Question

我想使用javascript检测并验证公钥的格式你的任何图书馆都可以帮助我吗？基本上我希望用户将他的密钥粘贴到textarea然后我想解析它以验证这实际上是rsa \ ssh \ etc。键，获取密钥名称（描述），位大小和任何其他相关信息。谢谢。

你应该可以用正则表达式来做。这个匹配openssl输出的格式。

var re = new RegExp("^-----BEGIN CERTIFICATE-----\r?\n[A-Za-z0-9+\/=]{64}\r?\n[A-Za-z0-9+\/=]{64}\r?\n[A-Za-z0-9+\/=]{64}\r?\n[A-Za-z0-9+\/=]{64}\r?\n[A-Za-z0-9+\/=]{64}\r?\n[A-Za-z0-9+\/=]{64}\r?\n[A-Za-z0-9+\/=]{64}\r?\n[A-Za-z0-9+\/=]{64}\r?\n[A-Za-z0-9+\/=]{64}\r?\n[A-Za-z0-9+\/=]{64}\r?\n[A-Za-z0-9+\/=]{64}\r?\n[A-Za-z0-9+\/=]{64}\r?\n[A-Za-z0-9+\/=]{38}==\r?\n-----END CERTIFICATE-----\r?\n?$");

re.test("-----BEGIN CERTIFICATE-----\n"+
"MIICWDCCAcGgAwIBAgIJAPoiU8TwxKfZMA0GCSqGSIb3DQEBCwUAMEUxCzAJBgNV\n"+

// outputs 'true'
