API

Base64 index table

    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',
    'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n',
    'o', 'p', 'q', 'r', 's', 't', 'u', 'v',
    'w', 'x', 'y', 'z', '0', '1', '2', '3',
    '4', '5', '6', '7', '8', '9', '+', '/'
    };

char * b64_encode (const unsigned char *, size_t);

    Encode unsigned char * source with size_t size. Returns a char * base64
    encoded string.

unsigned char * b64_decode (const char *, size_t);

    Decode char * source with size_t size. Returns a unsigned char * base64
    decoded string.
