CryptosecOpenkeyTSA: (Time Stamping Authority)

Time Stamping Authority, CryptosecOpenkey TSA, aims to generate time stamping to certify, safely and quickly, the exact time when the digital signature process has been carried out.

The Digital Signature ensures who has performed a certain action, but is not valid to certify that the action happen in a certain instant of time. To do this, a Time Stamping Authority such as CryptosecOpenkey TSA is required.

Thanks to this solution, we can affirm and certify that signed electronic documents have existed from a certain time, and that they are valid from that moment.
