In the issue report you mention "I use Go to parse this CRL file, Go interprets". Can you please provide a snippet of code for that? In particular, that code will help determine if the problem is in the crypto/x509 package, or how it's being used.

Please see https://go.dev/wiki/Questions for asking questions about Go.

package main

import (
    "crypto/x509"
    "encoding/asn1"
    "fmt"
    "io/ioutil"
    "os"
    "math/big"
)

func main() {

    derBytes, err := ioutil.ReadFile("crl_file_.der")
    if err != nil {
        fmt.Println(err)
        os.Exit(1)
    }

    crl, err := x509.ParseRevocationList(derBytes)
    if err != nil {
        fmt.Println(err)
        os.Exit(1)
    }
    fmt.Printf("%s\n",crl.Issuer)
    fmt.Printf("%s\n",crl.ThisUpdate)
    fmt.Printf("%s\n", crl.NextUpdate)
    fmt.Printf("%d\n", len(crl.RevokedCertificates))
}

Thanks. The value of crl.Issuer.Organization contains only one backslash character:

Organization:[]string{`VeriSign\`}

And the String method prints that one backslash in escaped format. Here's a smaller repro:

package main

import (
	"crypto/x509/pkix"
	"fmt"
)

func main() {
	name := pkix.Name{Organization: []string{`abc\`}}
	fmt.Println(name)

	// Output: O=abc\\
}

Hello, developer. Do you mean that it is normal for the Name parsed by Go to appear in its raw string format?

see https://www.rfc-editor.org/rfc/rfc2253#section-2.4

I believe this this working as intended.
