I am note sure what is wrong with the below code. I am trying to encode an JPG file with base64 encoding. After encoding i am checking is it base64 encoded, it returns false. I am unable to find what is that I am missing.
public String encodeBinary64(String value){
String output = null;
System.out.println("encoding the binary length "+value.length());
byte[] byteArray = Base64.encodeBase64(value.getBytes());
output = Arrays.toString(byteArray);
System.out.println("output length encoding"+output.length());
Boolean base64Encoded = Base64.isBase64(output); -- returning FALSE
System.out.println("Base 64 Encoded "+ base64Encoded );
return output;
}
Update 2
The solution suggested below helped. However after decoding the base64 encoded image, when i try to open I am getting windows Photo Viewer Can't Open message. Below is the code.
public String decodeBinary64(String value){
String output = null;
System.out.println("Decoding the binary length "+value.length());
Boolean base64Encoded = Base64.isBase64(value);
System.out.println("base64Encoded "+base64Encoded);
if(base64Encoded){
byte[] byteArray = Base64.decodeBase64(value.getBytes());
try {
output = new String(byteArray, "UTF-8");
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println("output length "+output.length());
}
return output;
}
Note:
I have verified the length of the file before encoding and after decoding. The size remains the same. But the file is unable to open.
