NAME
       crl - CRL utility

SYNOPSIS
       openssl crl [-inform PEM|DER] [-outform PEM|DER] [-text] [-in filename] [-out filename]
       [-nameopt option] [-noout] [-hash] [-issuer] [-lastupdate] [-nextupdate] [-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 meaning 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.

       -nameopt option
	   option which determines how the subject or issuer names are displayed. See the
	   description of -nameopt in x509(1).

       -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.

       -hash_old
	   outputs the "hash" of the CRL issuer name using the older algorithm as used by OpenSSL
	   versions before 1.0.0.

       -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 certificate in file

       -CApath dir
	   verify the signature on a CRL by looking up the issuing certificate in dir. This
	   directory must be a standard certificate directory: 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.
