TIGER_UpdateStr

void TIGER_UpdateStr( [ in,out ]TIGER_Context* pContext, [ in , string ] unsigned char* pSrc );

Parameters

pContext

    [in/out] A memory buffer that is used as the context.

     Note. All predefined types are specified in the Predefined Types List.

 pSrc

    [in] A null-terminated string with which to update the context.

Remarks

Updates (based on TIGER hash algorithm) the pContext context with the null-terminated string specified by pSrc. Call this function for each null-terminated string for which the message digest is calculated. To retrieve the digest after using TIGER_UpdateStr, call TIGER_Final or TIGER_FinalHex.

Note. Before the first call to TIGER_Update, TIGER_UpdateStr, TIGER_Final or TIGER_FinalHex functions, the context must be initialized with TIGER_Init.

VB Example

Private Sub MyButton_Click()   

    Dim Context As TIGER_Context

    Dim Digest As TIGER_Digest

    Dim MyStrData As String

    MyStrData = "Hello World!"

    'Initialize the context

    TIGER_Init Context

    'Update the context

    TIGER_UpdateStr Context, MyStrData

    'Get the digest

    TIGER_Final Context, Digest

    'Show the hexadecimal representation of the digest

    MsgBox QHASH_ConvertToHex(Digest.Value(0), TIGER_DIGESTSIZE, True)

End Sub
