krb5_error_code krb5_c_verify_checksum (
        krb5_context            context,
        const krb5_keyblock     *key,
        krb5_keyusage           usage,

Arguments

context (input/output) 

The context structure.

key (input)  

The key used to create the data in cksum.

usage (input)

data (input) 

Data.

cksum (input)  

The checksum to verify.

valid (output)
