NodeJS get SubjectPublicKeyInfo
问题
我尝试将这段Go代码转换为NodeJS。这段Go代码下载给定主机的TLS证书，并为主题公钥信息创建一个哈希值。
func Fingerprint(c *x509.Certificate) string {
digest := sha256.Sum256(c.RawSubjectPublicKeyInfo)
return base64.StdEncoding.EncodeToString(digest[:])
}
func fromServer(server string) error {
conn, err := tls.Dial("tcp", server, &tls.Config{
InsecureSkipVerify: true,
})
if err != nil {return err}
for _, cert := range conn.ConnectionState().PeerCertificates {
fmt.Println(Fingerprint(cert))
}
return nil
}
我写了以下代码：
function fingerprint(cert) {
const digest = crypto.createHash('sha256').update(cert).digest();
return Buffer.from(digest).toString('base64');
}
function fromServer(server) {
const socket = tls.connect({ host: server.split(':')[0], port: server.split(':')[1], rejectUnauthorized: false }, () => {
const cert = socket.getPeerCertificate();
// console.log(fingerprint(cert.??))
socket.end();
});
}
我的问题是，我找不到用于指纹的值。在Go代码中，我使用fmt.Println(hex.EncodeToString(c.RawSubjectPublicKeyInfo))记录了RawSubjectPublicKeyInfo的值，而在NodeJS中，我无法找到它的"独立"值或将原始证书转换的方法。
英文:
I try to convert this Go code into NodeJS. The Go code downloads the tls cert for a given host and creates a hash for the subject pulic key info.
func Fingerprint(c *x509.Certificate) string {
digest := sha256.Sum256(c.RawSubjectPublicKeyInfo)
return base64.StdEncoding.EncodeToString(digest[:])
}
func fromServer(server string) error {
conn, err := tls.Dial("tcp", server, &tls.Config{
InsecureSkipVerify: true,
})
if err != nil {return err}
for _, cert := range conn.ConnectionState().PeerCertificates {
fmt.Println(Fingerprint(cert))
}
return nil
}
I came up with this code
function fingerprint(cert) {
const digest = crypto.createHash('sha256').update(cert).digest();
return Buffer.from(digest).toString('base64');
}
function fromServer(server) {
const socket = tls.connect({ host: server.split(':')[0], port: server.split(':')[1], rejectUnauthorized: false }, () => {
const cert = socket.getPeerCertificate();
// console.log(fingerprint(cert.??))
socket.end();
});
}
My problem is that i cant find the value the is used for the fingerprint. In Go i logged theRawSubjectPublicKeyInfo with fmt.Println(hex.EncodeToString(c.RawSubjectPublicKeyInfo)) and the value is part of the NodeJS cert.raw.toString('hex') but i didn't found it "standalone" or a way to convert the raw cert.

这个文档没有具体说明，但是.pubkey是一个包含（DER编码的）SPKI的Buffer，这正是你想要的。至少从dockerhub的node:10-alpine版本开始有这个属性；8或更低版本似乎没有。
英文:
The doc isn't specific, but .pubkey is a Buffer containing (DER-encoded) SPKI, which is what you want. At least since the version in dockerhub's node:10-alpine; 8 or lower doesn't seem to have it.
