 Digital Signature - Communication among attorneys and their colleagues, as well as clients, is often mission-critical. Ensuring that no one else can intercept and read their e-mail is vital. However, equally important is ensuring the integrity of the sender. Sending e-mail under another's identity is remarkably simple and can be done to mislead the recipient. PointClear Mail ensures the sender's identity with the support of 128-bit Digital Signatures. In addition to providing an advanced encryption system which ensures your e-mail messages cannot not be intercepted, PointClear PointClear ensures the sender's authenticity through use of this digital signature.
When installed, a 128-bit unique private key is generated automatically and stored on your computer. This key has dual purposes, message decryption and a digital signature. Everytime you send a secure message, PointClear Mail uses the recipient's public key to encrypt a secure message. Then a digital signature generated from your unique private key is attached to the message. Upon receipt of your message, the receiver's PointClear software uses his private key to decrypt the message and your public key to verify the digital signature, and therefore guarantees the message came from your computer. If the message fails the digital signature phase, the receiver is alerted to this possible fraudulent message. This simple yet powerful method happens for you automatically. |
