The way electronic signatures work is in the following manner:

• First of all, the message sender will calculate the Message Digest (MD) of the message. This MD you get by converting message M with a one-way hash function
• Furthermore, encryption occurs on the MD using a private key cryptographic algorithm, such as the RSA algorithm. Well, the result of this encryption is called a digital signature (S).
• Then, a digital signature (S) is placed on the message M
• Then, the message M that you have signed with S will be sent using the communication channel
• When message M has reached the recipient, a verification process will occur as a form of proving the authenticity of the message. Here’s the verification process:

• • The digital signature (S) is decrypted using the public key given to the recipient. Later, this process will produce an MD (Message Digest)
  • Then, the receiver converts M to MD with a one-way hash function
  • This hash is similar to the one used by the sender So, if the result is MD = MD, then the signature received is valid and is from the correct sender
