Converting base64 encoded bytes to string different in Java and C#

Question

I have some code to login to a 3rd party solution, that requires me to encode a password. They have provided me with a sample in Java, but I also need to develop it in C# (and PHP, later). I have the code in a C# Windows app, and a Java Android app, and with the same output, they seem to work well up until the point where I try and convert the cypher bytes to a base 64 encoded string. Here is the Java code: ``` enc = Base64.encodeBase64(ciphertext); return enc.toString(); ``` And here is the C# code: ``` return System.Convert.ToBase64String(cipherBytes); ``` I can see that the ciphertext bytes in the Java app are the same as in the C# app, except that they are signed, and that the base64 encoded bytes in Java, if converted to ASCII values, would give the string that I am seeing in the C# app, but the enc.ToString() in Java is not returning that same string. More info Java ``` ciphertext = 66, 67, -69, 24, -48, -23, 84, -5 encodeded64 = 81, 107, 79, 55, 71, 78, 68, 112, 86, 80, 115, 61…

Accepted Answer

The Java code you're using is calling `toString()` on a byte array, which will always give you a string of the form `[B@....`

You could use:

```
return new String(enc, "ASCII");
```

... but I would suggest changing to use an API where encoding a byte array gives you back a string to start with. I like this public domain implementation.

```
return Base64.encodeBytes(cipherText);
```
