A collection of high performance c-string transformations, frequently 2x faster than standard implementations (if they exist at all).

including

• base64, standard
• base64, web/url safe, with configurable alphabet
• base85 (good for http cookies)
• base16 (hex)
• base2 (ascii binary)
• url escaping
• javascript string escaping
• fast number to string conversion, 4-22x faster than sprintf!
• fast ascii upper/lower case conversion, 2-66x faster than stdlib! (yes, 66x faster)

And it's all wrapped up in a bow for you to use:

• BSD License -- do what you want with it.
• Standard clean ANSI C, will also compile as C99 and C++
• C++ wrappers for std::string
• Standard install: configure && make && make install
• Extensive unit tests provided with >98% coverage.
• Endian safe.
• Performance test framework -- don't take my word, run it your self
• Lots of in-code documentation
