Re: HMAC SHA256 in native 4D code

Hi Bruno, Thank you very much. This does in fact generate the correct JWT. I did check where the differences are, comparing to my code: Apparently, when using the php function ‘hash_hmac’, or when using Openssl through LEP, I get another signature than the one I get from your component. I am

Re: HMAC SHA256 in native 4D code

Hi Ruby, I sent you a component which does HMAC 256 and JWT object signing. It is all native. Lets us know if it works. Bruno LEGAY A Consulting ** 4D Internet Users Group (4D iNUG) Archive: http://lists.4d.com/archives.html

if a single PHP function does not produce results in a format you can use, you might have to encapsulate your call in a script file. 2020/03/21 4:48、Two Way Communications via 4D_Tech <4d_tech@lists.4d.com>のメール: With the ’True’ parameter, the php function returns

Here is a method we use on Windows: // SHAHMACEncode_Server 3/21/18 // C_TEXT($1;$2;$3;<>SHAHMAC) // 3/15/18 // $Value:=$1 // 3/15/18 $Key:=$2 // 3/15/18 $Client:=$3 // 3/15/18 // vCommand:="/bin/bash" // 3/21/18 // vInput:="echo -n \""+$Value+"\" | openssl sha1 -hmac

Re: HMAC SHA256 in native 4D code?

I did use PHP execute, then did a Base64 encode on it, and then cleaned ‘+’, ‘/‘ and ‘=‘. Still got an invalid signature. With the ’True’ parameter, the php function returns binary; often this is empty. With the parameter set to false, you get what they call ‘lowercase hexies’. No clue at all

Hi, I had to spend some time looking into this recently myself. You have two options: 1 - K. Miyako has a plugin - CommonCrypto. Easy to use. $signature:=HMACSHA256 ($keyData;$stringData;Crypto BASE64) 2 - Use PHP execute, but then encode the result (assuming you need to) php

Hi Bruno, I was looking in nabble to find a solution for generating HMAC-SHA256 keys. I have been trying to generate JSON web tokens, but they fail because of an invalid signature. I tried using : PHP Execute("";"hash_hmac";$HMACSHA256;"sha256";($base64UrlHeader+"."+$base64UrlPayload);$key),

Hi, Yes. HMAC-256 is quite simple (even more since sha256 is native). I can send you some code if you want. HTH Bruno ** 4D Internet Users Group (4D iNUG) Archive: http://lists.4d.com/archives.html Options:

RE: HMAC SHA256 in native 4D code?

Hi Bill, I have some older code in the ACME Client technote (http://kb.4d.com/assetid=77708) that perhaps could be repurposed. It doesn't do HMAC but it could get you started and maybe after you adapt the code it will work for your purposes. The code works natively on MacOS because MacOS
