Key: CAMEL-21505
URL: https://issues.apache.org/jira/browse/CAMEL-21505
Project: Camel
Issue Type: Bug
Components: camel-as2
Affects Versions: 4.8.1
Environment: Windows and Docker
Java 21 Temurin
Reporter: Meinolf S-D

Binary files get corrupt when using *base64* content transfer encoding due to
String assignment of the decoded byte[]
This can easily be tested sending a .zip file to Camel AS2 listener.
After some investigation the issue seems to be in the EntityUtil.decode method.
As shown in the screenshot the decoded (binary) byte[] is assigned to a new
String which result into corrupt date in case of binary content.

In addition there are new line characters in the encoded base64 encoded String
data object.
In case of using transfer encoding type *binary*
java.nio.charset.MalformedInputException: Input length = 1 it thrown which
might be OK.
