Base64 Encoding is different in Java and C# how to get same? [duplicate]

Question

in C#:

encryptionKey="Wb2bLNGXABcl4Lz........AxqA5Xhsoqi7w52RKA=";

var key = Convert.FromBase64String(encryptionKey);

key value={89,189,155,44,209,151,0,23,37,224,188,250,186,104,35,70,250,81,212,12,106,3,149,225,178,138,162,239,14,118,68,160}

in java:

byte[] key= Base64.decodeBase64(encryptionKey);

key={89,-67,-101,44,-47,-105,0,23,37,-32,-68,-6,-70,104,-21,70,-6,81,-44,12,106,3,-107,-31,-78,-118,-94,-17,14,118,68,-96};

key value is different in Java and C#. how to get same value in Java?

They are they same output. Java's displaying signed bytes, C# isn't. — awksp

It's the same. In the first case bytes are unsigned and Java bytes are signed. What we see in array is different interpretation of the same value, eg 189 and -67 = 0xBD

byte b = (byte) 189;

now b = -67
