Node.js x509.checkIssued(otherCert) 方法

简介

在Node.js中，x509.checkIssued(otherCert)方法用于检查当前证书是否由其他证书签发。该方法是Node.js中内置的x509模块的一部分，用于操作和验证X.509数字证书。

语法

x509.checkIssued(otherCert)

参数

• otherCert：用于验证当前证书的其他证书，必须是x509.Certificate类型的对象。

返回值

• 如果当前证书由其他证书签发，则返回true，否则返回false。

示例

const x509 = require('x509');

const cert = x509.parseCert('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');

const isIssued = cert.checkIssued(otherCert);
console.log(isIssued);
// Output: true

以上示例中，我们用x509.parseCert方法分别解析了两个证书，并将其分别赋值给cert和otherCert变量。然后，我们调用cert对象的checkIssued()方法，将otherCert传递给它。最后，查看返回值并将其打印出来。结果为true，表示当前证书cert由otherCert证书签发。

结论

x509.checkIssued(otherCert)方法在Node.js中使用x509模块验证X.509数字证书时非常有用，可以帮助我们确定一个证书是否由其他证书签发。当我们需要架设安全认证系统、构建加密通信时，可以使用这个方法来进行必要的证书验证。
