openssl crl

CRL utility 

openssl command


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 

specifies the output format, the options have the same meaning and default 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 

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.

-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.

-hash_old 

outputs the "hash" of the CRL issuer name using the older algorithm as used by OpenSSL versions before 1.0.0.

-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 -inform DER -text -noout

BUGS

Ideally it should be possible to create a CRL using appropriate options and files too.
