AuthenticationCAVVAlgorithm Property

Indicates the algorithm used to generate the AuthenticationCAVV value.

Syntax

• C++
• Objective-C
• C

ANSI (Cross Platform)
char* GetAuthenticationCAVVAlgorithm();

Unicode (Windows)
LPWSTR GetAuthenticationCAVVAlgorithm();

@property (nonatomic,readonly,assign,getter=authenticationCAVVAlgorithm) NSString* authenticationCAVVAlgorithm;
- (NSString*)authenticationCAVVAlgorithm;

#define PID_MPI_AUTHENTICATIONCAVVALGORITHM 3

Default Value

""

Remarks

This property is determined by the Access Control Server (ACS), and is filled after receiving a response to a Payer Authentication Request (PAReq). This property contains the one digit value which indicates the algorithm used by the ACS to generate the Cardholder Authentication Verification Value (CAVV), stored in the AuthenticationCAVV property. Valid algorithms include:

The data contained within this property is only valid if the AuthenticationStatus is "Y" or "A". Additional values may be defined at any time. All user implementations must accept any value for this field.

This property is read-only and not available at design time.
