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]


This command processes CRL files in DER or PEM format.



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.


Corrupt the signature before writing it; this can be useful for testing.


Specify the date output format. Values are: rfc_822 and iso_8601. Defaults to rfc_822.


Print out the CRL in text form.


Verify the signature in the CRL.

This option is implicitly enabled if any of -CApath, -CAfile or -CAstore is specified.


Don’t output the encoded version of the CRL.


Output the fingerprint of the CRL.


Output the number of the CRL.


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


Outputs the "hash" of the CRL issuer name using the older algorithm as used by OpenSSL before version 1.0.0.


Output the issuer name.


Output the lastUpdate field.


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,

See "Trusted Certificate Options" in openssl-verification-options(1) for details.

-provider name

See "Provider Options" in openssl(1), provider(7), and property(7).


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


Ideally it should be possible to create a CRL using appropriate options and files too.
