NAME
crl - CRL utility
SYNOPSIS
openssl crl [-inform PEM|DER] [-outform PEM|DER] [-text]
[-in filename] [-out filename] [-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.
-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.
-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

CRL(1) 8/Feb/2000 (0.9.7e) CRL(1)-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.
