I am decrypting an AES - 256 , apparently 24 byte key length is working but when i am trying 32 byte key it's not. this is how I converting the 32 byte key to byte. public static string DecryptBySymmetricKey(string encryptedText) { if (String.IsNullOrEmpty(encryptedText...
Error: Invalid key length The key must be in base64 format since it will be stored in a Cloud service that only accepts base64 strings. Any help is appreciated. Solution 1: Varying algorithms determine the key length, for instance, aes192 requires 24 bytes, while aes256 requires 32 byte ...

What is the key length and the block size in your code? The RijndaelManaged algorithm supports key lengths of 128, 192, or 256 bits; defaulting to 256 bits. This algorithm supports block sizes of 128, 192, or 256 bits; defaulting to 128 bits (Aes-compatible). ...
