Explore the latest developments in Go's cryptography ecosystem through this comprehensive conference talk from GopherCon 2025. Learn about the significant updates introduced in Go 1.24, including the addition of a new maintainer, implementation of post-quantum cryptography, native FIPS 140 support, and a complete rewrite of crypto/rsa. Discover improvements in systematic testing methodologies, the integration of x/crypto packages into the standard library, and performance enhancements for AES-CTR encryption. Examine the more testable ECDSA implementation and understand the rationale behind the rare backwards compatibility break that now rejects RSA keys too small to provide adequate security. Gain insights into additional developments such as external security audits, Encrypted Client Hello implementation, and the new crypto/rand vDSO system that ensures reliable random number generation. Understand the maintenance techniques and strategies used to keep Go's cryptography libraries secure, efficient, and up-to-date with current security standards and best practices.
