Bookmark or Share- The design of Chacha20Quick summary: Chacha20 is ARX-based hash function, keyed, running in counter mode. It embodies the idea that one can use a hash function to encrypt data. Stream ciphers. While Chacha20 is mainly used for encryption, its core is a pseudo-random number generator. The cipher text is obtained by XOR’ing the plain text with a pseudo-random stream:
- ChaCha20 | libsodiumChaCha20 is a stream cipher developed by Daniel J. Bernstein. Its original design expands a 256-bit key into 2^64 randomly accessible streams, each containing 2^64 randomly accessible 64-byte (512 bits) blocks. It is a variant of Salsa20 with better diffusion. ChaCha20 doesn’t require any lookup tables and avoids the possibility of timing ...
- Understanding ChaCha20 Encryption: A Secure and Fast Algorithm ... - MediumChaCha20 is a symmetric encryption algorithm that uses a 256-bit key for both encryption and decryption. It was developed by Daniel J. Bernstein, a renowned cryptographer, in 2008 as a stream...
- ChaCha20: The Dance of Cryptography - Network EncyclopediaWhat is ChaCha20? ChaCha20 is not a new dance move, though its name might suggest so. It’s a stream cipher—a means of encrypting data—that came into the limelight as a faster and, in many respects, more secure alternative to prevailing cryptographic standards.
- ChaCha20-Poly1305 - WikipediaChaCha20-Poly1305 is an authenticated encryption with additional data (AEAD) algorithm, that combines the ChaCha20 stream cipher with the Poly1305 message authentication code. Its usage in IETF protocols is standardized in RFC 8439.
