void coap_hash_impl | ( | const unsigned char * | s, |
size_t | len, | ||
coap_key_t | h | ||
) |
Calculates a fast hash over the given string s
of length len
and stores the result into h
.
Depending on the exact implementation, this function cannot be used as one-way function to check message integrity or simlar.
s | The string used for hash calculation. |
len | The length of s . |
h | The result buffer to store the calculated hash key. |
