Returns a Result to let the caller choose an error handling strategy.

Additional Information

Follows the Secp256r1 elliptical curve.

Arguments

• signature: [B512] - The signature generated by signing a message hash.
• msg_hash: [b256] - The signed data.

Returns

• [Result<Address, EcRecoverError>] - The recovered Fuel address or an error.

Examples

use std::{ecr::ec_recover_address_r1, b512::B512};

fn foo() {
    let hi = 0xbd0c9b8792876713afa8bf3383eebf31c43437823ed761cc3600d0016de5110c;
    let lo = 0x44ac566bd156b4fc71a4a4cb2655d3dd360c695edb17dc3b64d611e122fea23d;
    let msg_hash = 0xee45573606c96c98ba970ff7cf9511f1b8b25e6bcd52ced30b89df1e4a9c4323;
    let address = Address::from(0xb4a5fabee8cc852084b71f17107e9c18d682033a58967027af0ab01edf2f9a6a);
    let signature: B512 = B512::from((hi, lo));
    // A recovered Fuel address.
    let result_address = ec_recover_address_r1(signature, msg_hash).unwrap();
    assert(result_address == address);
