NAME

openssl-crl, 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 This specifies the output format, the options have the same meaning and default 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 before version 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 -inform DER -text -noout

BUGS

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