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

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Crypt2')
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"

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

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