Class CASN1EncBigInt

class CASN1EncBigInt : public CASN1EncPrimitive;

Description

Class for encoding Big Integer objects only - use CASN1EncInt for TInts.

Derivation

• CBase - Base class for all classes to be instantiated on the heap.

• CASN1EncBase - Base class for all ASN.1 types that we can encode.

• CASN1EncPrimitive - All ASN1 primitive type encoding classes derive from here.

• CASN1EncBigInt - Class for encoding Big Integer objects only - use CASN1EncInt for TInts.

IMPORT_C ~CASN1EncBigInt();

Description

private: virtual void CalculateContentsLengthDER();

Description

Calculates number of octets in DER content encoding. Must set value of the appropriate data member.

private: virtual void WriteContentsDERL(TDes8 &aBuf) const;

Description

Writes DER content encoding into supplied buffer, which is already verified to be big enough. Must be implemented by derived classes.

Parameters

TDes8 &aBuf Buffer to write to.
