我想使用 Windows 證書商店的證書包，誰(shuí)能告訴我我在這里做錯(cuò)了什么？我的代碼：package mainimport ( "fmt" "runtime" "github.com/google/certtostore")type certmgr struct { certToStore certtostore.CertStorage}func main() { if runtime.GOOS == "windows" { var cert certmgr certInStore, err := cert.certToStore.Cert() if err != nil { fmt.Println("message", "Error in getting system store certificate ...") } fmt.Println("Windows System Store Certificate", *certInStore) }}我得到的錯(cuò)誤：panic: runtime error: invalid memory address or nil pointer dereference[signal 0xc0000005 code=0x0 addr=0x0 pc=0xbe2dda]goroutine 1 [running]:main.main() C:/Users/prajwal.bhagat/go/src/phoenix/mainsvc/cmd/main/test.go:17 +0x1aexit status 2

您可以使用類似 的庫(kù)google/certtostore，它是一個(gè)多平臺(tái)包，允許您在 Linux 上使用 x509 證書，在 Windows 上使用證書存儲(chǔ)。
它不直接獲取證書包，而是使用WindowscertGetCertificateChain調(diào)用，該調(diào)用從最終證書開(kāi)始構(gòu)建證書鏈上下文，并在可能的情況下返回到受信任的根 CA。
它由 所使用CertWithContext()，它使用創(chuàng)建時(shí)提供的頒發(fā)者值執(zhí)行證書查找WinCertStore。
它返回證書及其 Windows 上下文，可用于執(zhí)行其他操作，例如使用 查找私鑰CertKey()。

你需要初始化var cert certmgr
更一般地說(shuō)，您需要先獲取商店，如本例所示：
fmt.Println("open cert store")
// Open the local cert store. Provider generally shouldn't matter, so use Software which is ubiquitous. See comments in getHostKey.
store, err := certtostore.OpenWinCertStore(certtostore.ProviderMSSoftware, "", []string{"localhost"}, nil, false)
if err != nil {
fmt.Errorf("OpenWinCertStore: %v", err)
return
}
fmt.Println("get cert from cert store")
// Obtain the first cert matching all of container/issuers/intermediates in the store.
// This function is indifferent to the provider the store was opened with, as the store lists certs
// from all providers.
crt, context, err := store.CertWithContext()
if err != nil {
fmt.Println("failed to get cert from cert store. ", err)
return
}
if crt == nil {
fmt.Println("no cert")
return
}
fmt.Println("get key from cert")
// Obtain the private key from the cert. This *should* work regardless of provider because
// the key is directly linked to the certificate.
key, err := store.CertKey(context)
if err != nil {
fmt.Printf("private key not found in %s, %s", store.ProvName, err)
return
}
if key == nil {
fmt.Println("no key")
return
}
fmt.Printf("find cert '%s' with private key in container '%s', algo '%s'\n", crt.Subject, key.Container, key.AlgorithmGroup)
