# 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 .
