Datum Locker allows you to juggle your workstation notes and login accounts safely as behind the scenes a lock exists on this data using cryptography as it is fundamentally for your eyes only.

Datum Locker assists safe record keeping of account credentials and note taking which are deemed sensitive. Its strength comes from the use of Nullox's linearistic distance cryptographic (LDC) algorithm to securely store your data on disk thereby presenting an intruder with random symbols due to the omittance of a valid key. Datum Locker operates on a timer thus monitoring when the application...
