Communication Security Overview
Secure Sockets Layer Standard
See&Share software complies with the SSL 3.0 standard for secure communications. Data
transmitted in SSL mode is encrypted to prevent a third party from viewing it while it’s in transit
between a client and server. See&Share software has been tested to ensure that the encryption
mechanism and the communication layers conform to the standard.
The SSL standard was originally constructed by Netscape Communications Corporation to provide
secure communications between a Web browser and a Web server. Since its inception, the
standard has been revised several times to strengthen security and fix security holes that existed in
previous versions. Version 3.0 of the standard is mature, well established in the industry and has
remained unchanged since November, 1996.
Software toolkit vendors supply libraries that implement the SSL standard and can be used to build
SSL-capable applications. See&Share software uses a toolkit called OpenSSL to provide SSL
security on both the client and the server. This toolkit implements both the SSL and the Transport
Layer Security (TLS v1) protocols, as well as a full-strength general purpose cryptography library.

Certificates
A certificate is a digitally signed document that serves to validate the sender’s identity. See&Share
software generates a new 256-bit SSL certificate each time the server start.
