pub fn sha256(&self, data: &[u8]) -> H256

Still pointing to the old implementation. Use the raw API if you need the new one. Will be changed after the new VM goes live. We also need to wait for the next minor release so we don’t break backwards compatibility.

pub fn ripemd160(&self, data: &[u8]) -> Box<[u8; 20]>

pub fn verify_bls(&self, key: &[u8], message: &[u8], signature: &[u8]) -> bool

pub fn verify_ed25519(
    &self,

) -> bool

pub fn verify_secp256k1(
    &self,
    key: &[u8],
    message: &[u8],
    signature: &[u8]
) -> bool

Note: the signature is minimum 2 bytes in length, the second byte encodes the length of the remaining signature bytes.
