and use them like this



NSString *passphrase = @"1234567812345678";
NSStringEncoding myEncoding = NSASCIIStringEncoding;

NSString *alphaStringPlain = @"hello";

NSData *alphaDataPlain = [alphaStringPlain dataUsingEncoding:myEncoding];

NSData *alphaDataCypher = [alphaDataPlain AESEncryptWithPassphrase:passphrase];
NSString *alphaStringCypher = [[NSString alloc] initWithData:alphaDataCypher encoding:myEncoding];

NSLog(alphaStringCypher); // encode

///////
NSData *zCypher = [alphaDataCypher AESDecryptWithPassphrase:passphrase];
NSString *Cypher = [[NSString alloc] initWithData:zCypher encoding:myEncoding];


//NSData *zCypher = [alphaStringCypher AESDecryptWithPassphrase:passphrase];

NSLog(@" hua kya decode %@",[Cypher dataUsingEncoding:NSUTF8StringEncoding]);// decode
