Speak Freely for Windows
Why encryption?
Why bother with encryption? Privacy! When you talk over a data
network, anybody connected to your network or with access to any of the links
your sound data passes through on its way to a distant Internet site can
potentially eavesdrop on your conversation. Encryption, based on a key known
only to you and person you're talking to, protects against interception by
third parties. No encryption scheme can be absolutely guaranteed to be 100%
secure and even if it were, you'd still be at risk if somebody gained access to
your key. But the encryption offered by Speak Freely, particularly the
IDEA algorithm which is also used by PGP to encrypt message bodies, provides a
great deal of security, indeed better than any generally available digital
cellular telephone.
