## 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',

  'Y', 'Z', 'a', 'b', 'c', 'd', 'e', 'f',

  '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);

```
