Dim sb As New Chilkat.StringBuilder

sb.Append("Hello World")

' Hashing algorithms (i.e. digest algorithms) operate on raw bytes.
' Therefore, we must specify the character encoding (utf-8, utf-16, iso-8859-1, etc.) to be used when hashing.


' Get the SHA256 hash in hex
Dim sha256_hex As String = sb.GetHash("sha256","hex","utf-8")
Debug.WriteLine("SHA256: " & sha256_hex)

' Get the SHA384 hash in hex lowercase
Dim sha384_hex As String = sb.GetHash("sha384","hex_lower","utf-8")
Debug.WriteLine("SHA384: " & sha384_hex)

' Get the SHA512 hash in base64
Dim sha512_base64 As String = sb.GetHash("sha512","base64","utf-8")
Debug.WriteLine("SHA512: " & sha512_base64)

' Get the SHA1 hash in hex lowercase
Dim sha1_hex As String = sb.GetHash("sha1","hex_lower","utf-8")
Debug.WriteLine("SHA1: " & sha1_hex)

' Get the CRC8 digest in decimal
Dim crc8_decimal As String = sb.GetHash("crc8","decimal","utf-8")
Debug.WriteLine("CRC8: " & crc8_decimal)
