Digital Signature

The number of transactions concluded online is increasing. The need for digital signature emerges every time there is a need to bind a decision or transaction to a certain person. It is also necessary to ensure data integrity.


In order to create a digital signature, you will use private and public keys that are part of the Public Key Infrastructure. When you create a digital signature certificate, you check the validity and encrypt the data stream. This ensures that no one can alter or tamper with signed documents afterwards.

Any number of documents can be signed at once and without restrictions on format.

Digital signatures are used extensively to provide proof of authenticity and ensure data integrity. They also guarantee non-repudiation of communications and transactions conducted over the Internet.

With the right technology digital signatures are practically fraud proof. After 15+ years since the first issued ID-card in Estonia there has not been a single case of online identity fraud.
