Digital signature

The digital signature, based on the SHA-256 algorithm which we use, is the electronic equivalent of the written signature and it bears the same legal value.
When linked to a digital document, it guarantees its integrity, autentication and non-repudiation.
Benefits for the customer:
  1.  The digital signature has the same legal value as the written signature. Digital documents have an added value compared to signed paper documents, due to improved safety and anti-forgery systems. 
  2. The test report in pdf format has the highest visual quality, both on screen and in print. 
  3. The customer can at any time produce legally valid copies of the test report; therefore he/she can circulate and distribute the original document without making request to CATAS, thus avoiding additional costs and delays.
  4. The handling, control and sending process of electronic documents is much faster than for hardcopies. 
  5. Electronic documents can be conveniently stored by means of informative systems.
When the customer chooses to receive the test reports in PDF format with digital signature, he/she will not be able to receive hardcopies with hand signature as well.
The informative system is designed so as to manage only one type of signature procedure, either on hardcopies or digital, as preferred by the customer, and not both.
All test reports are stored at CATAS for 10 years.
Signature and timestamp certificates “Infocamere” are automatically downloaded with the latest versions of Acrobat Reader. With former versions, when certificates are not recognised, the attached files must be uploaded manually.
It is advisable not to upload signature certificates with the oldest versions of Acrobat Reader, because this will sensibly slow down the opening of PDF files with digital signature. Uploading of certificates should be done only when required for legal reasons.
