HMAC MD5 to Match RFC 2022 Test Vectors

See more Encryption Examples

Demonstrates using Chilkat in _LANGUAGE_ to computer HMAC MD5 message authentication codes to match the test vectors given by RFC 2202. Visual FoxPro

LOCAL loCrypt
LOCAL lcMac

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

loCrypt = CreateObject('Chilkat.Crypt2')

* The output will be Hex, so set the EncodingMode:
loCrypt.EncodingMode = "hex"

* Set the hash algorithm:
* Choices are: md5, sha-1, sha256, sha384, sha512, md2, haval
loCrypt.HashAlgorithm = "md5"
loCrypt.MacAlgorithm = "hmac"

* Set the HMAC key:
loCrypt.SetMacKeyEncoded("0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b","hex")
lcMac = loCrypt.MacStringENC("Hi There")
? lcMac

loCrypt.SetMacKeyEncoded("Jefe","ansi")
lcMac = loCrypt.MacStringENC("what do ya want for nothing?")
? lcMac
