Silver Key - 3.5

Silver Key is a program that encrypts files or folders, and produces self-extracting encrypted parcels, which can be sent over the Internet. Silver Key does not require your correspondent to have any cryptographic software installed. The only thing the recipient needs to decrypt the data is the right password or key.

When you encrypt a file with Silver Key (dragging it to the Silver Key icon, for example), the program first compresses and encrypts the file, and attaches a small decrypting program to the encrypted file. When your correspondent receives the parcel, he must execute it in order to decrypt the data.
