Credentials Library

This is a fast portable C library which provides both high-level and low-level (cryptographic) credential operations.

API Overview:

• credential.h provides the high-level credential operations with integrated card interaction.

• credential_terminal.h provides the high-level credential operations without card interaction, this allows the developer to handle the communication. (- credential_types.h provides the data types shared by both high-level APIs.)

• credential_crypto.h provides the low-level cryptographic operations.

• credential_card.h provides the low-level APDU processing operations, that is the generation of commands and translation to and from internal data types.
