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.
