The systems and methods provide for configuring and managing resources on a multi-purpose IC card. In one aspect, a user interface (UI) for an application is presented on a display device. A user is enabled via at least one graphical dialog screen of the UI to configure a communicatively coupled IC card. Management of one or more resources on the IC card is facilitated via at least one graphical dialog screen of the UI.

Configuring and managing resources on a multi-purpose integrated circuit card using a personal computer

A computerized system offers a uniform platform for conducting electronic transactions in multiple different environments. The system includes a portable, multi-purpose, integrated circuit (IC) card and complimentary computer software which enables access and management of resources maintained on the IC card. The software runs on a user's personal computer, empowering the user to initialize the IC card, configure the card with the resources that the user wants to maintain on the card, and to manage those resources. The software enables the user to generate private/public key pairs and establish or change passcodes for access to the card resources. The IC card itself provides the electronic vehicle for securely transporting the user's private keys and certificates without exposing them in plaintext form. The IC card is designed with enough processing capabilities to perform rudimentary cryptographic functions so that the private keys may be employed for signing or encryption without ever being released from the card.

A cryptography system architecture provides cryptographic functionality to support an application requiring encryption, decryption, signing, and verification of electronic messages. The cryptography system has a cryptographic application program interface (CAPI) which interfaces with the application to receive requests for cryptographic functions. The cryptographic system further includes at least one cryptography service provider (CSP) that is independent from, but dynamically accessible by, the CAPI. The CSP provides the cryptographic functionality and manages the secret cryptographic keys. In particular, the CSP prevents exposure of the encryption keys in a non-encrypted form to the CAPI or application. The cryptographic system also has a private application program interface (PAPI) to provide direct access between the CSP and the user. The PAPI enables the user to confirm or reject certain requested cryptographic functions, such as digitally signing the messages or exportation of keys.
