Encryption takes place with the encryption keys and the identity of the sender is assured due to the package contents being signed with the private signing key of the sender. All CerTrax certificates are based on the x.509 standard. CerTrax uses the RSA Keon Certificate Server which consists of a key management engine, a certificate engine, an LDAP certificate repository and a certificate revocation database. CerTrax uses SHA-1 to provide package signatures. This means someone cannot figure out your data based on its SHA-1 fingerprint.
Unregistered users have the ability to receive secure deliveries via a secure website.
There is no limit on the file size. The largest file that CerTrax can handle is a function of database allocations. Simultaneous user count is a function of the load balancing appliances and the scalability of N number of application, database, certificate, notification, and web servers. The architecture is designed to easily handle additional user loads. Localization is currently handled within the presentation layer of the CerTrax architecture at one specific client.
