HMAC with SHA256

See more Encryption Examples

Demonstrates how to compute a HMAC SHA256 keyed-hash message authentication code. Xbase++

LOCAL oCrypt
LOCAL cMac

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

oCrypt := CreateObject("Chilkat.Crypt2")

//  The output will be Hex, so set the EncodingMode:
oCrypt:EncodingMode := "hex"

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

//  Set the HMAC key:
oCrypt:SetMacKeyEncoded("The_API_Secret", "ascii")
cMac := oCrypt:MacStringENC("The quick brown fox jumps over the lazy dog")
? cMac
