Encryption exception handling

[selfmadecode]

Implement robust error handling during encryption or decryption, including specific exceptions for different error scenarios, and provide meaningful error messages.

example:

try { // encryption or decryption algorithm here } catch (ArgumentNullException ex) { throw new ArgumentException("Invalid parameter. Ensure all parameters are not null.", ex); } catch (Exception ex) { throw new DecryptionException("Decryption failed. See inner exception for details.", ex); }

// catch IV key and secret key exception

`public class EncryptionException : Exception
{
public EncryptionException(string message, Exception innerException) : base(message, innerException)
{
}
}

public class DecryptionException : Exception
{
public DecryptionException(string message, Exception innerException) : base(message, innerException)
{
}
}`
