RIM Cryptographic API

The RIM® Cryptographic API that is on a BlackBerry® device and in the BlackBerry® Java® Development Environment consists

of a Java interface that includes an encryption algorithm, a key agreement scheme, a signature scheme algorithm, a key generation

algorithm, a message authentication code, cipher suites, a message digest, and a hash code.

A developer can use the BlackBerry JDE to access the RIM Cryptographic API to create an application that can run on the

BlackBerry device. The developer is not required to change or access the encryption code directly because all calls to the native

C++ encryption code are sent through the Java code.

Research In Motion uses code signing to authorize and authenticate an application and permit it to run on the BlackBerry device.

Code signing is also used to control the ability of the application to access the RIM Cryptographic API.

Symmetric block algorithms that the RIM Cryptographic API supports

Symmetric block algorithms use PKCS #5 for padding. The RIM® Cryptographic API supports the CBC, CFB, ECB, OFB, and X

modes for all algorithms. The RIM Cryptographic API implements the modes separately from the symmetric block algorithms.
