@ -75,7 +75,7 @@ A new opcode `AUTH` shall be created at `0xf6`. It shall take four stack element
#### Behavior
The arguments (`yParity`, `r`, `s`) are interpreted as an ECDSA signature on the secp256k1 curve over the message `keccak256(MAGIC || paddedInvokerAddress || commit)`, where:
- `paddedInvokerAddress` is the address of the contract executing `AUTH`, left-padded with zeroes to a total of 32 bytes (ex. `0x000000000000000000000000AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA`).
- `paddedInvokerAddress` is the address of the contract executing `AUTH` (or the active state address in the context of `CALLCODE` or `DELEGATECALL`), left-padded with zeroes to a total of 32 bytes (ex. `0x000000000000000000000000AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA`).
- `commit`, one of the arguments passed into `AUTH`, is a 32-byte value that can be used to commit to specific additional validity conditions in the invoker's pre-processing logic (e.g. a nonce for replay protection).
Signature validity and signer recovery is handled analogous to transaction signatures, including the stricter `s` range for preventing ECDSA malleability. Note that `yParity` is expected to be `0` or `1`.
