Xave is Secure Encrypted Space on your device which allows you to store private and confidential data locally. This allows you to take your private data wherever you go. Furthermore, all files are encrypted at rest on your device instead of the cloud. When the app is not in use, it is protected with several layers of authentication before it can be accessed. Anytime you leave the app, it will require you to re-enter your 4-digit PIN and uses biometric authentication if that feature has been enabled. Xave does not require any personal information. It utilizes our universal 9-digit xID, which can be used across our other Secure and Encrypted apps, such as the xPal Ultra Secure messenger. Xave provides you with more than just a secured local encrypted space on your device. It also allows you to send and receive encrypted files through xPal Secure Messenger, without the need for any additional registration. Peace of mind and control is what Xave is all about it. All your personal data is encrypted at rest and is with you all the time. Xave also provides you the control to add, permanently delete, send, receive, sort, search and browse files such as photos, videos, and other supported files with ease and speed. Creating a Xave space is simple and easy. If you already have an xID from xPal, simply log in with your xID. If you’re a new user, it only takes a few seconds to register. Simply choose a screen name, a 4-Digit PIN, a password and you’re off and running. You can start storing your personal data in your encrypted and secured Xave space. Xave uses a key exchange protocol which combines the Double Ratchet algorithm, PreKeys, triple Elliptic-curve Diffie–Hellman (3-DH) handshake, and Curve25519. xPal also uses AES-256, and HMAC-SHA256 as primitives. Our own patent pending encrypted compression method allows for one of the best and fastest viewing and delivery of large encrypted files. Now you no longer have to worry about your private files being out of your control in the cloud or being accessed without your permission. Welcome to Xave!
