 ## Why not using authenticated encryption such as AES-GCM instead of AES-CTR + HMAC ?
 
-In order to encrypt data larger than memory, we need to split the plaintext into severavl smaller chunks and encrypt each of these chunks one by one. With authenticated encryption such as AES-GCM, this involves adding an authentication tag to each chunk. As a result, the final ciphertext size would be:

+doby aims to be a small, fast and user-friendly command line tool for symmetric encryption of single files. It uses modern cryptography and (obviously) it's built in rust.
 
 doby can operate with files larger than memory but also from stdout/stdin. In addition to encrypt files, doby also use HMAC cryptography to authenticate the data. This means that encrypted files can't be tampered. Encryptions keys are derived from the user password using Argon2, an expensive KDF function that slows down a lot brute force attacks. You can find more details about cryptography on the doby's repository: https://forge.chapril.org/hardcoresushi/doby#cryptographic-details
