[jira] Resolved: (MIME4J-67) Base64Encoder fails to encode streams
longer than its buffer size (1024)
[ https://issues.apache.org/jira/browse/MIME4J-67?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Markus Wiederkehr resolved MIME4J-67.
-------------------------------------
Resolution: Fixed
Assignee: Markus Wiederkehr
Resolved by using Base64OutputStream instead of Base64Encoder in CodecUtil.encodeBase64(). Base64OutputStream does not have this issue.

> When encoding streams longer than 1024 bytes the encoder simply concatenate the base64 version of each 1024 chunk and this is wrong. Base64 streams are only concatenable when the original text length was a multiple of 3. Supporting buffer chunks encoding require keeping the last 1-2 bytes in a buffer and eventually convert them to base64 ending sequences only when the stream is closed.
