onSign for Microsoft Outlook 98 and 2000 is a Microsoft Outlook add-on which lets you personalize your electronic communications by securely applying your personal, handwritten signature to your e-mail messages. Whether you are signing an e-mail to a friend, a note to a family member, or an important piece of business correspondence, the program gives you the ability to add a personal touch to your messages. onSign's wizard enables you to quickly generate your personal electronic signature, and bind it to your e-mail messages with a single mouse click. It uses industry standards like RSA and Secure Hash Algorithms (SHA) to bind your signature to the text of the message, making your signature invalid if even one character in the message is changed. Your signature cannot be copied, removed, or altered, giving you the freedom to express your identity in your electronic communications.
