我正在嘗試使用 Go 的RSA包加密密碼。這是我到目前為止所擁有的：package mainimport (    "fmt"    "time"    "net/http"    "strconv"    "io/ioutil"    "encoding/json"    "errors"    "crypto/rsa"    "crypto/rand"    //"math/big")func main() {    if err := Login("username", "password"); err != nil {        fmt.Println(err)    }}func Login(username, password string) error {    doNotCache := strconv.FormatInt(time.Now().UnixNano() / int64(time.Millisecond), 10)    // Get RSA Key    resp, err := http.PostForm("https://steamcommunity.com/login/getrsakey/", map[string][]string{        "donotcache": {doNotCache},        "username": {username},    })    if err != nil {        return err    }    content, err := ioutil.ReadAll(resp.Body)    if err != nil {        return err    }    var decoded map[string]interface{}    err = json.Unmarshal(content, &decoded)    if err != nil {        return err    }    if decoded["success"] != true {        return errors.New("Failed to retrieve RSA key.")    }    // Set encryption variables    var privateKey *rsa.PrivateKey    var publicKey *rsa.PublicKey    var plain_text, encrypted []byte    plain_text = []byte(password)    // Generate Private Key    if privateKey, err = rsa.GenerateKey(rand.Reader, 1024); err != nil {        return err    }    privateKey.Precompute()    if err = privateKey.Validate(); err != nil {        return err    }    publicKey.N = decoded["publickey_mod"].(string) // <- This is not right, I need to create a modulus from the publickey_mod string and it needs to be of type big.Int    publicKey.E = decoded["publickey_exp"].(int)    encrypted, err = rsa.EncryptPKCS1v15(rand.Reader, publicKey, plain_text)    if err != nil {        return err    }    fmt.Printf("PKCS1 Encrypted [%s] to \n[%x]\n", string(plain_text), encrypted)    return nil}我無法從給定的字符串將 publicKey.N 值設(shè)置為 big.Int。和變量decoded["publickey_mod"]看起來像010001我正在嘗試為https://steamcommunity.com/加密此密碼。
