On September 30 at 17:01 Moscow time, the root certificate of IdenTrust (DST Root CA X3) will expire, which was used for cross-signing the root certificate of the Let’s Encrypt certificate authority (ISRG Root X1), controlled by the community and providing free certificates to all who wish. The cross-signature provided trust in Let’s Encrypt certificates across a wide range of devices, operating systems, and browsers […]
After three and a half years of development, the first stable release of the GNU Wget2 project has been presented, which develops a completely reworked version of the program for automating recursive content downloads, GNU Wget. GNU Wget2 has been designed and rewritten from scratch, notably moving the core functionality of the web client into the libwget library, which can be independently used in applications. The utility is distributed under the GPLv3+ license, while the library is under […]
The release of OpenSSH 8.8 has been published, an open implementation of the client and server for working with SSH 2.0 and SFTP protocols. The release is notable for disabling the use of RSA key-based digital signatures with SHA-1 hashing ("ssh-rsa") by default. The discontinuation of support for "ssh-rsa" signatures is due to the increasing effectiveness of collision attacks with a predefined prefix (the cost of finding a collision is estimated at around $50,000). For […]
At the recent Linux Plumbers 2021 conference, Google discussed the progress of its initiative to transition the Android platform to use the standard Linux kernel instead of a custom version that includes Android-specific changes. The most significant update in development was the decision to adopt an "Upstream First" model after 2023, which involves developing all new kernel features needed for […]
The new release of the JavaScript engine elk 2.0.9 is available, aimed at use in resource-constrained systems such as microcontrollers, including ESP32 and Arduino Nano boards with 2 KB of RAM and 30 KB of Flash. The virtual machine requires only 100 bytes of memory and 20 KB of storage space to operate. The project code is written in C and is distributed under the […]
