1krb5_c_prfplus - Generate pseudo-random bytes using RFC 6113 PRF+. 2==================================================================== 3 4.. 5 6.. c:function:: krb5_error_code krb5_c_prfplus(krb5_context context, const krb5_keyblock * k, const krb5_data * input, krb5_data * output) 7 8.. 9 10 11:param: 12 13 **[in]** **context** - Library context 14 15 **[in]** **k** - KDC contribution key 16 17 **[in]** **input** - Input data 18 19 **[out]** **output** - Pseudo-random output buffer 20 21 22.. 23 24 25 26:return: 27 - 0 on success, E2BIG if output->length is too large for PRF+ to generate, ENOMEM on allocation failure, or an error code from krb5_c_prf() 28 29.. 30 31 32 33 34 35 36 37This function fills *output* with PRF+(k, input) as defined in RFC 6113 section 5.1. The caller must preinitialize *output* and allocate the desired amount of space. The length of the pseudo-random output will match the length of *output* . 38 39 40 41 42 43 44 45 46 47 48.. 49 50 51 52 53 54 55.. note:: 56 57 RFC 4402 defines a different PRF+ operation. This function does not implement that operation. 58 59 60 61 62
