Subject [jira] Commented: (CODEC-89) new Base64().encode() appends a CRLF, and chunks results into 76 character lines
Date Mon, 23 Nov 2009 03:58:39 GMT

Julius Davies commented on CODEC-89:
------------------------------------

Could we put out a fix as "1.4.1" ?

> The instance encode() method (e.g. new Base64().encode()) appends a CRLF.  Actually it's
fully chunking the output into 76 character lines.  Commons-Codec-1.3 did not do this.  The
static Base64.encodeBase64() method behaves the same in both 1.3 and 1.4, so this problem
only affects the instance encode() method.
