Julius Davies commented on CODEC-94:
------------------------------------
Just making sure this isn't a regression. Here's what I found:
- The only way to chunk the encoding in commons-codec-1.3 is via this static
method:
{code}
// 76 character chunking is hard-coded.
// 64 character chunking is not possible!
Base64.encodeBase64Chunked( byte[] data );
{code}
- commons-codec-1.3 appends a final CRLF no matter what when using "chunked"
mode:
[YWFhYWFhYWFhYWFhYWFhYWFhYWFhYWFhYWFhYWFhYWFhYWFhYWFhYWFhYWFhYWFhYWFhYWFhYWFh
YWFhYWFhYWFhYWFhYWFhYWFhYWFhYWFhYQ==
]
[YWFhYWFhYWFhYQ==
]
[YQ==
]
Question for Lorenzo: how would you feel about just calling new
String().trim() yourself?
A direct byte[] trim is also possible. Involves some System.arraycopy().
Maybe commons-codec could even offer up such a method ( bytesTrim() ).
> unexpected CRLF at end of base64 encoded string
> -----------------------------------------------
>
> Key: CODEC-94
> URL: https://issues.apache.org/jira/browse/CODEC-94
> Project: Commons Codec
> Issue Type: Bug
> Affects Versions: 1.4
> Environment: java 1.6u17
> ubuntu linux 9.10
> Reporter: Lorenzo Ingrillì
>
> 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
