今日不肯埋头，明日何以抬头！每日一句努力自己的话哈哈~哈喽，今天我将给大家带来一篇《将自签名证书作为受信任的根证书添加到 Apple 钥匙串》，主要内容是讲解等等，感兴趣的朋友可以收藏或者有更好的建议在评论提出，我都会认真看的！大家一起进步，一起学习！
问题内容我正在尝试使用以下 go 脚本将自签名证书添加到 macos 设备上的系统钥匙串：
package main
import (
"crypto/rand"
"crypto/rsa"
"crypto/x509"
"crypto/x509/pkix"
"encoding/pem"
"math/big"
"os"
"os/exec"
"time"
"github.com/sirupsen/logrus"
)
func main() {
keyfilename := "key.pem"
certfilename := "cert.pem"
// generate a self-signed certificate (adapted from https://golang.org/class="lazy" data-src/crypto/tls/generate_cert.go)
key, err := rsa.generatekey(rand.reader, 4096)
if err != nil {
logrus.witherror(err).fatal("generate key")
}
keyfile, err := os.create(keyfilename)
if err != nil {
logrus.witherror(err).fatal("create key file")
}
if err = pem.encode(keyfile, &pem.block{
type: "rsa private key",
bytes: x509.marshalpkcs1privatekey(key),
}); err != nil {
logrus.witherror(err).fatal("marshal private key")
}
keyfile.close()
template := x509.certificate{
serialnumber: big.newint(42),
subject: pkix.name{
country: []string{"us"},
organization: []string{"awesomeness, inc."},
organizationalunit: []string{"awesomeness dept."},
commonname: "awesomeness, inc.",
},
notbefore: time.now(),
notafter: time.now().adddate(10, 0, 0),
keyusage: x509.keyusagekeyencipherment | x509.keyusagedigitalsignature | x509.keyusagecertsign,
extkeyusage: []x509.extkeyusage{x509.extkeyusageserverauth},
isca: true,
basicconstraintsvalid: true,
}
derbytes, err := x509.createcertificate(rand.reader, &template, &template, &key.publickey, key)
if err != nil {
logrus.witherror(err).fatal("failed to create certificate")
}
certfile, err := os.create(certfilename)
if err != nil {
logrus.witherror(err).fatal("create cert file")
}
if err = pem.encode(certfile, &pem.block{
type: "certificate",
bytes: derbytes,
}); err != nil {
logrus.witherror(err).fatal("encode certificate")
}
certfile.close()
args := []string{"add-trusted-cert", "-k", "/library/keychains/system.keychain", "-r", "trustasroot", certfilename}
output, err := exec.command("/usr/bin/security", args...).combinedoutput()
if err != nil {
logrus.fatalf("add-trusted-cert: %v - %s", err, output)
}
}但是，当我使用 sudo 运行此脚本时，我得到一个相当不具体的“传递给函数的一个或多个参数无效”。错误：
> sudo go run add_to_keychain_trusted.go
Password:
FATA[0002] add-trusted-cert: exit status 1 - SecTrustSettingsSetTrustSettings: One or more parameters passed to a function were not valid.
exit status 1我注意到的一件事是，如果我使用 -r trustroot 选项而不是 -r trustasroot，则该命令有效。也许不再支持 -r trustasroot 选项（尽管它记录在 man security 页面中）？
解决方案
在 https://www.jamf.com/jamf-nation/discussions/13812/problems-importing-cert-via-terminal 之后，我通过编写包含证书的配置文件并使用 profiles 命令行工具安装该配置文件来解决此问题，而不是直接使用 security 工具。这是改编后的脚本：
package main

// NewProfile creates a new configuration profile
func NewProfile() *Profile {
payloadUUID := uuid.NewV4()
return &Profile{

}
// NewPayload creates a new payload
func NewPayload(payloadType string) *Payload {

func NewCertificateProfile(certPEM []byte) *Profile {

profile.PayloadDescription = "Awesome Payload"
profile.PayloadDisplayName = "Awesome Certificate"
profile.PayloadIdentifier = "com.awesomeness.certificate"
profile.PayloadScope = "System"
profile.PayloadOrganization = "Awesomeness, Inc."
payload := NewPayload("com.apple.security.pem")
payload.PayloadDescription = "Awesome Certificate"
payload.PayloadDisplayName = "Awesome Certificate"
payload.PayloadOrganization = "Awesomeness, Inc."
payload.PayloadIdentifier = profile.PayloadIdentifier + "." + payload.PayloadUUID
certificatePayload := CertificatePayload{

PayloadContent: certPEM,

profile.PayloadContent = []interface{}{certificatePayload}
return profile
}
func generateSelfSignedCertificate(keyFileName, certFileName string) {
// Generate a self-signed certificate (adapted from https://golang.org/class="lazy" data-src/crypto/tls/generate_cert.go)

derBytes, err := x509.CreateCertificate(rand.Reader, &template, &template, &key.PublicKey, key)
if err != nil {
logrus.WithError(err).Fatal("failed to create certificate")
}
certFile, err := os.Create(certFileName)
if err != nil {

}
if err = pem.Encode(certFile, &pem.Block{

logrus.WithError(err).Fatal("encode certificate")
}
certFile.Close()
}
func main() {
keyFileName := "key.pem"
certFileName := "cert.pem"
profileFileName := "certificate.mobileconfig"
generateSelfSignedCertificate(keyFileName, certFileName)
certPEM, err := ioutil.ReadFile(certFileName)
if err != nil {
logrus.WithError(err).Fatal("read certificate file")
}
certificateProfile := NewCertificateProfile(certPEM)
mobileconfig, err := plist.MarshalIndent(certificateProfile, plist.XMLFormat, "\t")
if err != nil {
logrus.WithError(err).Fatal("marshal plist")
}
if err := ioutil.WriteFile(profileFileName, mobileconfig, 0755); err != nil {
logrus.WithError(err).Fatal("write mobileconfig to file")

output, err := exec.Command("/usr/bin/profiles", args...).CombinedOutput()
if err != nil {
logrus.Fatalf("%s: %v - %s", "/usr/bin/profiles"+strings.Join(args, " "), err, output)
}
}使用 sudo -e go run add_certificate.go 运行此命令后，通用名为 awesomeness 4, inc. 的证书在我的钥匙串中显示为受信任的证书：
