Hi everyone,
I am looking for similar function on AC for Crypto library.
So, this piece of code should be adapted/translated to run on AC Classic:
...
const crypto = require('crypto');
sig = crypto.createHmac('sha1', appsecret).update(text).digest('bin');
...
I have found this AC function below but not sure is that good replacement.
Any suggestion?
Regards,
Milan
Hi,
You may use hmac as follow (hmacStr is deprecated):
var appsecret = "SECRET"
var text = "hello"
//var sig = hmacStr(text, appsecret, 'SHA1'); // @2371202
var mbKey = new MemoryBuffer(); // init memory buffer for the key
mbKey.fromString(appsecret, "utf-8"); // convert from string
var mbSignature = new MemoryBuffer(); // init memory buffer for the signature
mbSignature.fromString(text, "utf-8"); // convert from string
var sig = mbSignature.hmac(mbKey, 'SHA1'); // compute SHA-1 HMAC with key
logInfo('text:', text); // "hello"
logInfo('sig:', sig); // rAqO5eBQ+Z8pPOhAPsaztYNsKxQ=
However, it's not the digest in hexadecimal format as in nodeJS:
To do get the hex hmac, you have to use an external library, like jshashes:
loadLibrary('vendor:jshashes_1.0.8');
var appsecret = "SECRET";
var text = "hello";
var SHA1 = new Hashes.SHA1;
logInfo('SHA1: ' + SHA1.hex_hmac(appsecret, text)); // "SHA1: ac0a8ee5e050f99f293ce8403ec6b3b5836c2b14"Follow this link to import a js library in adobe campaign.
