Cryptography Builtins

Builtins.Sha256(data Bytes) -> (hash U256): The operator performs sha256 hashing on the bytes data passed and returns a 256-bit numeric hash

Builtins.Keccak(data Bytes) -> (hash U256):The operator performs keccak256 hashing on the bytes data passed and returns a 256-bit numeric hash

Builtins.Blake2b(data Bytes) -> (hash U256): The operator performs blake2b hashing on the bytes data passed and returns a 256-bit numeric hash

Builtins.Sigverify(data, signature Bytes) -> (ok Bool):It verifies the given data and signature are signed by the private key corresponding to the given public key and signature
