ProCryptum

ProCryptum is an advanced, yet very easy to use application designed for securing sensitive documents and information intended to be transmitted over email or other network including the internet. It mimics a simple email interface with a Plain Text editor and an attachments panel. The attachments panel holds files, much like attachments to an email. Both the text and the attachments are stored in a secure, encrypted and compressed format for easy and safe transmission.

The application uses symmetric key Cryptography meaning the key used to decrypt the information is the same key that was used to Encrypt It. Symmetric key cryptography is very intuitive to a non-technical user, unlike asymmetric key cryptography (the key used to decrypt is different from the key that was used to encrypt), which is equally effective, but often more complex for the user to set up.

ProCryptum was designed to be very easy to use, yet it features industry standard encryption algorithms behind the scenes.
