0.3.0
The Calypso Crypto Asymmetric API is the internal interface between the Calypso Card library and the crypto modules that perform the asymmetric computations of a PKI secure session.
The complete, versioned reference — types, operations, behaviour, diagrams and constraints — is maintained in the Calypso Crypto Asymmetric API specification. This page is only a short overview.
What it provides
An SPI, not a service — the API consists of the interfaces a crypto module implements, and that the Calypso card transaction calls during a PKI secure session.
Certificates — card and certification authority certificates, with their parsers, are supplied by the implementation and consumed when the card is authenticated.
Session cryptography — initialisation of the session context and verification of the card signature.
