The architect of electronic signature technologies

Since its foundation, Cryptolog—software provider at the cutting edge in the fields of electronic signature, timestamping and proof management—has invested all its efforts in pursuing a mission that is both technologically and socially significant: the fundamental overhaul of exchanges, promoting the development of paperless solutions with long-term legal proof. Cryptolog is achieving this specifically through the development of a reliable and secure electronic signature that has the same legal status as a handwritten signature.
