Hash Component Overview

📖 Introduction

cCryptoHash is a Windows CryptoAPI-based hash computation class that supports multiple hash algorithms including MD5, SHA1, SHA256, SHA384, and SHA512.

✨ Key Features

Feature	Description
Multiple Algorithms	MD5, SHA1, SHA256, SHA384, SHA512
Multiple Inputs	Supports strings, byte arrays, files
Multiple Outputs	Supports Hex strings, Base64, byte arrays
Chainable API	Fluent API design with method chaining
Auto CSP Selection	Automatically selects appropriate cryptographic service provider
Encoding Support	Supports UTF-8 and ANSI encoding

🚀 Quick Start

Create Instance

Dim Hash As New cCryptoHash

Simple Hash Computation

' Compute string hash (default SHA256)
Dim hashValue As String
hashValue = Hash.ComputeHash("Hello World")
Debug.Print hashValue  ' 64-character hex string

Chainable Call

' Use chainable call
Dim result As String
result = Hash.Mode(HASH_ALG_SHA256) _
            .DataString("Hello World") _
            .ReturnHex()

Compute File Hash

' Compute file SHA256
Dim fileHash As String
fileHash = Hash.ComputeFileHash("C:\data.txt")

📋 Supported Algorithms

Algorithm	Enum Value	Output Length	Description
MD5	HASH_ALG_MD5	128 bit (32 hex)	Not recommended for security
SHA1	HASH_ALG_SHA1	160 bit (40 hex)	Being deprecated
SHA256	HASH_ALG_SHA256	256 bit (64 hex)	Recommended
SHA384	HASH_ALG_SHA384	384 bit (96 hex)	High security
SHA512	HASH_ALG_SHA512	512 bit (128 hex)	Highest security
