To protect your data even if it falls into the wrong hands, SecureZIP enables you to encrypt it using the same strong encryption that banks and the federal government use. You can use either digital certificates or pass phrases to apply strong encryption.

Digital certificates have the advantage that they enable you to encrypt just for the people you want to be able to view your files. Similarly, other people can use your certificate to encrypt messages and files specifically for you. SecureZIP accesses your certificate and decrypts for you transparently. You can also use your certificate to sign files. When you attach your digital signature, you let people know the message or file really comes from you.

SecureZIP available free for personal use (SecureZIP Express), it contains all the features of SecureZIP except two: Office Integration and Outlook attachment. You required registering to get a free serial number while installing SecureZIP Express.
