random_seed(register_id: u64)

Returns random seed that can be used for pseudo-random number generation in deterministic way.

Panics​
  • If the size of the registers exceed the set limit MemoryAccessViolation;
sha256(value_len: u64, value_ptr: u64, register_id: u64)

Hashes the random sequence of bytes using sha256 and returns it into register_id.

Panics​
  • If value_len + value_ptr points outside the memory or the registers use more memory than the limit with MemoryAccessViolation.
keccak256(value_len: u64, value_ptr: u64, register_id: u64)

Hashes the random sequence of bytes using keccak256 and returns it into register_id.

Panics​
  • If value_len + value_ptr points outside the memory or the registers use more memory than the limit with MemoryAccessViolation.
keccak512(value_len: u64, value_ptr: u64, register_id: u64)

Hashes the random sequence of bytes using keccak512 and returns it into register_id.

Panics​
  • If value_len + value_ptr points outside the memory or the registers use more memory than the limit with MemoryAccessViolation.
