Keystore Encryption Algorithm

Account Address Encryption Algorithm

T0 Address

1. get public_key: secp256k1 private_key(256bit) -> public_key(512bit)
2. get hash: sha2_256 then rip160 public_key(512bit) -> rip160(sha2_256(public_key)) = hash
3. add version: char '0' or hex '0x30' ['0',hash] -> version-hash
4. calc checksum: sha2_256 twice version-hash -> sha2_256(sha2_256(version-hash)) = checksum
5. get address bytes: [hash, checksum_hash[0..4]] -> address_bytes
6. get T0 address: base58::encode T0_address = "T00000" + address_bytes.to_base58()

T8 Address

1. get public_key: secp256k1 private_key(256bit) -> public_key(512bit)
2. get hash: keccak256 public_key[1..] -> keccak256(public_key[1..]) = hash
3. get eth address: eth_address = hex::encode(hash[12..])
4. get T8 address: T8_address = "T80000" + eth_address
