Description

base64 RFC1113 Vanilla ANSI-C Code for a portable stand-alone file encode/decode utility. In 2001, I asked people to 'Help me break it!' Since then, 10+years later, the code remains unbroken and is in wide production use world-wide. It has been ported to all major architectures and been used as a template for ports to different computer and human languages. This is very mature and stable code.

Although this comes from a project that was constrained by export controls and is used in secure systems, it is not security code per-se. I have therefore altered the 'Export Controls' category.

    I had to apply some changes to work on Linux and Windows: The '-' and '+' means line removed and line included. 1. change for unix files. if( blocksout > 0 ) { - fprintf( outfile, "\r\n" ); + fprintf( outfile, "\n" ); } 2. change v = getc( infile ); - if( v != EOF ) { + if( feof( infile ) == 0) { v = ((v < 43 || v > 122) ? 0 : (int) cd64[ v - 43 ]); 3. change in the break position perror( b64_message( B64_FILE_IO_ERROR ) ); retcode = B64_FILE_IO_ERROR; + break; } - break;
