-------------------------------------------------------------

is a dupe of CODEC-89 bug.
input is chunked also if input length is less than a chunk size.

using "Base64.encodeBase64(input)" work because by API is explicit "Encodes binary data using the base64 algorithm but does not chunk the output."

But "Base64.encodeBase64(input)" work correctly if the input never exceed 64 byte, for a long input should be add line separator as do "new Base64(64)"?

>          Issue Type: Bug
>    Affects Versions: 1.4

> Sometimes, a base64 encoded string ends inappropriately with \r\n characters.
> In the example below, i used value 64 as line lenght and the generated base64 string lenght was 44; nevertheless string ends with CRLF .
> (i think, this bug is not related to bug #CODEC-89)
> How to reproduce:
> {code:title=Test.java|borderStyle=solid}
> public class Test {
> 	public static void main(String args[]) throws Exception {
> 		byte[] input = new byte[] {
> 				25, 109, -39, -23, 82, -47, -88, 115, 
> 				-34, 126, -57, 16, -110, -110, 60, -7, 
> 				-123, -3, 60, 91, 112, -93, -67, -65, -71,
> 				-107, 123, -15, -106, 86, -80, 79
> 		};
> 		Base64 b64 = new Base64(64);
> 		String output = new String(b64.encode(input));
> 		System.out.println("*"+output+"*");
> 	}
> }
> {code}
> the output was: GW3Z6VLRqHPefscQkpI8+YX9PFtwo72/uZV78ZZWsE8=\r\n
