That is an excellent article and I have used it but sometimes even when I have a 8 char string I get the invalid password length error so you may have Edit: Regarding problem with ToBase64String and QueryString: If you do your own QueryString parsing then you need to make sure you only Split on the first =-sign.

I need to encrypt more bytes in the first place. Code public MemoryStream EncrypteBytes(Stream inputStream, string passPhrase, string saltValue) { RijndaelManaged RijndaelCipher = new RijndaelManaged(); RijndaelCipher.Padding = PaddingMode.PKCS7; RijndaelCipher.Mode = CipherMode.CBC; byte[] salt = Encoding.ASCII.GetBytes(saltValue); PasswordDeriveBytes password = new PasswordDeriveBytes(passPhrase, salt, I could be using it incorrectly so if anyone is certain (code snippet that functions please) that it does not result in an exception with an incorrect password then the question Rijndaelmanaged Default Padding Why do languages require parenthesis around expressions when used with "if" and "while"?

I couldn't reproduce the error you describe, suggesting the issue lies in the code you haven't shown. Now on reading I get that error even with the correct password but the data has been decrypted correctly.

It's difficult to see what could be responsible though as all the variables are declared within the function. Can anyone tell me what I can do to solve this issue please.

Alternatively, in your case, I would suggest making sure that you create and dispose an instance of RijndaelManagedTransform for each encryption and decryption operation, initialising it with the key and vector. http://amigasuperbit.com/padding-is/padding-is-invalid-and-cannot-be-removed-vb-net.html This content, along with any associated source code and files, is licensed under The Code Project Open License (CPOL) Top Experts Last 24hrsThis month OriginalGriff 200 Peter Leow 195 John Why is (a % 256) different than (a & 0xFF)?

so it is well possible that wrong keys could not be detected before end of decryption (at dispose time I would guess) what would explain the behavior.

They need to be the same for both encryption and decryption. So I would double check all your keys. I think there is a bug in KeySize property.)
