App: KeyTalk client
Developer: KeyTalk BV
Genres: Business, Productivity

The KeyTalk client app enables native secure email encryption, as well access to Cloud, Hybrid and Local network environments, which have been protected using enforced client certificate authentication.
The KeyTalk client app is designed to work as the device agent of the KeyTalk Certificate and Key Management System (CKMS), and allows any valid user, or machine to obtain a wide range of public or non-public digital certificates (PKI).  A few examples; 
A public certificate coming from a Qualified Trusted Service Provider, for servers these are SSL/TLS certificates, for user devices these are personal certificates used for email signing and encryption (S/MIME) or document signing.
A none public certificate coming from an internal CA source where the personal certificate can be used for secure (Single Sign-On) access and digital signing purposes, based on their authentication credentials, optionally in combination with trusted device identification.
