Asp.net Cryptographicexception Length Of The Data To Decrypt Is Invalid
I tried searching the web but only found answers to problems that arise when using Encoding when encrypting and decrypting a single string. Welcome to the Coding Forums, the place to chat about anything related to programming and coding languages. If it is the same issue, would you mind discussing this issue in that new thread? I have found that while most strings work with the four symmetric algorithms I have enabled for the class (DES, RC2, Rijndael, and TripleDES), sometimes I receive a cryptographicexception Length of http://wrrd.org/is-invalid/ora-06550-is-invalid.html

Rolling your own security code is almost always a bad idea. Thanks in advance. Length Of The Data To Decrypt Is Invalid C# Specify the size of the key in bytes (instead of bits). Padding Is Invalid And Cannot Be Removed. Block ciphers have a fixed block size they process, and unless you are using a cipher mode that converts the block cipher to a stream cipher, there will be padding that

If during the encryption, a space is part of the encrypted string, it can throw the above error. It takes just 2 minutes to sign up (and it's free!). Insults are not welcome.
Please post a screen shot about the failed request.
Regards. Password creation can be done in several iterations. You will have to read more bytes from the socket than the size of the file permits in order to read the padding. –Jeffrey Hantin Jun 3 '09 at 19:34 No Profanity, Racism, or Prejudice.
this is not "roll your own." Though, there is a good point to be made, that developers need to be careful about how they use encryption. –Cheeso Jun 3 '09 at MemoryStream memoryStream = new MemoryStream(); // Define cryptographic stream (always use Write mode for encryption).
