Release Notes
Web Interface
The LDAP Proxy is a software application designed to seek out and retrieve public X.509 certificates containing public encryption keys. The public encryption key can then be used to encrypt email intended for the person associated with the retrieved certificate.

Client programs such as email utilities (Microsoft Outlook, Mozilla Firebird, Lotus Notes, etc.) and web browsers (Internet Explorer, Netscape & Mozilla browsers, Firefox, etc.) connect to an LDAP Proxy using either the LDAP protocol or HTML via the LDAP Proxy Web Interface.

If found, the encryption key contained in the certificate can be used to encrypt email that can only be decrypted by the holder of the private encryption key held by the person associated with the public certificate.
