SPac

SPac combines both compression and encryption into the one product and utilizes a user-friendly interface to make manipulating your secure archives simple. In addition to compression and encryption, SPac has a unique, we think, feature that makes it simple to protect and share sensitive files. Any SPac package can be converted into a self-extracting archive with a difference. The difference with SPac over similar tools is that the recipient of your package does not require their own copy of SPac. They can add, delete, and modify files in the package as well as simply extracting them. By using SPac your sensitive files need never exist permanently on disk, while still allowing trusted friends and associates the ability to modify them. Once the user has supplied the required password, they can modify the files simply by double-clicking on them, the changes will then automatically be encrypted and stored back in the archive, and the working file will be wiped from disk. Encrypt and send files of any type to colleagues via Email (or most other file-based communication software) secure in the knowledge that only the recipient can view the contents of the package. SPac was developed and compiled outside of the USA, has no back doors or escrow keys, and is not subject to US export restrictions. Files are encrypted using the very strong BlowFish (448-bit key) algorithm, and high compression keeps the file size down. SPac is licensed as shareware, the cost of the registered version is $29 and full download size is 1.38 MB. You can download a free version of SPac by following download link at Free Downloads section of this page. SPac is developed or distributed by MCS and is listed under security & privacy encryption tools.
