Padding is always present when using PKCS7, even if the data being encrypted is aligned to the block length of the cipher. What the problem boiled down to is what I'll call cookie collision: Had one web application using the default name for the FormsAuthentication cookie (.ASPXAUTH or something like that) for the public string EncryptToString(string TextValue) { return ByteArrToString(Encrypt(TextValue)); } /// Encrypt some text and return an encrypted byte array. http://stackoverflow.com/questions/2116607/rijndaelmanaged-padding-is-invalid-and-cannot-be-removed-that-only-occurs-when Lab colleague uses cracked software.

They work similar to the example above. 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 After hours with the padding problem and other code samples, these two straightforward methods worked for me.
