ECRECOVER function allows to infer from a hash and an associated ECDSA signature a list of public keys whose associated private keys may have generated the signature. From those candidate keys and some additional information, for example a bitcoin or Ethereum address, one can identify the correct public key whose companion private key signed the hash.
The function takes as input a parameter map with the following elements:
|The name of the ECC curve used by the key to recover.|
|Byte array of the hash which was signed.|
|Byte array of the signature, as generated by |
