free and fast implementation of a Base64 coder for Java
This is a completely free (as defined by the Free Software Foundation), fast implementation of a Base64 coder for Java developers as replacement for the SUN proprietary library
basE91 is an advanced method for encoding binary data as ASCII characters. It is similar to UUencode or base64, but is more efficient. The overhead produced by basE91 depends on the input data. It amounts at most to 23% and can range down to 14%.
