Gary Gregory commented on CODEC-99:
-----------------------------------

IMO, the issue is not chunk vs. not chunk but that the output should never 
encode and end in a CR LR, especially when there is no = at the end of the 
output

> Base64.encodeBase64String() shouldn't chunk

> Base64.encodeBase64String() shouldn't chunk.
> Change this:
> {code}
> public static String encodeBase64String(byte[] binaryData) {
>     return StringUtils.newStringUtf8(encodeBase64(binaryData, true));
> }
> {code}
> To this:
> {code}
> public static String encodeBase64String(byte[] binaryData) {
>     return StringUtils.newStringUtf8(encodeBase64(binaryData, false));
> }
> {code}
> This will fix the following tests ggregory added a few minutes ago:
>         //assertEquals("Zg==", 
> Base64.encodeBase64String(StringUtils.getBytesUtf8("f")));
>         //assertEquals("Zm8=", 
> Base64.encodeBase64String(StringUtils.getBytesUtf8("fo")));
>         //assertEquals("Zm9v", 
> Base64.encodeBase64String(StringUtils.getBytesUtf8("foo")));
>         //assertEquals("Zm9vYg==", 
> Base64.encodeBase64String(StringUtils.getBytesUtf8("foob")));
>         //assertEquals("Zm9vYmE=", 
> Base64.encodeBase64String(StringUtils.getBytesUtf8("fooba")));
>         //assertEquals("Zm9vYmFy", 
> Base64.encodeBase64String(StringUtils.getBytesUtf8("foobar")));
