Hi,

wolfSSL supports CRL verification, but as far as I know, it doesn't provide a command-line utility equivalent to OpenSSL's:

openssl crl -in crl.pem -text -noout

for displaying CRL contents in a human-readable format.

If your goal is to inspect a CRL, you can either:

Use OpenSSL's crl command to view the details, or
Write a small application using the wolfSSL API to parse and print the CRL information if you want to stay within the wolfSSL ecosystem.

If anyone knows of a built-in wolfSSL command that can print CRL information directly, I'd be interested to learn about it as well.
