Cryptography
The ring cryptography package maintenance status underwent changes, initially being declared unmaintained but later receiving security-focused maintenance from the rustls team. The advisory highlights potential security implications for users of the ring crate, with the rustls team committed to addressing critical security issues.
A security engineer specializing in cryptography announces a detailed review of Signal's cryptography, emphasizing the importance of proper security audits and transparency in messaging apps. The review aims to make applied cryptography understanding accessible to everyone, while addressing common misconceptions about encrypted messaging platforms.
Go 1.24 introduces significant performance improvements with a new Swiss Tables-based map implementation and enhanced memory allocation efficiency, reducing CPU overheads by 2-3%. The release adds support for ML-KEM post-quantum cryptography, FIPS 140-3 compliance mechanisms, and new testing tools for concurrent code.
A comprehensive explanation of the XOR operator, from its basic logic operations to advanced mathematical applications in cryptography, game theory, and finite fields, illustrated with practical examples in computing and theoretical concepts.
Kagi Search introduces Privacy Pass authentication, allowing users to access search services anonymously while verifying their right to access, alongside a new Tor onion service for enhanced privacy. The feature enables users to perform searches without linking them to their accounts, making tracking technically impossible rather than just policy-based.
A detailed exploration of why cryptography relies on average-case hard problems rather than NP-complete problems, explaining how cryptographic security requires randomly selected problem instances to be consistently difficult. The discussion clarifies the distinction between worst-case hardness in complexity theory and the practical requirements for cryptographic security, using RSA as a primary example.
Alan Turing's secret 'Delilah' project from 1943-1945 resulted in a groundbreaking portable voice-encryption system, demonstrating his largely unknown expertise in electrical engineering. Recently discovered documents, known as the 'Bayley papers,' reveal Turing's detailed work on this innovative system that could encrypt and decrypt speech using pseudorandom number generation and advanced circuit design. The project showcased Turing's transition from theoretical mathematics to practical engineering, laying groundwork for his later contributions to computer design.
