Certificate System (CS) is an enterprise software system designed to manage enterprise Public Key Infrastructure (PKI) deployments.

The Token Processing System (TPS) is an optional PKI subsystem that acts as a Registration Authority (RA) for authenticating and processing enrollment requests, PIN reset requests, and formatting requests from the Enterprise Security Client (ESC).

TPS is designed to communicate with tokens that conform to Global Platform’s Open Platform Specification.

TPS communicates over SSL with various PKI backend subsystems (including the Certificate Authority (CA), the Data Recovery Manager (DRM), and the Token Key Service (TKS)) to fulfill the user’s requests.

TPS also interacts with the token database, an LDAP server that stores information about individual tokens.

This client is a test tool that interacts with TPS. It is useful to test TPS server configs without risking an actual smart card.

sudo apt-get -y install pki-tps-client

sudo aptitude install pki-tps-client
