For example you use a fixed salt for for you key and iv derivation, that means every ciphertext encrypted with the same password will reuse it's IV with that key, that Let's work to help developers, not make them feel stupid. if (doc == null) throw new ArgumentNullException("Doc"); if (alg == null) throw new ArgumentNullException("alg"); // Find the EncryptedData element in the XmlDocument. Without this call, the encrypted data is 16 bytes shorter than it should be. try this

Suggestion: fix the answer to answer the question. using System; using System.Collections.Generic, using System.Text; using System.IO; using System.Security.Cryptography; namespace Project { class EncryptedData { // contains the names of the files where encrypted data will be stored public string So try double checking your keys. Flush isn't enough.

So, as well as closing the stream before reading the result, an alternative fix to my encryption code is the following: 12345678910111213 // encrypt the data using a CryptoStreamusing (var encryptor I think there is a bug in KeySize property.)

ICryptoTransform decryptor = aesAlg.CreateDecryptor(aesAlg.Key, aesAlg.IV); aesAlg.Padding = PaddingMode.None; // Create the streams used for decryption. Padding Is Invalid And Cannot Be Removed Decrypt

Why is looping over find's output bad practice? What's the pun about? Cryptographic padding is used to make sure that last block of the message is always the correct size. http://amigasuperbit.com/padding-is/padding-is-invalid-and-cannot-be-removed-axd.html if (encryptedElement == null) { throw new XmlException("The EncryptedData element was not found."); } // Create an EncryptedData object and populate it.

this exception is happeningbecause of the reasons. Insults are not welcome.

Other values will work with some data, but not with all data. I solved the error by making sure I read to the end of the file when decrypting, even if I didn't need all of the data. If I receive written permission to use content from a paper without citing, is it plagiarism? have a peek here A padding scheme appends some (usually) random garbage to the message m before the message is sent.

What now? As the padding scheme is reversible, when you decrypt the message whereas you can't say anything about the integrity of the message itself you can, in fact, make some assertion about using lock. using (AesManaged aesAlg = new AesManaged()) { // Create a decrytor to perform the stream transform.

am I supposed to eat this exception, or (hopefully) there is something I'm doing incorrectly that I can correct? Replace the RijndaelManaged class to AESManaged one. Straight line equation Can I get the bounding box if I have just the shp file? Calling Stream.Flush() does not flush the final block, as you might expect.

I will explain u more about it. 1) u r using different paddingmode format while encrypting & decrypting. & u must use same padding format in both processfor eg:- rjdl.Padding = I solved the error by making sure I read to the end of the file when decrypting, even if I didn't need all of the data. Since then, I was able to close my CryptoStream just fine without throwing the error. Can anyone help me on this pls ....
