At the same time, VeraCrypt provides a compatibility mode with […]

A vulnerability in Ghostscript allows for code execution when opening a PostScript document.

uWSGI Recipes: Document Conversion Using LibreOffice

Posted on

To prepare for document transformation, we will need LibreOffice, uwsgi-python, pylokit, and webob. A ready-made image can also be used, but that is just for starting the uWSGI server, while we'll use nginx to connect to the uWSGI server. The simplest uWSGI application in Python consists of an application function with two arguments: environ and start_response import os # import import pylokit # necessary imports import tempfile […]

China has begun blocking HTTPS connections established with TLS 1.3 and ESNI.

Posted on

China has implemented a block on all HTTPS connections that use the TLS 1.3 protocol and the TLS extension ESNI (Encrypted Server Name Indication), which provides encryption for data about the requested host.
