- qz-tray sha-256 not defined
I am trying to print the simple data text using Angular and Qz-Tray. But everytime I try to Print the error is displayed:
qz-tray.js:35 ReferenceError: Sha256 is not definedat Object.hash (qz-tray.js:408)at WebSocket._qz.websocket.connection.sendData (qz-tray.js:184)at qz-tray.js:280at j (rsvp.min.js:1)at new t (rsvp.min.js:1)at Object.promise (qz-tray.js:395)at Object.dataPromise (qz-tray.js:272)at Object.print (qz-tray.js:805)at PrinterService.push../src/app/shared/services/print.service.ts.PrinterService.printData (print.service.ts:46)at FoddListComponent.push../src/app/layout/foodlist/foddlist.component.ts.FoddListComponent.createPdf (foddlist.component.ts:122)I have included all the 3 .js files in index.html
Here is my index.html:

I'm having trouble understanding the principle/method, on how to "manually" calculate a binary file's hash (sha256) which consist of certain bytes.
To put into an example:
I have this binary file consisting of these bytes.
2C F2 BA A3 0E 26 5A 3B 2A 1F 01 4A 01 66 60 02How can I use my knowledge of binary files, bits, bytes, and hex to calculate the file's hash using these sites?

- Code signing with both sha1 and sha256 simultaneously?
Due to Windows changing their security policies, we are planning to begin code-signing driver files with the SHA-256 algorithm instead of SHA-1. However, we still want to be able to support older OS's that still require SHA-1 signing.
Using Microsoft's
signtool.exewe are able to code sign files successfully with both SHA-1 and SHA-256 digest algorithms using the /fd flag. However, if possible, we would like to sign the file with both algorithms simultaneously. Is this even possible? We would like to avoid having multiple sets of drivers that are signed with different algorithms and determining which set to install based on OS -- which would be our alternative approach.If anyone has had experience with accomplishing this please explain what approach you took. If this isn't possible, an explanation of why it's impossible would be appreciated.
- 'BadEncodingError' during Basic256sha256 encrypting in open62541
I was trying to connect a Server(both made by myself and downloaded from open62541 GitHub link ->server_basic256sha256.c) and a client (Prosys or UA_Expert).
The issue is that when I try to connect my client either goes into an infinite loop or, using a different client, send me back an error:BadEncodingError.
I supposed that is a library bug, because I've only copied Git code and I pasted it in mine. So as a double-check I downloaded the test source, as mentioned above.
I hope that someone can help me.
- Computing a test hash with python pbkdf2_hmac-sha256 + salt not the same vaules
For a encryption class i'm in we were tasked to make a program to check a password if the computer knows the following defined information. The teacher gave us a working set of fixed information.
I am trying to write a python code to verfiery a given set of user data based upon the known and fixed...
digest method: HMAC-SHA256
rounds: 100000
salt:"e65814e4382759f85550029e723dc7e7"

to output the derived: "5f37a3bd08ac1c7d163294a3cb192ed1407b62bbc6a6259fee55f6e53f754273"
This is my code to generate the derived to check the against the above derived...
key = hashlib.pbkdf2_hmac('sha256', b'governor washout beak', b'e65814e4382759f85550029e723dc7e7', 100000, dklen=32)print(binascii.hexlify(key))however I get "0ce7d2e654c0ba80e67348c9610ca1851312458166ee8c9e6d46666832a21b11"instead. I don't understand what is missing.
