"@dev Returns the address that signed a hashed message (`hash`) with\n`signature`. This address can then be used for verification purposes.\n\t * The `ecrecover` EVM opcode allows for malleable (non-unique) signatures:\nthis function rejects them by requiring the `s` value to be in the lower\nhalf order, and the `v` value to be either 27 or 28.\n\t * NOTE: This call _does not revert_ if the signature is invalid, or\nif the signer is otherwise unable to be retrieved. In those scenarios,\nthe zero address is returned.\n\t * IMPORTANT: `hash` _must_ be the result of a hash operation for the\nverification to be secure: it is possible to craft signatures that\nrecover to arbitrary addresses for non-hashed data. A safe way to ensure\nthis is by receiving a hash of the original message (which may otherwise\nbe too long), and then calling {toEthSignedMessageHash} on it.", "id": 63, "implemented": true, "kind": "function", "modifiers": [], "name": "recover", "nodeType": "FunctionDefinition", "parameters": { "id": 6, "nodeType": "ParameterList", "parameters": [ { "constant": false, "id": 3, "name": "hash", "nodeType": "VariableDeclaration", "scope": 63, "src": "1194:12:0", "stateVariable": false, "storageLocation": "default", "typeDescriptions": { "typeIdentifier": "t_bytes32", "typeString": "bytes32" }, "typeName": { "id": 2, "name": "bytes32", "nodeType": "ElementaryTypeName", "src": "1194:7:0", "typeDescriptions": { "typeIdentifier": "t_bytes32", "typeString": "bytes32" } }, "value": null, "visibility": "internal" }, { "constant": false, "id": 5, "name": "signature", "nodeType": "VariableDeclaration", "scope": 63, "src": "1208:22:0", "stateVariable": false, "storageLocation": "memory", "typeDescriptions": { "typeIdentifier": "t_bytes_memory_ptr", "typeString": "bytes" }, "typeName": { "id": 4, "name": "bytes", "nodeType": "ElementaryTypeName", "src": "1208:5:0", "typeDescriptions": { "typeIdentifier": "t_bytes_storage_ptr", "typeString": "bytes" } }, "value": null, "visibility": "internal" } ], "src": "1193:38:0" }, "returnParameters": { "id": 9, "nodeType": "ParameterList", "parameters": [ { "constant": false, "id": 8, "name": "", "nodeType": "VariableDeclaration", "scope": 63, "src": "1255:7:0", "st
