SHA512_Update

void SHA512_Update( [ in,out ]SHA512_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(512) 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 SHA512_Update, call SHA512_Final or SHA512_FinalHex.

Note. Before the first call to SHA512_Update, SHA512_UpdateStr, SHA512_Final or SHA512_FinalHex functions, the context must be initialized with SHA512_Init.

VB Example

See the example for SHA512_Final.
