### Command-line GM/T 0002-2012 SM4-GCM Encryption Tool

Usage of sm4crypt:

sm4crypt [-d] -p "pass" [-i N] [-s "salt"] -f <file.ext>

  -a string

        Additional Associated Data.

  -d    Decrypt instead of Encrypt.

  -f string

        Target file. ('-' for STDIN)

  -i int

  -k string

        128-bit key to Encrypt/Decrypt.

  -p string

        Password-based key derivation function2.

  -r    Generate random 128-bit cryptographic key.

  -s string

        Salt. (for PBKDF2)


### Example of encryption/decryption:

```sh

./sm4crypt -k $128bitkey -f plaintext.ext > ciphertext.ext

./sm4crypt -d -k $128bitkey -f ciphertext.ext > plaintext.ext

```
