# krb5_c_prf - Generate enctype-specific pseudo-random bytes.

krb5_error_code `krb5_c_prf`(krb5_context context, const krb5_keyblock * keyblock, krb5_data * input, krb5_data * output)

param: | [in] context - Library context [in] keyblock - 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 keyblock and computes its value over input , placing the result into output . The caller must preinitialize output and allocate space for the result, using `krb5_c_prf_length()` to determine the required length.
