Cryptocat developer Nadim Kobeissi is ready to release a simple solution to deliver strong encryption at the HOPE hacker conference in New York later this month. The encryption program is dubbed as miniLock, which is a free and open-source browser plugin designed to let anyone encrypt and decrypt files in seconds using a drag-and-drop interface. The program relies on asymmetric encryption, just like PGP (Pretty Good Privacy) which requires two separate cryptographic keys for encrypting and decrypting the information.
