SHA256_Update

void SHA256_Update( [ in,out ]SHA256_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-2(256) 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 SHA256_Update, call SHA256_Final or SHA256_FinalHex.

Note. Before the first call to SHA256_Update, SHA256_UpdateStr, SHA256_Final or SHA256_FinalHex functions, the context must be initialized with SHA256_Init.

VB Example

See the example for SHA256_Final.
