Detailed Description

BLAKE2b hash algorithm.

BLAKE2b is a variation on the ChaCha stream cipher, designed for hashing, with a 512-bit hash output. It is intended as a high performance replacement for SHA512 for when speed is critical but exact SHA512 compatibility is not.

-

Reference: https://blake2.net/

+

This class supports two types of keyed hash. The BLAKE2 keyed hash and traditional HMAC. The BLAKE2 keyed hash is recommended unless there is some higher-level application need to be compatible with the HMAC construction. The keyed hash is computed as follows:

+
BLAKE2b blake;
+
blake.reset(key, sizeof(key), outputLength);
+
blake.update(data1, sizeof(data1));
+
blake.update(data2, sizeof(data2));
+
...
+
blake.update(dataN, sizeof(dataN));
+
blake.finalize(hash, outputLength);
+

The HMAC is computed as follows (the output length is always 64):

+
BLAKE2b blake;
+
blake.resetHMAC(key, sizeof(key));
+
blake.update(data1, sizeof(data1));
+
blake.update(data2, sizeof(data2));
+
...
+
blake.update(dataN, sizeof(dataN));
+
blake.finalizeHMAC(key, sizeof(key), hash, 32);
+

All cryptographic algorithms have been optimized for 8-bit Arduino platforms like the Uno. Memory usage is also reduced, particularly for SHA256 and SHA512 which save 192 and 512 bytes respectively over traditional implementations. For all algorithms, static sbox tables and the like are placed into program memory to further reduce data memory usage.

ChaCha with 20 rounds and 256-bit keys is the recommended symmetric encryption algorithm because it is twice as fast as AES128, constant-time, and much more secure. AES128, AES192, and AES256 are provided for use in applications where compatibility with other systems is desirable.

If code size is an issue for your application (for example on very low end Arduino variants), then Speck on AVR is less than half the code size of ChaCha, at the cost of more data memory for the state and longer key setup times. The SpeckTiny and SpeckSmall classes are even smaller at the cost of some performance when encrypting.

BLAKE2s and BLAKE2b are variations on the ChaCha stream cipher, designed for hashing, with 256-bit and 512-bit hash outputs respectively. They are intended as high performance replacements for SHA256 and SHA512 for when speed is critical but exact bit-compatibility of hash values is not.

They are intended as high performance replacements for SHA256 and SHA512 for when speed is critical but exact bit-compatibility of hash values is not. BLAKE2s and BLAKE2b support regular hashing, BLAKE2 keyed hashing, and HMAC modes.
