Which symmetric encryption to use. How to encrypt texts with SHA-256.

When it comes to symmetric encryption, you only have three good choices today: ChaCha20 or any of its derivatives, AES-256 or SHA-256.

AES-256 has special acceleration hardware dedicated to it.
ChaCha20 is faster out of the box, if there is no dedicated AES hardware. ChaCha20 works by taking in a nonce, a pseudorandom 96-bit-input, deriving a unique key from your nonce and password and then generating a stream of high-entropy pseudorandom bits that can be XORed with the plaintext. There …
