kandi X-RAY | xcd Summary

xcd is a C library. xcd has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

This program provides a colorized version of xxd(1), assigning colors to byte values found in the input, thus making it easier to see patterns of repeated values. The source code also provides a very simple example of using the tinfo library to inject control codes into standard output, without having to conform to curses's presentation-based API. To build, simply run "make". The resulting executable runs standalone. If you wish to install the program to a shared location, just use cp(1).

why is this signature different from the original after creating a qr code and scanning it with pyzbar?

Asked 2022-Mar-29 at 06:25

I'm generating a digital signature(using https://pypi.org/project/rsa/) and saving it on a qrcode(using https://pypi.org/project/qrcode/) so I can distribute them on paper and scan them later. However, the byte sequence scanned is different from the one i originally created, why the verification fails.

The following code

ANSWER

Answered 2022-Mar-29 at 06:25

I would highly recommend that you encode whatever you want to sign in base64 before signing. This is a standard approach for digital signatures, ensuring consistency of the signed data.
The output of the pyzbar.decode function is an array of "Decoded" objects, of which you're not retrieving the correct element.

Below the corrected code:

Django Python: How do I decrypt an AES-CTR mode encrypted file in the Python shell?

Asked 2022-Mar-22 at 20:33

I'm using https://github.com/eblocha/django-encrypted-files to encrypt files uploaded to a server through a simple contact form app in Django. django-encrypted-files uses AES in CTR mode to encrypt an uploaded file via an upload handler while streaming the file to the server.

What I'm trying to do is manually decrypt the encrypted file by downloading the file via FTP and decrypting it locally in the Python shell. I do not want or need to stream decrypt the file from the server or modify django-encrypted-files; I only want to manually download and then decrypt files locally in the Python shell.

The problem is I can't get local Python decryption to work. The docs at Cryptography show an example of encryption and decryption using a sample text input in the Python shell. But there are no examples of encrypting/decrypting a file.

The code below what I'm trying to use in the Python shell. The original file uploaded via Django is uploaded_file.txt. The encrypted file downloaded from the server is encrypted.txt; the file to save the decrypted text to is decrypted.txt.

But when I try the code below, the decrypted.txt is empty. Is this an issue with writing the file? Or an issue with the iv?

What is a working example of decrypting a AES-CTR mode file in the local Python shell?

During encryption, IV and ciphertext are concatenated: IV || ciphertext. During decryption, a random IV is used, which is wrong. Instead, the IV of the encryption must be applied. For this, IV and ciphertext have to be separated.
In addition, the update() and finalize() methods must be called, which perform the actual decryption.

The following code essentially matches your code, extended by the missing parts:

ANSWER

Answered 2022-Mar-16 at 12:41

You are misdiagnosing the problem - the error does not happen during the struct.pack call, but when you try to concatenate the result of that call to the payload variable.

The error message is telling you the problem. You initially define your payload as a string, but the result of the struct.pack call is a bytes object. You can't concatenate bytes to strings.

Probably, you want to define the original payload as a bytes object, like this:

QUESTION

Encode and Decode with Base64 and Pickle

Asked 2022-Mar-03 at 16:56

I need to pickle a dict, then Base64 encode this before transporting the data via an API call..

The receiver should decode the Base64 data and the pickle load it back in to a proper dict.

Issue is that it fails on the decoding of it, it doesn't seem to be the same binary data after Decode the Base64 data, hence the Pickle fails.

What am I missing?

Answered 2022-Mar-03 at 16:56

Call data.decode() or the equivalent str(data, encoding='utf-8') to convert the bytes to a valid base64-encoded string:

Elastic Beanstalk environment is failing suddenly. Why?

Asked 2022-Jan-27 at 17:18

I am at a complete loss and really freaking out, because this project of mine was close to being done. I will give out a bounty for the answer that helps me (when I can). I am desperate, please help.

I have an Elastic Beanstalk project that has been working fine for literally months. Today, I decide to enable and disable a port listener as seen in the photo below:

I enabled port 80 and then the website stopped working. So I was like "oh crap, I will change it back". But guess what? It is still broken. The code has not changed whatsoever, but the application is now broken and I am freaking out.

I have restarted the app servers, rebuilt the environment and nothing. I can't even access the environment site by clicking Go to environment. I just see a Bad Gateway message on screen. The health status of the environment when first deployed is OK and then quickly goes to Severe.

If my code has not changed, what is the deal here? How can I find out what is going on here? All I changed was that port, by enabling and then disabling again.

I have already come across this question: Question and I am already doing this. This environment variable is on my application.properties file like this: server.port=5000 and its been like this for months and HAS ALREADY been working. So this can't be the reason that it broke today. I even tried adding it directly to the environment variables in Elastic Beanstalk console and same result, still getting 502 Bad Gateway.

I also have a path for the health-check configured and this has not changed in months.

Here are the last 100 lines from my log file after health status goes to Severe:
