Answer

The answer is yes! you can use it with Firebase.

We have RNCryptor integrated into a project and are using it to encrypt and decrypt private data stored in Firebase.

Encrypt in ObjC

NSString *plainText = @"Hello!"
NSData *data = [plainText dataUsingEncoding:NSUTF8StringEncoding];
NSError *error;
NSData *encryptedData = [RNEncryptor encryptData:data
                                    withSettings:kRNCryptorAES256Settings
                                        password:aKey
                                           error:&error];

NSString *stringFromEncryptedData = [encryptedData 
         base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength];

Here's a decrypt pattern in ObjC

NSData *dataFromEncryptedString = [[NSData alloc] 
          initWithBase64EncodedString:encryptedString 
                              options:NSDataBase64DecodingIgnoreUnknownCharacters];
NSError *error;
NSData *decryptedData = [RNDecryptor decryptData:dataFromEncryptedString
                                    withPassword:aKey
                                           error:&error];

NSString *plainText = [[NSString alloc] initWithData:decryptedData
                                            encoding:NSUTF8StringEncoding];

Note that aKey is the secret string pattern you want to use to encrypt/decrypt your plain text string.
