The Go Cryptography State of the Union
summary
Go 1.24 ships a ML-KEM + X25519 hybrid as the default key exchange in crypto/tls (also in SSH 0.38) so connections get post‑quantum protection without extra configuration. A FIPS 140-3 native Go module and optional GOFIPS140 frozen artifact cover algorithm testing across FreeBSD, macOS, Windows and ARM platforms. crypto/rsa avoids math/big for faster keygen, the library rejects RSA keys <1024 bits, AES-CTR is 2–9× faster, crypto/rand uses the Linux VDSO and never fails; Trail of Bits finds no issues in the Go primitives.
