![]() Digital signatures provide source authentication for online documents, messages or records, in a manner analogous to what a signature provides for a paper document. Two cryptographic techniques are used together to produce a digital signature, a cryptographic hash and a public key cryptosystem. The steps for the sender are as follows:
Steps for the receiver are:
If both the hash and the public key system used are secure, and no-one except the sender knows his private key, then the signatures are trustworthy. The use of digital signatures raises legal issues. There is an online reference [1] for laws around the world. References
