Poly1305-AES is a state-of-the-art message-authentication code suitable for a wide variety of applications. Poly1305-AES computes a 16-byte authenticator of a variable-length message, …

Poly1305 stands out among modern cryptographic algorithms for its unique mathematical foundation and exceptional performance. Developed by Daniel J. Bernstein in 2005, Poly1305 …

Poly1305 is an authenticator that takes a 32-byte key and a message and produces a 16-byte tag. This tag is used to authenticate the message. Each key must only be used once. Using the …

Poly1305 is a universal hash function suitable for use as a one-time authenticator and, when combined with a cipher, a message authentication code (MAC). It takes a 32-byte one-time …

Mar 17, 2025 · Poly1305 [Poly1305], also by Daniel Bernstein, is a one-time Carter-Wegman MAC that computes a 128 bit integrity tag given a message and a single-use 256 bit secret …

Poly1305 is a one-time message authentication code. “One-time” means the authentication key can be used only once. This makes Poly1305 easy to misuse. On the other hand, Poly1305 is …

Jun 11, 2025 · Poly1305 is a message authentication code that generates a tag based on the ciphertext and a secret key. The tag is used to verify the authenticity of the ciphertext.

The XChaCha20-Poly1305 construction is an extended 192-bit nonce variant of the ChaCha20-Poly1305 construction, using XChaCha20 instead of ChaCha20. When choosing nonces at …

Poly1305 [POLY1305] is a Wegman-Carter, one-time authenticator designed by D. J. Bernstein. Poly1305 takes a 256-bit, one-time key and a message, and it produces a 16-byte tag that …
