This no-frills encryption utility quickly secures files, but the limited feature set will disappoint advanced users. DataSafe's interface is no beauty, though it's simple enough for novices to understand and operate. The dual-pane main window makes it easy to browse for files to encrypt. The program's 32-bit encryption algorithm won't stop determined hackers but is strong enough for small-office and home use. The program demonstrates speedy performance when operating on a large group of files, but encrypting a 1GB file took considerable time to complete. It's important to note that DataSafe can't create self-decrypting executables and doesn't include a file-shredding tool to securely erase originals. Its feature set isn't as robust as similar programs', but this freeware works fine for any user who performs occasional batch encryption.

From Cascade Research:
File encryption program featuring a new scalable, ultra-fast stream cipher. The encryption speed is comparable to SEAL 3.0. But unlike SEAL this algorithm will run twice as fast on a 64-bit machine. We offer a $1000 reward to the first person who can break it.
