i was very wrong about the above. sorry about confusion.
i was highly confused by the fact BF_encrypt() takes two BF_LONG
(32bit width) as host endian array. this is rather exceptional calling
convension in openssl itself (blowfish, case and idea functions seem to
take host endian array, while others take net endian array).
host endian calling convension effectively forbids us from doing
something like this:
char text[8] = { something };
BF_encrypt(text, key);
i really hope all algorithms under openssl/crypto/* to take a pointer
to octet stream as its argument, like:
void BF_encrypt(data, key)
u_int8_t *data; <---
BF_KEY *key;
and avoid such confusion.
