Q: What is the difference between digital signatures, electronic signatures, and digital certificates? A: Digital signatures are numbers that are calculated using an algorithm for the contents of a file. When this file is sent electronically, the number is appended to the back. When the receiving program receives a digitally signed file, it computes a number using the same algorithm, if the number does not match the digital signature, indicating that the file may have been modified during transmission (possibly by a man-in-the-middle attack). It does not show where content is modified, only whether the content is the same or different from the original send. Electronic signatures are basically the hands used in legal documents ...
