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

[in] context - Library context

[in] keyblock - Key

[in] input - Input data

[out] output - Output data

  • 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.
