(Visual Basic 6.0) HMAC SHA-1 to Match RFC 2022 Test Vectors
Demonstrates using Chilkat in Visual Basic 6.0 to computer HMAC SHA-1 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 = "sha-1"
Dim mac As String
' Set the HMAC key:
crypt.SetHmacKeyEncoded "0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b","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
