Functions
b64_encode
Encodes an unsigned char *
into base64. User is responsible for freeing the
char *
that is returned.
char *b64_encode(const unsigned char *s, size_t sz);
b64_decode
Decodes a base64 encoded set of bytes into an unsigned char *
. User is responsible
for freeing the unsigned char *
that is returned. decode_sz
is an optional argument
in case you need to know the size of the decoded data, otherwise you can just pass NULL
.
unsigned char *b64_decode(const char *s, size_t sz, size_t *decode_sz);
hex_decode
Decodes a string of characters representing hexadecimal bytes into an array of unsigned char
.
For example, converts "DEADBEEF"
into [0xDE, 0xAD, 0xBE, 0xEF]
.
unsigned char *hex_decode(const char *orig, size_t *sz);
// Example
s = hex_decode("DEADBEEF", &s_sz);
unsigned char h[4] = {
0xDE, 0xAD, 0xBE, 0xEF
};
for (size_t i = 0; i < 4; ++i) {
assert(s[i] == h[i]);
}
free(s);
