+ [−]
+
+ [src]
+pub struct HMAC {
+ // some fields omitted
+}Provides HMAC computation.
+ +Examples
+Calculate a HMAC in one go.
++use openssl::crypto::hash::Type; +use openssl::crypto::hmac::hmac; +let key = b"Jefe"; +let data = b"what do ya want for nothing?"; +let spec = b"\x75\x0c\x78\x3e\x6a\xb0\xb5\x03\xea\xa8\x6e\x31\x0a\x5d\xb7\x38"; +let res = hmac(Type::MD5, key, data); +assert_eq!(res, spec); ++ +
Use the Write trait to supply the input in chunks.

Methods
impl HMAC
fn new(ty: Type, key: &[u8]) -> HMAC
+Creates a new HMAC with the specified hash type using the key.
fn finish(&mut self) -> Vec<u8>
+Returns the hash of the data written since creation or
+the last finish and resets the hasher.
