krb5_k_prf - Generate enctype-specific pseudo-random bytes (operates on opaque key).
======================================================================================
..
.. c:function:: 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 :c:func:`krb5_c_prf()` , but operates on opaque *key* .
