Comprehensive overview of Go cryptography developments in 2024-2025, covering the implementation of post-quantum key exchanges (ML-KEM-768) in TLS and SSH, native FIPS 140-3 compliance without cgo, security improvements including hedged ECDSA and enhanced testing methodologies, performance optimizations across crypto packages, and the expansion of the Geomys maintenance team. The work maintains Go's strong security track record with no critical vulnerabilities since 2019 while adding significant new capabilities.
