Many people make the mistake of thinking that digital signature software and electronic signature software are the same, but there are some differences between them. While the second contains only an electronic image attached to the data, the digital signature software has a more complex technology, which makes it more suitable for safety.

Digital signatures are the result of the PKI (public-key infrastructure) cryptographic operation. Basically, it is a mathematical scheme used to demonstrate the authenticity of your message or document. In general, it has three components: a key generation algorithm, a signing algorithm, and a signature verifying algorithm.

The digital signature is a growing feature used more and more by big companies in order to be able to work faster, streamline their time, and to save the money spent on the couriers. Security is also very important, so the majority of companies are using a 256-bit SSL encryption. Moreover, the software uses your computer camera to take a photo and place it alongside the signature.
