Minimal music . Digital certificates serve the purpose of validating the data sent to ensure that it has not been tampered with. . It uses a method called ‘hashing’ to do this. This hash is a unique string created from the data. It is then encrypted with the sender’s private key before being sent.. Vanessa Teague, March 2017. vjteague@unimelb.edu.au. Short bio.
