Worth knowingecosystem
- What changed
- Security fixes to the crypto/elliptic package, plus bug fixes to the compiler and the go command.
- Production impact

- Try it
- Upgrade to go1.22.12 and run
go test ./...to ensure no regressions. - Source
- go.dev/doc/devel/release#go1.22.12
Understand it, then run it
Run it now
// This program demonstrates using the crypto/elliptic package to generate
// a P256 key pair and print the public point. It runs with Go 1.27.1
// and works with the security fix shipped in Go 1.23.6.
package main
import (
"crypto/elliptic"
"crypto/rand"
"fmt"
)
func main() {
// Choose the P256 curve.
curve := elliptic.P256()
// Generate a private/public key pair.
priv, x, y, err := elliptic.GenerateKey(curve, rand.Reader)
if err != nil {
panic(err)
}
// Display the private key (in hex) and the public point coordinates.
fmt.Printf("Private key: %x\n", priv)
fmt.Printf("Public key X: %x\n", x)
fmt.Printf("Public key Y: %x\n", y)
}
What it printed when we ran it on Go 1.27.1
Private key: c162f425a1badbccbe04e38b14b409af6a176f425d995395f43bcb150bc2249d Public key X: 11a1e8637c25e9b2cf3ae80b151e1a444363d35f9e0334b715899f4483ecb2ca Public key Y: 4186310a86cb438ce807b3e43e5e4c1802066e29259dc0325a5f4f3566011607
Run sends this program (for Solidity, the contract and its tests) to our own sandbox, where it is compiled and run once, with no network, and what it printed or the test report comes back here. Nothing is kept. Runs are counted per visitor for the day so everyone gets a turn; the details are on the legal page.
