b64.c
=====
Base64 encode/decode
## install
```sh
$ clib install jwerle/b64.c
```
## usage
```c
#include <b64/b64.h>
```
or
```c
#include <b64.h>
```
## example
```c
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include "b64.h"
int
main (void) {
unsigned char *str = "brian the monkey and bradley the kinkajou are friends";
char *enc = b64_encode(str, strlen(str));
printf("%s\n", enc); // YnJpYW4gdGhlIG1vbmtleSBhbmQgYnJhZGxleSB0aGUga2lua2Fqb3UgYXJlIGZyaWVuZHM=
char *dec = b64_decode(enc, strlen(enc));
printf("%s\n", dec); // brian the monkey and bradley the kinkajou are friends
free(enc);
free(dec);
return 0;
}
```
## api
Base64 index table
```c
static const char b64_table[] = {
'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H',
'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P',
'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X',

'w', 'x', 'y', 'z', '0', '1', '2', '3',
'4', '5', '6', '7', '8', '9', '+', '/'
};
```
Encode `unsigned char *` source with `size_t` size.
Returns a `char *` base64 encoded string
```c
char *
b64_encode (const unsigned char *, size_t);
```
Decode `char *` source with `size_t` size.
Returns a `unsigned char *` base64 decoded string
```c
unsigned char *
b64_decode (const char *, size_t);
```
