# ECDSA Secp256r1

Minimalistic ECDSA/ECDH Tool written in Go 

### Usage:

 -derive

       Derive shared secret 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:

./ecdsa -keygen

#### Shared key negociation (ECDH):

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

#### Sign a file (ECDSA):

./ecdsa -sign -key $private < file.ext > sign.txt

sign=$(cat sign.txt)

./ecdsa -verify -key $public -signature $sign < file.ext
