pub fn calculate_signature(
    ctx: &Context,
    private: &PrivateKey,
    message: &[u8],
) -> Result<Buffer, Error>

Calculate the signature for a message.

Examples

This is the counterpart to PublicKey::verify_signature.

// the `Crypto` here is a type alias to one of `OpenSSLCrypto` or `DefaultCrypto`.
let ctx = Context::new(Crypto::default()).unwrap();
let key_pair = libsignal_protocol::generate_key_pair(&ctx)?;

let msg = "Hello, World!";
let private_key = key_pair.private();
let signature = libsignal_protocol::calculate_signature(
    &ctx,
    &private_key,
    msg.as_bytes(),
)?;

let public = key_pair.public();
let got = public.verify_signature(msg.as_bytes(), signature.as_slice());
assert!(got.is_ok());
