The Directive 99/93/EC of the European Parliament on the Community framework for electronic signatures and Presidential Decree 150/2001 which aligned our national legislation with this Directive, treats directly the advanced electronic (or digital) signatures as handwritten signatures. The advanced electronic (or digital) signatures and digital certificates identity, based on modern technology asymmetric cryptography can guarantee the authentication and integrity of data, identification of transacting the legal commitment of the signatory or otherwise non-repudiation of the transaction while they can offer a credible alternative and the issue of confidentiality of data in the handling and storage. The technology of asymmetric cryptography, based on specific mathematical algorithms (eg. RSA, DSA, etc.), generates random cryptographic key pairs (digital data) which are characterized by two important properties: each key to encrypt digital data that can be decrypted only the other (complementary) key, and is not possible with current technology capabilities, to conclude or recreate a key when you know each other. Still intact are necessary especially with multiple applications open or even unknown recipients, on the existence of a trusted third party entities called Certification Service Provider which also attests to any third recipient of a digital signature. The term electronic certificates, in the broadest sense, means all the evidence found in electronic format and are created either automatically or initiated by a trader when conducting an online transaction. But usually the term refers specifically to digital identity certificates or Public Key Certificate which supports the operation of advanced electronic (or digital) signatures. These certificates are standard electronic certificates issued and signed electronically by a Certification Service Provider in order to certify the possession of this pair (asymmetric) cryptographic key.
