### GOST R 34.10-2012 512-bit curve ParamSet A and B

Package implements the elliptic curves originally described in RFC 7836

## Usage

```

Usage of gost2012:

  -dec

        Decrypt with Private key

  -derive

        Derive shared secret key

  -enc

        Encrypt with Public key

  -key string

        Private/Public key

  -keygen

        Generate keypair

  -pub string

        Remote's side Public key

  -sign

        Sign with Private key

  -signature string

        Signature

  -verify

        Verify with Public key

```

## Examples

#### Asymmetric keypair generation:

```sh

./gost2012 -keygen 

```

#### Digital signature (ECDSA):

```sh

./gost2012 -sign -key $prvkey < file.ext > sign.txt

sign=$(cat sign.txt)

./gost2012 -verify -key $pubkey -signature $sign < file.ext

```

#### Asymmetric Encryption:

```sh

./gost2012 -enc -key $pubkey < file.ext > file.enc

./gost2012 -dec -key $prvkey < file.enc

```

#### Shared key agreement (ECDH a.k.a. VKO):

```sh

./gost2012 -derive -key $prvkey -pub $pubkey

```
