random_seed

#![allow(unused)] fn main() { 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

#![allow(unused)] fn main() { 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

#![allow(unused)] fn main() { 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

#![allow(unused)] fn main() { 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.
