Function ink_env::sr25519_verify

pub fn sr25519_verify(
    signature: &[u8; 64],
    message: &[u8],
    pub_key: &[u8; 32]
) -> Result<()>

Verifies a sr25519 signature.

Example

let signature: [u8; 64] = [
    184, 49, 74, 238, 78, 165, 102, 252, 22, 92, 156, 176, 124, 118, 168, 116, 247,
    99, 0, 94, 2, 45, 9, 170, 73, 222, 182, 74, 60, 32, 75, 64, 98, 174, 69, 55, 83,
    85, 180, 98, 208, 75, 231, 57, 205, 62, 4, 105, 26, 136, 172, 17, 123, 99, 90,
    255, 228, 54, 115, 63, 30, 207, 205, 131,
];
let message: &[u8; 11] = b"hello world";
let pub_key: [u8; 32] = [
    212, 53, 147, 199, 21, 253, 211, 28, 97, 20, 26, 189, 4, 169, 159, 214, 130, 44,

];

let result = ink::env::sr25519_verify(&signature, message.as_slice(), &pub_key);
assert!(result.is_ok())

Errors
