Ultimate Security Encryption SC4™
Need a simple but strong freeware
encryption utility? Ultimate Security Encryption SC4™ (USE-SC4)
uses a strong encryption Stream Cipher based on the RC4 algorithm. It
utilizes a 256-byte key with byte-oriented operations. Default hashing
functions employ SHA, and the program can also be configured for MD5
hashes. Advanced salt(IV) and algorithm priming implementations protect
against repeated passwords and 'weak key' vunerabilities. The cipher
code has been optimized and will run very quickly on most hardware. The
RC4 algorithm has been scrutinized by independent analysts and is
considered secure. USE-SC4 also detects file tampering and warns
Secure & reliable encryption.
Easy to use.
Detects file tampering.
Fast algorithm (1.5Mb/Sec on
Celeron™ 333Mhz w/64Mb RAM).
Encrypt & decrypt multiple
files in one operation.

System Requirements and
is a 32-bit program which works with Windows95™, Windows98™, or
WindowsNT™ & 2000/2003. Program should also work with Server
2008 and Vista. For good performance we suggest a Pentium®
-class processor or better with 32mb of RAM or more. Minimum
requirements are actually substantially lower, but performance may
