Q: 

Flex: Converting a GUID to Base64

In Flex, I have a GUID that I receive as input in the following format "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxx" as a string. How would I convert this to a string of Base64 encoded values?

Please note that we have to account for leading zeroes in each section of the GUID, for example, "0091AFBC-8558-482A-9CF6-64F1745E7AC1"

Is this what you're after?

Otherwise roll your own. The concept is fairly simple.

EDIT: Why do you need to convert a printable GUID string into base64? The only reason to use Base64 encoding normally is to make the string 7-bit clean so that it can pass through systems that can't handle 8-bit data properly. e.g. like the old email protocols.The string you have here is 7-bit clean.

@Matt: other reasons for converting Guids to Base64 is aesthetics. People sometimes get scared when they see a Guid, but a smaller set of alpha numerics is okay. Many many publicly facing systems do this. dM0bO5uZzEmzJwIwUOoTRQ is apparently more appealing than 082354EC-CB7A-42B1-8200-12D6A57DC2F0 and smaller too, when transfering a lot of them. ;)

@Chris: I can imagine that if people got scared of a GUID that they'd be no less scared than seeing a bunch of numbers and letters that is only slightly shorter. You can just strip out the dashes and theres is hardly anything in it. Save yourself some coding overhead!

@Matt: The usage of base64 is not an option, as it is due to compatibility with other components of our application which are essentially frozen.
