在Go语言中，你可以使用crypto/rsa包来生成SSH密钥对。以下是一个简单的示例代码：
package mainimport ("crypto/rand""crypto/rsa""crypto/x509""encoding/pem""os")func generateSSHKeyPair(bitSize int) error {privateKey, err := rsa.GenerateKey(rand.Reader, bitSize)if err != nil {return err}privateKeyPEM := &pem.Block{Type: "RSA PRIVATE KEY",Bytes: x509.MarshalPKCS1PrivateKey(privateKey),}privKeyFile, err := os.Create("id_rsa")if err != nil {return err}defer privKeyFile.Close()err = pem.Encode(privKeyFile, privateKeyPEM)if err != nil {return err}publicKey := privateKey.Public()publicKeyPEM, _ := x509.MarshalPKIXPublicKey(publicKey)pubKeyFile, err := os.Create("id_rsa.pub")if err != nil {return err}defer pubKeyFile.Close()pubkeyBlock := &pem.Block{Type: "PUBLIC KEY",Bytes: publicKeyPEM,}err = pem.Encode(pubKeyFile, pubkeyBlock)if err != nil {return err}return nil}func main() {bitSize := 4096 // RSA密钥长度err := generateSSHKeyPair(bitSize)if err != nil {panic(err)}}
这段代码将生成一个4096位的RSA密钥对，并分别保存为id_rsa（私钥）和id_rsa.pub（公钥）文件。你可以根据自己的需求调整密钥长度和文件名。
