SHA1_Update

void SHA1_Update( [ in,out ]SHA1_Context* pContext, [ in , size_is( nSrcLength ) ] const void* pSrc, [ in ] int nSrcLength );

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 continuous memory block with which to update the context.

 nSrcLength

    [in] Length in bytes of the memory block.

Remarks

Updates (based on SHA-1 hash algorithm) the pContext context with the pSrc memory block. Call this function for each continuous memory block of the data for which the message digest is calculated. To retrieve the digest after using SHA1_Update, call SHA1_Final or SHA1_FinalHex.

Note. Before the first call to SHA1_Update, SHA1_UpdateStr, SHA1_Final or SHA1_FinalHex functions, the context must be initialized with SHA1_Init.

VB Example

See the example for SHA1_Final.
