Question

please show the code how to implement digital signature algorithm in C along with output??

Answer 1

What is a digital signature?

A digital signature refers to a set of algorithms and encryption protections used to determine the authenticity of a document or software.

In simpler terms, a digital signature is a complicated way to verify that a document hasn’t been tampered with during transit between sender and signer.

code to implement Digital signature algorithm(ie encryptiom and decryption in c:

Example:

code for encryption:

  

Now we have to create a text file( name it as ____.txt) in that we have t give some text that you want to encrypt....

And now run the program and give your text file name as input to the program....

Let's see if our encrypted file is created or not........

In above image we can able to see our encrypted text file. Then if you again convert this Text in to decryption Program copy the same code and maKe small changes in that code...

  ​​​​​Mention decrypt in our console output:

Then finally you are able to see your decrypted original text...
