ecdsa

ecdsa module for V language. Its a wrapper on top of openssl ecdsa functionality. Its currently (expanded) to support the following curves:

• NIST P-256 curve, commonly referred as prime256v1 or secp256r1
• NIST P-384 curve, commonly referred as secp384r1
• NIST P-521 curve, commonly referred as secp521r1
• A famous Bitcoin curve, commonly referred as secp256k1

Example

import crypto.ecdsa

fn main() {
    // create default NIST P-256 secp256r1 curve key pair. If you wish to generate another curve,
    // use: `pbkey, pvkey := ecdsa.generate_key(nid: .secp521r1)!` instead.
    pbkey, pvkey := ecdsa.generate_key()!

    message_tobe_signed := 'Hello ecdsa'.bytes()
    // create a signature with the recommended hash
    signature := pvkey.sign(message_tobe_signed)!

    // verify the message with the signature
    verified := pbkey.verify(message_tobe_signed, signature)!
    dump(verified) // should be true

    // free allocated keys when you have done with your work.
    pbkey.free()
    pvkey.free()
}
