文件签名证书的好处

文件签署证书是当今世界不可或缺的一部分。 公共和私营部门都在日常业务中对电子文档进行数字签名,并需要数字签名来增强安全性、实现无缝编辑和快速共享。 以下是文件签署的几个好处:

防弹加密和无与伦比的安全性

数字文档签名证书几乎无法伪造。 理论上,只有假想的量子计算机才能破解 2048 位密钥加密。

为您的钥匙提供额外保护

数字文件包括一个 iKeyUSB 令牌,用于存储你的私人密钥。 它还提供双因素身份验证,将数字签名安全性提升到一个新水平。

无可置疑的公信力

通过广泛的审查程序核实和确认发件人身份的电子文件具有法律约束力。 当您对 PDF 文档进行数字签名时,它们符合美国联邦 ESIGN 法案和各种国际法律的规定。

Adobe® Acrobat 文档完整性

Sectigo 文档签名证书允许组织使用数字签名对 Adobe Acrobat 文档进行加密。 认证由 Adobe 认证文档服务(CDS)或认证机构(Adobe Approved Trust List,AATL)成员颁发。

业务验证和提高信任度

业务验证为合作伙伴和客户提供了更高程度的信任和保证,即文件是由诚信经营的真实组织的代表签署的。

完全兼容浏览器

任何文档签名证书都与大多数浏览器和桌面平台完全兼容。 您可以将其用于微软产品和 Libre Office 等开源替代产品,还可以在移动设备上签署文档。

文件签名证书如何工作?

当有人修改数字文档时,接收者会收到通知。 数字签名支持时间戳,提供额外的安全性。

文件签名证书依靠数字签名来验证发件人和保护数据。 数字签名与手写签名类似,但与实体签名或电子签名不同,数字签名几乎无法伪造。

在对文档进行数字签名时,会启用超安全的 PKI(公钥基础设施)协议,该协议使用高级散列算法生成一对密钥。

私钥使你的数字签名独一无二,而公钥则对你的数字签名进行解密,允许文件接收者打开并查看文件。 他们还可以检查文档的作者证书,以确保文档的真实性。

像 Sectigo 这样的证书颁发机构负责监督整个文件签署过程。 该第三方实体提供的数字文档签名证书符合所有签发和安全合规准则。

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.
