Module hash 

Poseidon2 hash functions for the Aztec protocol.

Provides poseidon2_hash_with_separator and derived functions that mirror the TypeScript SDK’s hashing utilities.

Structs

ChainInfo

Chain identification information.

Enums

MessageHashOrIntent

Either a raw message hash, a structured call intent, or a pre-computed inner hash with its consumer address.

Functions

abi_values_to_fields

Flatten ABI values into their field element representation.

buffer_as_fields

Encode a byte buffer as field elements (31 bytes per field).

compute_artifact_hash

Compute the artifact hash for a contract.

compute_auth_wit_message_hash

Compute the full authwit message hash from an intent and chain info.

compute_contract_address_from_instance

Compute the contract address from a ContractInstance.

compute_contract_class_id

Compute the contract class ID from its components.

compute_contract_class_id_from_artifact

Compute contract class ID directly from a ContractArtifact.

compute_initialization_hash

Compute the initialization hash for a contract deployment.

compute_initialization_hash_from_encoded

Compute initialization hash from pre-encoded selector and args.

compute_inner_auth_wit_hash

Compute the inner authwit hash — the “intent” before siloing with consumer.

compute_inner_auth_wit_hash_from_action

Compute the inner authwit hash from a caller address and a function call.

compute_outer_auth_wit_hash

Compute the outer authwit hash — the value the approver signs.

compute_partial_address

Compute the partial address from class ID and salted init hash.

compute_private_functions_root

Compute the root of the private functions Merkle tree.

compute_private_functions_root_from_artifact

Extract private functions from an artifact and compute the root.

compute_public_bytecode_commitment

Compute the commitment to packed public bytecode.

compute_salted_initialization_hash

Compute the salted initialization hash.

compute_var_args_hash

Hash function arguments using Poseidon2 with the FUNCTION_ARGS separator.

poseidon2_hash_with_separator

Compute a Poseidon2 hash of inputs with a domain separator prepended.

poseidon2_hash_with_separator_field

Compute a Poseidon2 hash of inputs with a full field-element domain separator prepended.
