Hi,

I know Jakarta commons has a Base 64 encoding. But it does not supports a
'modified Base64 for URL'. Can you please tell me if there is any Java library which supports the base 64 encoding for URL?

From here:
http://en.wikipedia.org/wiki/Base64

For this reason, a modified Base64 for URL variant exists, where no
padding '=' will be used, and the '+' and '/' characters of standard
Base64 are respectively replaced by '*' and '-', so that using URL
encoders/decoders is no longer necessary and has no impact on the
length of the encoded value, leaving the same encoded form intact for
use in relational databases, web forms, and object identifiers in gen


Thank you.

I haven't seen one myself, but I have to say that the reason given in that Wikipedia article for the existence of that modified encoding doesn't apply in the Java world. It doesn't matter that text strings being put into databases might contain '%' characters because using a PreparedStatement eliminates the possibility of the sort of problem mentioned in the article.

So I don't think you actually need that algorithm if you're working in Java.
