Hash functions

std::hash

sha2_256 and sha3_256 are available in std::hash.

module my_addrx::Hashing
{
    use std::hash;
    use std::bcs;
    use std::debug::print;
    
    fun hashing_in_move():vector<u8>
    {
        let x:vector<u8> = bcs::to_bytes<u64>(&10);
        let h = hash::sha2_256(x); 
        h 
    }

    #[test]
    fun testing()
    {
        let tmp=hashing_in_move();
        print(&tmp);
    }
}

std::aptos_hash

keccak256 ,sha2_512 ,sha3_512 ,ripemd160 are available in std::aptos_hash.

module std::Hashing
{
    use std::aptos_hash;
    use std::bcs;
    use std::debug::print;
    
    fun hashing_in_move():vector<u8>
    {
        let x:vector<u8> = bcs::to_bytes<u64>(&10);
        let h = aptos_hash::keccak256(x); 
        h 
    }

    #[test]
    fun testing()
    {
        let tmp=hashing_in_move();
        print(&tmp);
    }
}
