I have a problem witht the SSL_accept / handshake which i could not
resolve with the help of the net / colleagues / time.
Having written a small server / client, it gives the following output

Hi
This may be a double post if it is I apologise (I think I may have
posted this before I was authorised by majordomo).
I have started using encryption and thought I would try this out. My
question(s) are as follows - please be gentle

Help please.
I have a program/parent thread that launches 4 child threads. It's a
Win32 application that has to be linked using the /MT VC compiler option
for reasons other than OpenSSL. The parent thread calls the following
OpenSSL calls.
CRYPTO_malloc_init();
SSL_library_init();
Hello,
1: How is the IV handled in (AES) encryption - I can see supplying an initial
vector is good but it also appears this should change with every
encryption (if you like). So does a user have to know this + key ?
IV is used by encryption mode (like CBC) not by encryption algorithm like AES.
Hello,
In any case, does it hurt anything if I try to implement these two
OpenSSL functions anyway?
I think that no.
And, if it's quick and easy to do, can someone sent code snippets of
implementations of these two functions?
You may use something like that:

--Actually, in AES in CBC mode, the ciphertext is dependent on the already
computed ciphertext block. That is, CT for block k is dependent on CT of
block k-1 and plain text for block k. (How it is dependent is a complex
maths). But how do you know the

help me. I was just reading some docs there pointing me to this but you
have saved me a good few hours.
I will search out info for python info on PBKDF2 many thanks for that.

Hello,
Just quickly though in point 3 does that mean I should use ECB mode
or not if I am going to split the file and send two parts to different
locations?
Of course not, look at:

(link posted to that list before).

I am more educated than I was 10 mins ago. I hope other folk read this

Hello once again,
here is my cut-down code as well as output.
Basically, the server fails after the line // FAILS!!! without the
client even connecting to it.
Does anybody have an idea ?
Many thanks

please let me know
create a public salt (anyone can see this and will) of X length (128bits)
take sha512 hash of file to be encryted (and keep it)

the others) are NULL.
When I call BIO_new() it does an

the user can access and see only its account, and they are supposed to

hi ,
I want to decrypt using 3DES and want to use the EVP api.
Here's what i'm doing, it will be nice someone could validate if my approach
is correct. here's the code that i have come up with...
int 3desDecrypt(unsigned char * pEncData, int pDataSize)
{
int dec_data_size = 0;
