Delphi: How to calculate the SHA hash of a large file

Question

Hi I need to generate a SHA over a 5 Gig file

Do you know of a non string based Delphi library that can do this ?

Answer 1

I would recommend Wolfgang Ehrhardt's CRC/Hash.

It's fast and "can be compiled with most current Pascal (TP 5/5.5/6, BP 7, VP 2.1, FPC 1.0/2.0/2.2) and Delphi versions (tested with V1 up to V7/9/10)".

I've used it with D11/D12 too.
