Free Encryption Software
We provide free versions of our commercial software for those users who use file encryption only from time to time, and who would rather not pay for a fully featured security solution.
Kryptelite is a free version of Kryptel, a reliable, fast, and easy-to-use file encryption program. While it lacks advanced Kryptel features, it is a great program, which will perfectly suit your needs if your security demands are not very high.

Silver Key Free Edition
Like the commercial editions, free Silver Key creates self-extracting encrypted files, which can be safely sent over the Internet. Your correspondent does not need any cryptographic software in order to decrypt a Silver Key parcel; all he needs is to double-click the file and enter the right password.
See Silver Key edition comparison to make sure it fits your requirements.
