Hope someone can help or have a free control. I am going to be passing
data from a client computer to a server via a winsock control. I want
to encrypt/decript the contents of the string that is passed back and
forth. Anyone have any ideas?

Hi,
I am writing a Java Chatroom application that will implement
encryption of messages using the RSA algorithm using the BigInteger
class. It uses socket connections to exchange messages.
I have managed to generated the Private and Public keys and
exchanged public keys and modulus between the clients and server.
Please could someone advise me how encrypt a short message, pass the
encrypted message across a socket connection and then...

I have no background in encryption, so I'm working with samples I've found
in various places and patching them together. I know Blowfish can use a 56
byte key. The version of this program in Perl has no problem with a 56
byte key, but this Java version has problems if I use a key that is any
length other than 8 bytes. Is there something I can do to enable 56 byte
keys and vectors? Here's what I'm doing:

I was in need of an encryption algorithm to the following requirements:
1) Must be capable of encrypting strings to a byte array, and decyrpting
back again to the same string
2) Must have the same algorithm work with strings that may or may not be
unicode
3) Number of bytes back must either be <= number of _TCHARs in *
sizeof(_TCHAR), or the relation between output size and input size can be
calculated simply. Has to take into account the...

Dear all,
I would like to encrypt a large amount of data by using public/private keys,
but I read on MSDN:
"Symmetric encryption is performed on streams and is therefore useful to
encrypt large amounts of data. Asymmetric encryption is performed on a small
number of bytes and is therefore only useful for small amounts of data."
There is not possibility to do it? I have tried to encrypt a 300kB file by
RSA Algorithm, but I received...

I've written a simple program to do XOR encryption as my first foray
into understanding how encryption works. The code compiles fine, however
it segmentation faults on every run. using gdb to debug it let me
narrow the problem down to the Cipher function I think it faults at line
84 or 85. The program makes it's first read/cipher/write pass without
issue but the second pass kills it. Using gdb to print the variables
left showed me the...

I’m trying to encrypt and decrypt a file in vb.net. I am using the
TripleDESCryptoServiceProvider encryption found in
System.Security.Cryptography. Below is the code for my Encrypt and Decrypt
functions.
While my functions read and write files the encryption/decryption is not
working properly. My test file has an original length of 66,048 bytes. My
encrypted file ends up with 66,056 bytes … 8 bytes more than my original.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
