Characteristics of an Initialization Vector

I'm by no means a cryptography expert, I have been reading a few questions around Stack Overflow and on Wikipedia but nothing is really 'clear cut' in terms of defining an IV and it's usage. Points I have discovered: An IV is pre-pended to a plaintext message in order to strengthen the encryption The IV is truely random Each message h...

C# Can't generate initialization vector IV

Hi, I get the following error when I try to create a IV initialization vector for TripleDES encryptor. Please see the code example: TripleDESCryptoServiceProvider tripDES = new TripleDESCryptoServiceProvider(); byte[] key = Encoding.ASCII.GetBytes("SomeKey132123ABC"); byte[] v4 = key; byte[] connectionString = Encoding.ASCII.GetBytes...

What encryption should be used in encoding and how does it affect key and initialisation vectors?

Hi, I'm getting my head around encryption and how encoding affects generation of the keys and initialization vectors. I'm working with a TripleDESCryptoServiceProvider which requires 24 byte key and 8 byte initialization vector using ASCII encoding. If i decide to use a different encoding , how will this affect generation of the key a...
