What are the processes of digital signature?

The steps of digital signature and verification are as follows:

1) The sender applies a hash algorithm to the data and generates a hash value.

2) The sender uses the private key to convert the hash value into a digital signature.

3) The sender sends the data, signature and sender's certificate to the receiver.

4) The receiver applies the hash algorithm to the received data and generates a hash value.

5) The receiver uses the sender's public key and the newly generated hash value to verify the signature.
