KeyTalk

KeyTalk for Android is designed to work in unison with the KeyTalk server, and allows any valid user to obtain a client certificate for (Single Sign-On) access and digital signing purposes, based on their authentication credentials, optionally in combination with trusted device identification.

KeyTalk for Android embraces all the security features of Android, including the mandatory pin setting on the installed certificates.
As of Android 4.1 the certificate is shared for all your existing apps.

Because KeyTalk issues and automatically (de)installs short lived client certificates the moment your users require it, Admins don't need to do any administration, so no more X.509 certificate revocation List requirements.

Not only will your user certificate credentials be automatically updated with every renewed certificate sent to the user, but also the cryptographic keypair will change each time (up to 4096 bit RSA), ensuring the highest level of cryptology available.
