如何在golang中生成x5t标头值

import (
    "crypto/sha1"
    "encoding/base64"
    "encoding/hex"
    "fmt"
)

func generateX5THeaderValue(certData []byte) (string, error) {
    // 计算证书的SHA-1哈希值
    hash := sha1.New()
    _, err := hash.Write(certData)
    if err != nil {
        return "", err
    }
    sha1Hash := hash.Sum(nil)

    // 将SHA-1哈希值转换为Base64编码
    base64Hash := base64.URLEncoding.EncodeToString(sha1Hash)

    // 将Base64编码转换为十六进制字符串
    hexHash, err := hex.DecodeString(base64Hash)
    if err != nil {
        return "", err
    }
    hexHashStr := hex.EncodeToString(hexHash)

    return hexHashStr, nil
}

func main() {
    // 读取证书数据
    certData := []byte("your_certificate_data")

    // 生成x5t标头值
    x5tHeaderValue, err := generateX5THeaderValue(certData)
    if err != nil {
        fmt.Println("Error:", err)
        return
    }

    fmt.Println("x5t标头值:", x5tHeaderValue)
}
