Implementations

impl GoogleCloudKmsService

pub fn new(config: &GoogleCloudKmsSignerConfig) -> GoogleCloudKmsResult<Self>

pub async fn sign_payload_evm( &self, bytes: &[u8], ) -> GoogleCloudKmsResult<Vec<u8>>

Signs a payload using the EVM signing scheme (hashes before signing).

This method applies keccak256 hashing before signing.

Use for:

• Raw transaction data (TxLegacy, TxEip1559)
• EIP-191 personal messages

Note: For EIP-712 typed data, use sign_hash_evm() to avoid double-hashing.

pub async fn sign_hash_evm( &self, hash: &[u8; 32], ) -> GoogleCloudKmsResult<Vec<u8>>

Signs a pre-computed hash using the EVM signing scheme (no hashing).

This method signs the hash directly without applying keccak256.

Use for:

• EIP-712 typed data (already hashed)
• Pre-computed message digests

Note: For raw data, use sign_payload_evm() instead.
