Visual Basic 6.0

Hash the Contents of a File (SHA256 and other hash algorithms)

See more Encryption Examples

Demonstrates how to hash the contents of a file using SHA256, SHA384, SHA512, MD2, MD5, HAVAL, RIPEMD, etc. Visual Basic 6.0

' This example requires the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

Dim crypt As New ChilkatCrypt2

' Choose the hash algorithm.
' Can be  "sha1", "sha256", "sha384", "sha512", "md2", "md5", "haval", "ripemd128", "ripemd160","ripemd256", or "ripemd320".
crypt.HashAlgorithm = "sha256"

Dim hashBytes() As Byte
hashBytes = crypt.HashFile("qa_data/jpg/starfish.jpg")

' Let's examine the hash as a hex string.
Dim sb As New ChilkatStringBuilder
success = sb.AppendEncoded(hashBytes,"hex")
Debug.Print "SHA256 hash = " & sb.GetAsString()
