Does a digital signature replace a handwritten one?
In a lot of instances yes. Countries operating on what is called Common Law recognize that if the parties to a contract agreed it would be made in a particular way (say by fax or e-mail) then that was binding. After all, your physical signature as a fax copy is hardly the real thing, but is generally accepted. The same is true of the digital signature. Some countries and regions (the European economic area, the USA, the State of Utah) have laws that specifically recognize the digital signature. At the same time, there are some things that, as yet, are not accepted. The making of a will, for instance, may not be accepted. The transfer of title of land may also be difficult. If you have a specific concern you should consult a properly qualified lawyer in the country in which you wish to use a digital signature. You will find that the common sorts of things you want to do on the Internet, buying software, CDs and so on are fine using the digital signature.
