RE: Barcode

Even when we were using bar code fonts, we would always purchase them to ensure the quality of the image. These need to be precise, especially if your using compact, high density codes. Free fonts are really not free... Steve -Original Message- From: 4D_Tech <4d_tech-boun...@lists.4d

Re: Barcode

it seems like on some versions of 4D (for Mac), an invisible character is appended at the end for alignment. that would screw up the barcode data. 2020/03/21 2:01、Lee Hinde via 4D_Tech <4d_tech@lists.4d.com>のメール: But we ended up using hmBarcode because the free fonts

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 bin

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 \""+$Key+"\""

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

RE: Barcode

As I've said previously, we also switched away from fonts (to hmBarcode) for varying reasons: 1. The various Windows OS updates have caused problems due to the changes on how they index fonts internally. 2. Bar code fonts are not part of the normal Windows font list, so you need to have a way

Looks like you pad the key, append the msg, then hash. Then pad the key again, append the previous hash, and hash again. https://stackoverflow.com/questions/11415055/how-to-use-hmac-sha256 From: Two Way Communications Date: Friday, March 20, 2020 at 9:37 AM To: Spencer Hinsdale Cc: 4D iNug T

Hi Spencer, I have been looking at it, but it does not do what I want to do. I need to construct a JSON Web Token (JWT) For that, I need to encrypt a string with a secret key, to obtain the encrypted token. As far as I can see there is no parameter in ‘Generate Digest' to do so. I tried to use
