### Grasshopper-MGM Encryption Tool

#### GOST R 34.12-2015 Kuznechik block cipher (RFC 7801) with Multilinear Galois Mode (MGM), June 2021 (RFC 9058).

Usage of gostcrypt:

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

  -a string

        Additional data.

  -d    Decrypt instead of Encrypt.

  -f string

        Target file.

  -i int

        Iterations. (for PBKDF2) (default 1024)

  -k string

        256-bit key to Encrypt/Decrypt.

  -p string

        PBKDF2.

  -r    Generate random 256-bit cryptographic key.

  -s string

        Salt. (for PBKDF2)

        

#### Example of encryption/decryption:

```sh

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

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

```
