Steganos LockNote - Version 1.0.1 This open source software enables users to quickly and easily protect confidential notes, passwords, addresses, phone numbers or other sensitive information. LockNote looks and acts like a normal text file; however, it can only be opened with a password chosen by the user. The encrypted memo can be saved to a USB stick and used while on the road or on another PC. Like all other Steganos encryption products, LockNote employs 256-bit AES encryption.
