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:

EXAMPLES

Convert a CRL file from PEM to DER:

Output the text form of a DER encoded certificate:

BUGS

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