    Exclamation client/server encrypted transfer

    Hello,

    I've made a serverapp wich uploads an encrypted file every 30 seconds or so, for wich I use this class (Rijndael) to encrypt the data. The meaning is that the data can only be viewed with my clientapp.

    My clientapp downloads the file every 30 seconds, decrypts it and shows the decrypted data. But when I was watching I/O time and CPU usage of my program with Process Explorer, I could read out the password wich is used to decrypt the data. (Properties of the exe»strings) So my implementation isn't good.

    I use the class as
    Code:
    CryptoLib.Decrypt("MyEncryptedText", "MyPassWord", "MySaltValue", "HashAlgorithm", 3, "MyInitVector", 256)
    But I can find this strings without a problem in Process Explorer. That wasn't the meaning

    Do you have tips how I can solve this problem?

    With kind regards,
    Thomas
