

       -CApath dir
	   verify the signature on a CRL by looking up the issuing certifi-
	   cate in dir. This directory must be a standard certificate direc-
	   tory: that is a hash of each subject name (using x509 -hash)
	   should be linked to each certificate.

NOTES
       The PEM CRL format uses the header and footer lines:

	-----BEGIN X509 CRL-----
	-----END X509 CRL-----

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.
