The Lightweight Encryption Algorithm (also known as LEA) is a 128-bit block cipher developed by South Korea in 2013 to provide confidentiality in high-speed environments such as big data and cloud computing, as well as lightweight environments such as IoT devices and mobile devices.

LEA is one of the cryptographic algorithms approved by the Korean Cryptographic Module Validation Program (KCMVP) and is the national standard of Republic of Korea (KS X 3246). LEA is included in the ISO/IEC 29192-2:2019 standard (Information security - Lightweight cryptography - Part 2: Block ciphers).

### Command-line Lightweight Encryption Algorithm Utility

Usage of leacrypt:

leacrypt [-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)

  -d    Decrypt instead 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.

  -s string

        Salt. (for PBKDF2)


### Example of encryption/decryption:

```sh

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

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

```
