b64: Base-64 Encoding Library - Synesis Software - C/C++ Software Libraries Resource Site

Updated: 11th October 2019

b64: Base-64 Encoding Library (C library with C++ mapping; Platform-independent)

b64 is a very small and simple library that provides Base-64 encoding and decoding, according to RFC-1113, in C and C++.

The b64 core library is a pure standalone component:

It has zero dependencies on any other libraries. (Note: the C++ API depends on the STLSoft libraries.)
It has zero dependencies on any part of the C standard library, except in debug builds (where it depends on strchr() and assert()),
It has zero dependencies on any host operating system facilities.
It does not allocate any memory.

It is released under the BSD license, which basically means its free for any use, but you can't claim it's yours.

Base-64 conversion of binary regions, using b64, is available as part of the distribution of Pantheios, the ultimate C++ diagnostic logging API library.

Latest Documentation

As of version 1.4.3, it is available on GitHub at https://github.com/synesissoftware/b64.
