byte[] format

I have the code :

byte[] messageCrypte = encryptCipher.doFinal(messageACrypter);
String ms = new String(messageCrypte);
byte[] bt = ms.getBytes();

bt has not the same format as messageCrypted.

Why?

What do you mean by 'format'?

If the default character encoding is lossy, then characters could be lost in
the byte-char-byte conversion.

Because you applied character set translations. Look at the source
code. There are deprecated String methods that operate on raw bytes
without translation. Better yet, don't use String for byte array
storage.
