This update enhances security by utilizing the Module-Lattice-Based Key-Encapsulation Mechanism (ML-KEM) and enables the use of several strong algorithms such as Curve448, Curve25519, and other NIST-certified elliptic curve algorithms including RSA-4096 and RSA-3072.<\/p>\n<p>According to the IPFire developers, this addition is crucial as &quot;this algorithm is believed to be secure against adversaries who possess a quantum computer&quot;. The update is automatically enabled for all new tunnels, ensuring robust encryption standards are maintained.<\/p>\n<p>In addition to enhancing cryptography, IPFire 2.29 Core Update 193 updates the default cipher configurations for new tunnels, defaulting to AES-256 in GCM or CBC mode, or ChaCha20-Poly1305. The developers have removed AES-128 from the default list of ciphers due to its weaker security profile, emphasizing the improved performance of AES-256, which is now standard practice.<\/p>\n<p>The release also includes an updated toolchain with GNU C Library 2.41 and GNU Binutils 2.44, support for DNS-over-TLS among other new default services, and various bug fixes including a critical issue with IPsec host certificate renewal.<\/p>\n<p>You can download the latest update from the <a target=\"_blank\" rel=\"nofollow\" href=\"https:\/\/www.ipfire.org\/blog\/ipfire-2-29-core-update-193-released\">IPFire website<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>IPFire 2.29 Core Update 193 has officially launched, introducing post-quantum cryptography support for IPsec tunnels.
