Then I wanted to store the input file in + encrypted form. OK I pushed BIO_f_cipher to the BIO stack + and everything was OK. BUT if user types wrong password + BIO_f_cipher outputs only garbage and my function crashes. Yes + I can and I should fix my function, but BIO_f_cipher is + easy way to add encryption support to many existing applications + and it's hard to debug and fix them all. + + So I wanted another BIO which would catch the incorrect passwords and + file damages which cause garbage on BIO_f_cipher's output. + + The easy way is to push the BIO_f_md and save the checksum at + the end of the file. However there are several problems with this + approach: + + 1) you must somehow separate checksum from actual data. + 2) you need lot's of memory when reading the file, because you + must read to the end of the file and verify the checksum before + letting the application to read the data. + + BIO_f_reliable tries to solve both problems, so that you can + read and write arbitrary long streams using only fixed amount + of memory. + + BIO_f_reliable splits data stream into blocks. Each block is prefixed + with it's length and suffixed with it's digest. So you need only + several Kbytes of memory to buffer single block before verifying + it's digest. + + BIO_f_reliable goes further and adds several important capabilities: + + 1) the digest of the block is computed over the whole stream + -- so nobody can rearrange the blocks or remove or replace them. + + 2) to detect invalid passwords right at the start BIO_f_reliable + adds special prefix to the stream. In order to avoid known plain-text + attacks this prefix is generated as follows: + + *) digest is initialized with random seed instead of + standardized one. + *) same seed is written to output + *) well-known text is then hashed and the output + of the digest is also written to output. + + reader can now read the seed from stream, hash the same string + and then compare the digest output. + + Bad things: BIO_f_reliable knows what's going on in EVP_Digest. I + initially wrote and tested this code on x86 machine and wrote the + digests out in machine-dependent order :( There are people using + this code and I cannot change this easily without making existing + data files unreadable. + +*/ + +#include <stdio.h> +#include <errno.h> +#include <assert.h> +#include "internal/cryptlib.h" +#include <openssl/buffer.h> +#include "internal/bio.h" +#include <openssl/evp.h> +#include <openssl/rand.h> +#include "internal/evp_int.h" + +static int ok_write(BIO *h, const char *buf, int num);
