SYNOPSIS
openssl crl
[
DESCRIPTION
The crl command processes CRL files in DER or PEM format.
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-
specifies the output format, the options have the same meaning 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 -
prints out the CRL in text form.
-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.
-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 -text -noout
BUGS
Ideally it should be possible to create a CRL using appropriate options and files too.
