CRL(1SSL) OpenSSL CRL(1SSL)
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.
