Using Crypto-C
Algorithms in Crypto-C
Whatever algorithm Crypto-C performs, it does so from an algorithm object. An
algorithm object is used to hold information about an algorithm’s parameters and to
keep a context during cryptographic operations.
To build an algorithm object, create an empty object with
B_CreateAlgorithmObject.
Then, use
B_SetAlgorithmInfo to fill the object with the information necessary to
distinguish it as an object performing the desired operation. The information for
B_SetAlgorithmInfo consists of two elements: an Algorithm Info Type, or AI, and its
specific accompanying
info
. This chapter gives a brief summary of the AIs
categorized by function.
Chapter 2 of the Reference Manual gives a complete listing of AIs in alphabetical order.
Each entry in the Reference Manual contains a description of information that must
accompany the AI, including keys and algorithm methods.
