(Visual Basic 6.0) HMAC MD5 to Match RFC 2022 Test Vectors
Demonstrates using Chilkat in Visual Basic 6.0 to computer HMAC MD5 message authentication codes to match the test vectors given by RFC 2202.
' This example assumes the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.
Dim crypt As New ChilkatCrypt2
' The output will be Hex, so set the EncodingMode:
crypt.EncodingMode = "hex"
' Set the hash algorithm:
' Choices are: md5, sha-1, sha256, sha384, sha512, md2, haval
crypt.HashAlgorithm = "md5"
Dim mac As String
' Set the HMAC key:
crypt.SetHmacKeyEncoded "0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b","hex"
mac = crypt.HmacStringENC("Hi There")
Debug.Print mac
crypt.SetHmacKeyEncoded "Jefe","ansi"
mac = crypt.HmacStringENC("what do ya want for nothing?")
Debug.Print mac
