NAME
crl - CRL utilitySYNOPSIS
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
- -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.SEE ALSO
