Padding Is Invalid And Cannot Be Removed Formsauthentication.decrypt

May be my answer may guide you to your solution. byte[] bEncrypted = new byte[10000]; int slen = inFile.Read(bEncrypted, 0, 10000); System.IO.MemoryStream inStream = new System.IO.MemoryStream(bEncrypted, 0, slen); CryptoStream cstream = new CryptoStream(inStream, decryptor2, CryptoStreamMode.Read); Tuesday, May 24, 2011 4:00 PM Can anyone help me on this pls ....

You can read or write to/from the crypto stream on either encrypting or decrypting, but one will result in the number of bytes you specify from your source (in my case What happens when a wizard tries to cast a cone of cold through a wall of fire?

Doing AES in both Java and C#, and now don't know why C# complains about Java padding, although both use PKCS#7 –Hoàng Long Mar 3 at 3:03 add a comment| 6 My new theory is to setup a mock domain in my hosts file and change the site binding in IIS to use this new binding on port 80. Information regarding the origin and location of the exception can be identified using the exception stack trace below. 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.

As @NetSquirrel says, you need to explicitly set the padding for both encryption and decryption. Source Error: An unhandled exception was generated during the execution of the current web request. However if you for some reason are using a different set of keys for decryption than used for encryption you will get this error: Padding is invalid and cannot be removed

Not the answer you're looking for?

The problem occurs when Sitecore tries to decrypt the FormsAuthenticationTicket. if (key != null) { key.Clear(); } } } private void Decrypt(XmlDocument doc, SymmetricAlgorithm alg) { // Check the arguments. My code below is where i get the key etc and if the cryptoMode is false it will call the decrypt method, which is where the exception occurs: public void Cryptography(XmlDocument see: http://msdn.microsoft.com/en-us/library/ms998288.aspx -- bruce (sqlwork.com) Rodrigo m.

(Note: I use I have spent over a day trying to figure out why I couldn't decrypt properly and it turned out I was setting the key size after the key in the code. Your Sitecore installation suddently returns an CryptographicException: Padding is invalid and cannot be removed.

Mimsy were the Borogoves - why is "mimsy" an adjective? Finally it occured to me that I had one program which was reading the entire contents of the encrypted file just fine, but the program that didn't read the entire contents

When you update Sitecore, a new key is used for encryption and decryption, hence making the old cookie invalid.

I don't know what steps I did wrong. Do not explicit set the KeySize of algorithm class, left them default. (This is the very important step. I used the Security.Cryptography.Debug interface to trace all parameters used in the encrypt/decrypt methods. Moving that line outside of the using fixed it for me. –cadrell0 Jul 23 '15 at 3:38 add a comment| up vote 19 down vote This exception can be caused by
