1) Can I compile Openssl fips 1.2 with VC9 and have it still be validated?
2) Can I compile Openssl fips 1.2 on a win32 environment for x64. In
otherwords, compile x64 on XP Windows and run Vista x64 with the binaries
compiled and still be validated?
3) Is it possible to change the names
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

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.
the ciphertext for 1st block? This is where IV
comes in.

Many thanks for a fantastic explanation and for taking the time to
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
and don't repeat my stupid question. CFB mode for me then (we may
stream the data back a bit at a time).
Again brilliant

Is it possible to do gather writes with OpenSSL? For example, instead of SSL_write(), is there something like SSL_writev()?
When doing SSL_read(), the bytes read have already been unencrypted. Is there a way to figure out how much data was read before decrypting

No. If you're going to use SSL_write, you should gather the data into your
own buffer first.
When doing SSL_read(), the bytes read have already been
to use to determine this info? :)
Thanks,
Ed

Hello,
I've looked around and I'm still a little bit confused about a few
details of Diffie-Hellman. (This is not specific to openssl so feel free
to ignore me :-). First of all, my "experimentations" seem to show that
only the server side needs Diffie-Hellman
