Rijndael, Serpent, RC6 and Twofish with Galois/Counter Mode (AES-GCM) provides both authenticated encryption (confidentiality and authentication) and the ability to check the integrity and authentication of additional authenticated data (AAD) that is sent in the clear. AES-GCM is specified in NIST Special Publication 800-38D ([SP800-38D](https://csrc.nist.gov/publications/detail/sp/800-38d/final)).

### Command-line AES-GCM Encryption Tool

Usage of aescrypt:

aescrypt [-d] [-b N] -p "pass" [-i N] [-s "salt"] -f <file.ext>

 -a string

       Additional authenticated data.

 -b int

       Key length: 128, 192 or 256. (default 256)

 -c string

       Cipher: AES, RC6, Twofish or Serpent. (default "aes")

 -d    Decrypt instead of Encrypt.

 -f string

       Target file. ('-' for STDIN)

 -i int

       Iterations. (for PBKDF2) (default 1024)

 -k string

       Symmetric key to Encrypt/Decrypt.

 -m    Cipher-based message authentication code.

 -p string

       Password-based key derivation function 2.

 -r    Generate random cryptographic key with given bit-length.

 -s string

       Salt. (for PBKDF2)


### Example of encryption/decryption:

```sh

./aescrypt -k "" -f plaintext.ext > ciphertext.ext

./aescrypt -d -k $256bitkey -f ciphertext.ext > plaintext.ext

```
