什么是 DigiCert S/MIME Class 1 证书?

Digicert S/MIME Class 1是确保电子邮件通信安全的简单、经济和出色的解决方案。 该 SSL 证书使用 S/MIME 协议对电子邮件信息进行数字签名和加密。

DigiCert S/MIME Class 1 证书的优势

  • 电子邮件加密。 DigiCert S/MIME Class 1 对您的电子邮件进行数字签名,并在您和收件人之间实现端到端加密。 通过使用公钥/私钥对,您的私钥会一直留在您身边,用于签署发出的电子邮件和解密用您的公钥加密的收到的电子邮件。 您的公开密钥用于验证您的签名和加密发送给您的电子邮件。 人类无法破解 256 位加密和 2048 位签名密钥。
  • 符合 FDA ESG 标准。 如果您与 FDA(美国食品和药物管理局)有业务往来,则必须对电子邮件进行加密。 ESG(电子提交网关)在将您的电子邮件发送到 FDA 相关办公室之前会核实发件人的身份。 该电子邮件证书可确保与 FDA 的通信顺畅、安全。
  • 域名控制。 该电子邮件证书的获取既快捷又简单。 您只需证明您是要加密域名的所有者即可。 证书信息栏将显示您的电子邮件地址。
  • 与几乎所有平台兼容。 该产品几乎适用于所有服务器、电子邮件客户端和浏览器。 您可以将其安装在 Windows、Linux、Mac 和许多其他平台上。 它还支持主要的电子邮件服务器,如 Netscape Communicator、Microsoft Outlook、Microsoft Exchange 和 Mozilla Thunderbird。
  • 保护客户、合作伙伴和您的品牌。 对于各种规模的企业来说,电子邮件仍然是最有价值的工具。 不幸的是,它也是黑客最容易攻击的目标。 每天都有数以百万计的账户遭到入侵,因此现在比以往任何时候都更有必要保护您的企业通信。 DigiCert 负责保护您的电子邮件安全,防止数据泄露和曝光,让您和您的客户满意。

Great selection of certificates with a clear definition of properties for each certificate makes it easy to choose the right one.

Easier and cheaper than going directly and ordering via the vendor, thank you for the information and the simple shopping experience.

Excellent customer service when I ordered the wrong cert! The support team then helped me get the correct cert and refunded me on the incorrect cert I bought! Very fast and a happy customer.

One of the most reliable SSL brands. If you need to secure subdomains and can afford it, don’t think twice. Get it.

The price seems fair for an EV certificate, especially the two-year deal. Unlike my previous provider, which I won’t advertise here, at SSL Dragon, the buying steps are easier and better explained.

Always a pleasure doing business with SSL Dragon. Thawte certificates consistently deliver the highest encryption and customer trust.

Was assigned to secure several NGO sites. Picked this certificate because of a higher warranty and reasonable price. It’s always a pleasure to work with SSL Dragon.

This is the third SSL Certificate I buy from SSL Dragon, and the first one from GeoTrust. All I can say is the certs work as described in the specs, and the support is very friendly.

The SSL wizard recommended this certificate for our e-stores. We’re already on the third renewal, and during all these years, didn’t have a single issue with it.
