You need to hash the signature scheme flag byte concatenated with the public key bytes using the BLAKE2b hashing function. The Sui address should be a 32-byte hash. The BLAKE2b hashing function is available in the [sui lib](https://github.com/MystenLabs/sui/blob/main/crates/sui-framework/packages/sui-framework/sources/crypto/hash.move). You can find a Rust example of this [here](https://docs.sui.io/guides/operator/exchange-integration#set-up-sui-addresses)
