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

News: 3rd September 2006: Base-64 conversion of binary regions, using b64, is now available as part of the distribution of Pantheios, the ultimate C++ logging API library.

  • Refactored the use of Null Object dummy variables in the core API. All APIs and behaviour remain the same.

28th April 2006 1.1.1 b64-1.1.1.zip (319152 bytes) b64-1.1.1.md5 (34 bytes)
47f7d363e34441764a680f33047f983a 		Upgraded to full RFC-1113 compliance (version 1.0 did not do white-space line-splitting), and now provides flexible behaviour for line-splitting on encoding and invalid-character detection on decoding.
19th June 2005 1.0.1.4 b64-1.0.1.4.zip (197195 bytes) b64-1.0.1.4.md5 (34 bytes)
b2719ef1fb6f0218d133c0cfd6c79b07 		The library is unchanged from 1.0.1.3 The only changes is that the C++ test program has a minor bug fix in the C++ test program, to seed the randomisation from time(NULL), and the C test file has some printf() format specifier casting to ensure compatibility between Win32, Linux and Mac OS-X.
23rd May 2005 1.0.1.3 b64-1.0.1.3.zip (195639 bytes) b64-1.0.1.3.md5 (34 bytes)
a74e3353d0b28431b4d5f90cbf4dee04 		The library is unchanged from 1.0.1.2 The only change is that the C++ test program has a minor bug fix, to use a C++ cast rather than a C-style cast.
22nd March 2005 1.0.1.2 b64-1.0.1.2.zip (194276 bytes) b64-1.0.1.2.md5 (34 bytes)
0ddb4298b284e8b8eb5ccfe50e2f2442 		The library is unchanged from 1.0.1. The only change is that the C++ test program uses the STLSoft memory_mapped_file components (either from UNIXSTL or WinSTL, discriminated by the PlatformSTL headers), available in STLSoft 1.8.3 beta 4 or later (stlsoft.org/downloads.html#stlsoft_1_8_3).
17th February 2005 1.0.1 b64-1.0.1.zip (193818 bytes) b64-1.0.1.md5 (34 bytes)
2bd6bc1e4795a8b0e3202cdd541160ea 		First release.

Includes library source, header files, C & C++ test programs. Makefiles for Borland, Comeau, Digital Mars, GCC, Intel, Metrowerks CodeWarrior, Visual C++ and Open Watcom, for both UNIX and Win32.
