But what exactly do you want to know? If you can use SSL and
Blowfish?
It does not appear in http://www.openssl.org/docs/apps/ciphers.html.
Yes the web site and the book about the OpenSSL is outdated.
Does TLS spec nowadays defines a
So I need a high performance solution that can handle many connections
with little server load.
1. SSL is a good solution but is not high performance - it's more
suitable for encryption of a web page. When establishing connection more
that 100 connections are used to perform the SSL

What is the purpose of the project?
This is a open source project - I need a way to monitor a
huge number of servers - monitor CPU load, RAM load, HDD

Why not using http://www.nagios.org/?

If I decide to go with openssl and blowfish what are the
potential threats?
Yes, heaps of.
You might consider asking more detailed.
Is there another security mechanism that I can use with blowfish?
Of course...

The encrypted output is not a NULL terminated string so strlen will not work.
EVP_DecryptUpdate(amp;ctx, (unsigned char *)plaintextz, amp;out_len,

Use the length output from the encryption part.
Thank you very much
Hi,
What protocol are you using?
What I mean is application layer protocol. But since in your example, you're
using your own protocol,
why not send both length and data.
Example.
4 byte len field0..2^32-1 data field
Then in you receiving end, do recv 4 bytes, get length, and recv until
received

Don't you know how much data you've read that you're about to decrypt?
in your code template, you showed the sendign routine doing...
nread = recv(sock, buffer, 25, 0);
isn't the recieving routine doing somethign similar? well, nread would
be the length you need, no?

Hi,
I'm trying to code a C program that can convert very big number of characters.
The problem is that there is an error in decryption.
This is the code:

#include

Thank you very much for the reply. The problem is that the encryption

size of the encrypted message using language function like strlen(). Is
there other solution?
