Public Functions
`SFCError`	GetOperationContext( `SFBBNConstRef` inBN , `SFBBNSmpPtr` outBN ) This method returns an SFBBN object that functions both to represent a stored big number and a context with which to perform arithmetic operations.
static `SFBBNEngSmp`	NewInstance( `SFCErrorPtr` exception = null ) Create a new SFBBNEng instance.
static `SFBBNEngSmp`	NewInstance( `AEECLSID` id , `SFCErrorPtr` exception = null ) Create a new SFBBNEng instance.
`SFCError`	SetParam( `SInt32` id , `VoidConstPtr` data , `UInt32` length ) (inherits from SFBParameters) This method sets a parameter value.
`SFCError`	SetParam( `SInt32` id , `SFXBufferConstRef` data ) (inherits from SFBParameters) This method sets a parameter value.
`SFCError`	SetParam( `SInt32` id , `SFXAnsiStringConstRef` data ) (inherits from SFBParameters) This method sets a parameter value.

SFBBNEng::GetOperationContext

This method returns an SFBBN object that functions both to represent a stored big number and a context with which to perform arithmetic operations.

[ public ]
SFCError GetOperationContext(
    SFBBNConstRef inBN   // Optional BN object that contains initialization data or NULL. 
    SFBBNSmpPtr outBN    // Pointer to a newly created IBN operation context.  
);

Return value

SUCCESS: OutBN.
AEE_ENOMEMORY: Out of memory
AEE_CRYPT_INVALID_KEY: key is wrong length or otherwise invalid.

Other error codes returned by specific engine implementation.

Description

If inBN is provided (it is not NULL), it is used to initialize the value in the context returned. The value for the new context is obtained by calling SFBBN::Get(inBN).

SFBBNEng::NewInstance

Create a new SFBBNEng instance.

[ public, static ]
SFBBNEngSmp NewInstance(
    SFCErrorPtr exception = null   // Error
);

[ public, static ]
SFBBNEngSmp NewInstance(
    AEECLSID id                    // Class ID
    SFCErrorPtr exception = null   // Error
);
