Encode64 is available on the Mac App Store!
Encode64 is a handy tiny OS X utility app for software developers to quickly base64- encode/decode any text-based http payload for testing their REST APIs. It is my first published app written in Swift. The app was originally an ad hoc project which my friend asked me to help developing under an hour. I changed the proprietary encoding/decoding engine to base64 encoding. It was a fun challenging project though.
Check it out at its website!
