openssl crl -- CRL utility

SYNOPSIS

openssl crl [-help] [-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.

Options

-help: Print out a usage message.
-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: specifies the output format, the options have the same meaning and default as the -inform option.
-in filename: specifies the input file name to read from or standard input if this option is not specified.
-out filename: specifies the output file name 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.
-noout: does not output the encoded version of the CRL.
-hash: outputs 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: outputs the issuer name.
-lastupdate: outputs the lastUpdate field.
-nextupdate: outputs the nextUpdate field.
-CAfile file: verifies 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 -inform DER -text -noout

BUGS

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