Just to add to your options ;-), here's another suggestion: convert the byte[] to an integer (store it in a BigInteger). BigInteger can give you a string representation in whatever base you want. Base 10 would give you a purely numeric but rather long string; base 16 (hex) would be more compact. But you can go all the way up to base 62 (same principle as hex notation, but using [a-cA-Z0-9]).
I think that probably gives you the most compact URL-safe representation,
though I'm not sure. Compare URL-encoded Base64 vs. this technique and see
which works best for you.

Thanks the base64 combined with URLEncoder should work great.

Subject: Re: How to encode byte array as url parameter
Base64 will not work, because its charset includes + and / ASCII
characters. So you might write something like strToHex() (or whatever
its name is), for example see Cryptix library, Hex utility class. Or
you can just use that class directly.
On the other hand, you may use Base64, and then URLEncoder.encode().

Hi I am wondering how I can take a byte[] and use it as a URL parameter?
I
have tried converting it to a string using varying character sets, but
when
I call string.getbytes I never get back my original array. Any help
would
be greatly appreciated.
Thanks
