# Configuring a Sample CRL

In the following example, a CRL list with certificate authorities is located in a directory with a hashed file name.

## Prerequisites

Ensure that you already have a CRL list configured with the file name.

## Procedure

1. On the command line, navigate to the $CFROOT/config directory.
2. Type the following command to replace the my.crl file with the absolute file path.
   `./openssl crl -hash -noout -in my.crl`
   The output screen is expected to be:

       > ./openssl crl –hash –noout –in my.crl
       592b5bc9

   In this case, the hashed value is generated as 592b5bc9.
3. Type the following commands with the generated hash value in Step 2.

   `cp <your certificate authority file> /usr/CAfiles/592b5bc9.0`

   `cp my.crl /usr/CAfiles/592b5bc9.r0`

4. Open the $CFROOT/config/config.txt file, modify the CAPath parameter to the directory where you have placed the hashed files in Step 3.
   For this example, the CAPath parameter is set to `/usr/CAfiles`.
