MD2_UpdateStr

void MD2_UpdateStr( [ in,out ]MD2_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 MD2 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 MD2_UpdateStr, call MD2_Final or MD2_FinalHex.

Note. Before the first call to MD2_Update, MD2_UpdateStr, MD2_Final or MD2_FinalHex functions, the context must be initialized with MD2_Init.

VB Example

Private Sub MyButton_Click()   
    Dim Context As MD2_Context
    Dim Digest As MD2_Digest
    Dim MyStrData As String
    MyStrData = "Hello World!"
    'Initialize the context
    MD2_Init Context
    'Update the context
    MD2_UpdateStr Context, MyStrData
    'Get the digest
    MD2_Final Context, Digest
    'Show the hexadecimal representation of the digest
    MsgBox QHASH_ConvertToHex(Digest.Value(0), MD2_DIGESTSIZE, True)
End Sub
