AESCrypt

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).

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:

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