Webb1 apr. 2024 · 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.
