WebMar 20, 2024 · One of the earliest encoding schemes, called ASCII (American Standard Code for Information Exchange) uses a single-byte encoding scheme. This essentially means that each character in ASCII is represented with seven-bit binary numbers. This still leaves one bit free in every byte! ASCII's 128-character set covers English alphabets in … In practice, ChaCha is mostly used as the ChaCha20-Poly1305 variant, which is also recommended. The Private Keyis always 256 Bits (32 Bytes).
