need base64 encode/decode in c

I need a function to encode base64 and a function to decode base64 string i开发者_运维问答n c. I found http://base64.sourceforge.net/b64.c but the functions work on files, not strings, and add line breaks. I need one that simply encodes/decodes strings. Where can I find such a sourcecode?

Get the functions from libb64.

If you have openssl available to you (which most *nix distros seem to have out-of-the-box these days), it provides robust, well-tested base64 encoding/decoding out of the box. This site has a decent code sample: Howto base64 decode with C/C++ and OpenSSL

When I needed to use Base64 encoding to build an encrypted email server, I decided to build my own implementation.

Currently, it's placed within a C++ class; but I wrote the encoding functions without using any c++ specific code, so you can copy and paste as you please.

This implementation is not approved by any organizations; but it should help you with learning how the algorithm works, while also giving you access to just base64 encoding. IE: no extra libraries get included.

Use as you please. The functions take chars, maps them to an integer via bit-wise operations, and then produces your result.

Currently, there's no newline or carriage return, which specified in the MIME implementation.

If you decide to use the code and find any bugs, let me know through github.
