It can also transform into the EVM address: 0xf3b4e49Fd77A959B704f6a045eeA92bd55b3b571

The Signature Calculation

The signature string is: [account_and_auth_type_hash]:[request_id]

The signature algorithm is ETH compatible, same as this: ethers.utils.keccak256(ethers.utils.toUtf8Bytes(value))

Following are the sample code of signature process.
