Authenticated Encryption (AE) is an encryption scheme which simultaneously assures the data confidentiality (also known as privacy: the encrypted message is impossible to understand without the knowledge of a secret key [1]) and authenticity (in other words, it is unforgeable: [2] the encrypted message includes an authentication tag that the sender can calculate only while possessing the ...
ChaCha20-Poly1305 is an authenticated encryption with associated data (AEAD) algorithm, that combines the ChaCha20 stream cipher with the Poly1305 message authentication code. [1] It has fast software performance, and without hardware acceleration, is usually faster than AES-GCM. [1]: §B
GCM was designed by John Viega and David A. McGrew to be an improvement to Carter–Wegman counter mode (CWC mode). [4] In November 2007, NIST announced the release of NIST Special Publication 800-38D Recommendation for Block Cipher Modes of Operation: Galois/Counter Mode (GCM) and GMAC making GCM and GMAC official standards.

EAX mode (encrypt-then-authenticate-then-translate [1]) is a mode of operation for cryptographic block ciphers. It is an Authenticated Encryption with Associated Data algorithm designed to simultaneously provide both authentication and privacy of the message (authenticated encryption) with a two-pass scheme, one pass for achieving privacy and one for authenticity for each block.
AES speed at 128, 192 and 256-bit key sizes. [clarification needed] [citation needed] Rijndael is free for any use public or private, commercial or non-commercial. [1] The authors of Rijndael used to provide a homepage [2] for the algorithm. Care should be taken when implementing AES in software, in particular around side-channel attacks.
Earlier this week, a cat named Rosie, who could have been the world’s oldest feline, passed away at the age of 33. The feline was a beautiful tortoiseshell cat and reached 152 human years ...
