krb5_k_prf - Generate enctype-specific pseudo-random bytes (operates on opaque key).

krb5_error_code krb5_k_prf(krb5_context context, krb5_key key, krb5_data * input, krb5_data * output)

param:

[in] context - Library context

[in] key - Key

[in] input - Input data

[out] output - Output data

retval:

• 0 Success; otherwise - Kerberos error codes

This function selects a pseudo-random function based on key and computes its value over input , placing the result into output . The caller must preinitialize output and allocate space for the result.

Note

This function is similar to krb5_c_prf(), but operates on opaque key .
