Encryption and Decryption of Image file using AES and RSA

Question

Can anyone help me with Encryption and Decryption of Image,Text,PDF,Word files using RSA algorithm with time and memory usage in asp.net c#??

Marvin Reid · Answer

You can try using the LEADDocument class from the LEADTOOLS SDK as it supports both the loading of encrypted files and decryption. The PDFSecurityOptions class will let you apply encryption to your PDF documents. When loading in the document that is encrypted, you can add a check in your application to handle the loading and decrypting of your files: using (var document = DocumentFactory.LoadFromFile(Path.Combine(ImagesPath.Path, "Protected.pdf"), options)) { if (document.IsEncrypted && !document.IsDecrypted) { Console.WriteLine("Encrypted Document, decrypting it..."); // Decrypt it now document.Decrypt("password"); } } https://www.leadtools.com/help/sdk/v21/dh/dox/leaddocument-isencrypted.html https://www.leadtools.com/help/sdk/v21/dh/to/loading-encrypted-files-using-the-document-library.html https://www.leadtools.com/help/sdk/v21/dh/dox/loaddocumentoptions-password.html https://www.leadtools.com/help/sdk/v21/dh/pdf/pdfsecurityoptions.html

I am implemeting a project... The zip file which I have shared is through aes algorithm encryption and decryption of image... I want to next implement is that "through rsa algorithm encryption and decryption of image or any file using asp.net" ... Plz help me to implement the idea by sharing code or creating website or links .... "Now I want is rsa Encryption and decryption of image or any file" Yes u r getting my point now how it works internal @jignesh kumar Plz give me a solution I m searching frm more than 7 days not getting still is it so tough or I couldn't find m so worried abut my project https://www.youtube.com/watch?v=HWNcfxUadUs this is link which I am inventing also the part of graph
