CRL - File Format - Updating

Hey All,

 

 

We're looking to implement client certificate authentication and use a CRL.

 

 

1 - Updating the CRL file on a regular basis - best to do with a cron job?

 

 

2 - The CRL we are getting from the Cert Authority is in a .crl format. Since the LTM requires it to be a PEM formatted file, how would we go about doing that. All previous attempts to do so via Openssl have been unsuccessful.

 

 

Thanks in advance.

    Solved.

     

     

    .crl format is actually DER format. The openssl syntax that I had wasn't correct.

     

     

    bad syntax: openssl crl -in .crl -outform PEM -out .pem

     

    good syntax: openssl crl -inform der -in .crl -out .pem

     

     

    Still looking for suggestions as to if a cron job is the best / safest way to obtain the CRL.

     

     

    Thanks.
