recoverNSignatures

Recover the signers of a message given the message and the signatures.

Usage

bytes32 dataHash = keccak256(abi.encodePacked("DATA TO SIGN"));
 
(uint8 v, bytes32 r, bytes32 s) = vm.sign(signerPk1, dataHash);
bytes memory signatures = abi.encodePacked(r, s, v);
(v, r, s) = vm.sign(signerPk2, dataHash);
signatures = abi.encodePacked(signatures, abi.encodePacked(r, s, v));
 
address[] memory recovered = CheckSignatures.recoverNSignatures(dataHash, signatures, 2);

Parameters

dataHash

• Type: bytes32

The hash of the data to sign.

signatures

• Type: bytes

The concatenated signatures. Note: the concatenation order is r, s, v and ther should not be any padding.

requiredSignatures

• Type: uint256

The number of signatures.

Returns

recoveredSigners

• Type: address[]

The array of addresses that signed the message.
