ZipLock is a tool for protecting sensitive data on your PC. It uses a combination of public-private key encryption and secret key encryption. ZipLock provides a variety of secret key encryption algorithms, including the Advanced Encryption Standard and two of the other finalists for the AES: Serpent and TwoFish. In addition to the extensive encryption support, ZipLock also features comprehensive support for compressing your data. ZipLock allows you to compress and view files using Zip, Jar, Tar, Gzip and BZip2.
Version 2.0 added support for encrypting using third-party public keys, support for signing and verifying files, and support for the BZip2 compression format. A new skinnable look and feel was implemented and a new startup wizard that generates a key pair or utilizes a key pair from an existing keystore was added.
