|
## Installation
|
||
|
|
|
||
|
|
Add base64.cpp and base64.hpp to your project folder or library search path, put `#include "base64.hpp"` in your source, and pass base64.cpp to your compiler
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
~~~
|
||
|
|
unsigned char binary[] = {133, 244, 117, 206, 178, 195};
|
||
|
|
unsigned char base64[9];
|
||
|
|
|
||
|
|
unsigned int base64_length = encode_base64(binary, 6, base64);
|
||
|
|
|
||
|
|
printf("%d\n", base64_length); // Prints "8"
|
||
|
|
printf((char *) base64); // Prints "hfR1zrLD"
|
||
|
|

|

|
~~~
|
||
|
|
unsigned char base64[] = "hfR1zrLD";
|
||
|
|
unsigned char binary[6];
|
||
|
|
|
||
|
|
unsigned int binary_length = decode_base64(base64, binary);
|
||
|
|
|
||
|
|
printf("[%d, %d, %d, %d, %d, %d]\n", // Prints "[133, 244, 117, 206, 178, 195]"
|
||
|
|
binary[0], binary[1], binary[2],
|
||
|
|
binary[3], binary[4], binary[5]);
|
||
|
|
printf("%d\n", binary_length); // Prints "6"

## Details
|
||
|
|
|
||
|
|
Uses common web conventions - '+' for 62, '/' for 63, '=' for padding. Note that invalid base64 characters are interpreted as padding.
|
||
|
|
|
||
|
|
Can be compiled as C, uses .*pp extensions because it is usually used in C++ projects and is tested for C++.
