When in doubt, use grep :-)
unsigned char md5Hash;
cipher = purple_ciphers_find_cipher("md5");
context = purple_cipher_context_new(cipher, NULL);
purple_cipher_context_append(context, (guchar *)input,
sizeof(productKey) - 1);
purple_cipher_context_digest(context, sizeof(md5Hash), md5Hash,

I have no idea, but we use it all over so it should be safe.
