The Advanced Encryption Standard (AES) is a symmetric-key encryption standard adopted by the U.S. government. The standard comprises three block ciphers, AES-128, AES-192 and AES-256, adopted from a larger collection originally published as Rijndael.

Is AES the recommended symmetric cipher for production level software?

I would love to support multiple algorithms like AES (GCM / CBC/ CTR) , XChaCha20-Poly1305 etc. … Also, AES GCM has a maximum size limit for messages ~ 64 GB, and I really wanted authentication with encryption! Should I stick with AES and its various modes (ex. …

Should I chunk or not for AES-GCM file encryption

AES GCM is a version of AES in counter mode, and a counter mode converts a block cipher into a stream cipher. The main advantage of a stream cipher is that we do not have to worry about padding. … We get 16 bytes of pseudo random key stream per invocation of the AES encryption function, which gets XOR ed with the plaintext to get the corresponding ciphertext. …
