Visual Studio throws an exception "BAD DATA" when it tries to close my crypto stream. here's my code snippet of DES decryption. public Byte [] Decrypt (Byte [] cipherData, Byte [] key, Byte [] iv) { MemoryStream ms = new MemoryStream (); DES mDES = DES.Create (); mDES.Key = key; mDES.IV = iv; mDES.Padding = PaddingMode.PKCS7; CryptoStream cs ... WebJun 16, 2024 · rijAlg.BlockSize = m_IV.Length * 8; This is dangerous, as Rijndael accepts different block sizes, while AES doesn't. So if you allow this then you've named your class incorrectly. And again, it's not really needed. You should instead make sure that your IV is always 128 bits if you want AES. black plate rack

If they look to be the same as that used for encryption, then start by looking at your input and the code that processes it, and the output encryption. Check it's length as raw byte data (i.e. before conversion to Base64) - it should be the same or longer than the input file. black plates in bulk
