Data Encodings This book is a collection of tutorial notes and example codes written by the author while he was learning different data encoding algorithms. Topics include introduction of data encoding algorithms: Base32, Base64, UUEncode; Base64 Encoding Algorithm with W3C Implementation; Base64 Encoding tools and API in Java, Python, PHP and Perl; Base67URL Encoding to be URL and Filename safe; Base32 Encoding Algorithm with Java, PHP and C++ Implementations; URI/URL encoding with Java and PHP example programs; application/x-www-form-urlencoded encoding with Java and PHP example programs; UUEncode Encoding Algorithm with Sun Implementation. Updated in 2023 (Version v5.23) with minor changes.
