## DESCRIPTION
       This command processes CRL files in DER or PEM format.

## OPTIONS
### -help
           Print out a usage message.

### -inform DER
           The CRL input format; unspecified by default.  See [**openssl-format-options**(1)](https://www.chedong.com/phpMan.php/man/openssl-format-options/1/markdown) for details.

### -outform DER
           The CRL output format; the default is **PEM**.  See [**openssl-format-options**(1)](https://www.chedong.com/phpMan.php/man/openssl-format-options/1/markdown) for details.

### -key _
           The private key to be used to sign the CRL.

### -keyform DER
           The    format    of    the    private    key   file;   unspecified   by   default.    See
           [**openssl-format-options**(1)](https://www.chedong.com/phpMan.php/man/openssl-format-options/1/markdown) for details.

### -in _
           This specifies the input filename to read from or standard input if this  option  is  not
           specified.

### -out _
           Specifies the output filename to write to or standard output by default.

### -gendelta _
           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.

### -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 _
           This   specifies   how   the   subject   or   issuer   names    are    displayed.     See
           [**openssl-namedisplay-options**(1)](https://www.chedong.com/phpMan.php/man/openssl-namedisplay-options/1/markdown) for details.

### -CAfile _ -no-CAfile -CApath _ -no-CApath -CAstore _ -no-CAstore
           See "Trusted Certificate Options" in [**openssl-verification-options**(1)](https://www.chedong.com/phpMan.php/man/openssl-verification-options/1/markdown) for details.

### -provider _
### -provider-path _
### -propquery _
           See "Provider Options" in [**openssl**(1)](https://www.chedong.com/phpMan.php/man/openssl/1/markdown), [**provider**(7)](https://www.chedong.com/phpMan.php/man/provider/7/markdown), and [**property**(7)](https://www.chedong.com/phpMan.php/man/property/7/markdown).

## 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.
