Appendix A: RIM Crypto API Interface

The RIM Crypto API on the BlackBerry device and in the BlackBerry JDE provides developers with a toolkit of
cryptographic algorithms and support tools that they can use to create secure applications for business
connectivity. RIM uses code signing to authorize running secure applications on the BlackBerry device and to
control third-party application access to the RIM Crypto API.
The RIM Crypto API consists of a Java interface and algorithms for the following components:
•
schemes for encryption, key agreements, and signatures
•
a key generation protocol
•
code for message authentication, message digests, and hashes
Developers can use the JDE Java interface to access the RIM Crypto API encryption algorithms and other code to
create simple solutions. Developers do not need to modify or directly access the encryption code because all
calls to the native C++ encryption code are routed through the JDE Java code.
