What is firma digital signature? Digital signature is the result of an IT program based on encryption technology, which allows you to correlate binary numbers (signatures) inseparably with an IT document or another set of bit that represents facts, behaviors or data related to law. In various situations such as signing contracts, statements or administrative actions by the public and private sectors, the electronic file is granted legal effect. It is not a "simple" electronic signature, it is actually based on a specific type of the above encryption key mechanism. The digital management code (Article 24, Legislative Ordinance 82/2005) has been defined.
Digital signatures must uniquely involve a single topic and additional or associated documents or sets of documents. The paste of digital signatures is integrated and replaces the pasting of any kind of seals, punches, seals, marks and trademarks for any purpose required by the current legislation. Simply put, digital signature is an electronic signature that ensures the authenticity, integration, reliability and legal validity of documents by meeting particularly strict relevant requirements. It has the same value as handwritten signatures (a feature that other types of electronic signatures do not have).
Digital signature is a tool that allows citizens, professionals and businesses to sign documents and convert them into documents of legal value. It is the result of an IT program based on the concept of:
- Authenticity to ensure and guarantee that the person who signed the document is also responsible for its content,
- Integrity, used to demonstrate the conditions that it has never been modified from the moment it was signed to use,
- Undeniable, because those who sign the document through electronic signature cannot deny it.
Therefore, in a digital signature system, each holder is assigned a pair of keys (two binary numbers of equal length, in the prior art, at least 2048 bits). The assignment is performed by an institution-qualified person (verifier) - in Italy by the Italian digital agency - issuing digital certificate for the benefit of the holder , linking a 2048-bit binary number with its identity. This can reliably identify the signature requester.
So how to get a digital signature?
Digital signatures are obtained from trust service providers in a series of trust lists managed by various European member states. There are several digital signature products, which usually consist of a device (usually a smart card) and a device for reading a smart card that contains an updated digital signature certificate. In addition, for several years, a kit containing a USB memory stick with a digital signature certificate can also be found on the market (usually inserting a sim card and then inserting an memory stick . Finally, with the help of a cloud solution, you can use a remote digital signature device to sign documents, or even sign a large number of signatures. They operate through virtual signature devices and can only be accessed by "secure" access to the system and physical devices. These physical devices use the one-time password (similar to the password used by banks) or a smartphone application or text message to provide a one-time password.
is now popular now that you don't need a device to sign directly remotely. I bought this one, and it's easy to operate on your phone, which is very convenient. Electronic signatures are convenient for online offices, which can really optimize a lot of work. If you need it, you can buy it.
