签名证书

Ⅰ 签名证书与自签名证书的区别

签名证书：由权威颁发机构颁发给服务器或者个人用于证明自己身份的东西，默认客户端都是信任的。主要目的是用来加密和保证数据的完整性和不可抵赖性

自签名证书：由服务器自己颁发给自己，用于证明自己身份的东西，非权威颁发机构发布，默认客户端都是不信任的，主要目的是用来加密和保证数据的完整性和不可抵赖性,与签名证书相同.

详细具体解释见下面英文。
When you're building an ecommerce site one of the first things you'll need to set up is a security certificate so that your server data will be secure. When you set this up, you have the option of creating a self-signed cerficate or creating a certificate approved by a certificate authority.
Similarities Between Signed and Self-Signed Certificates
Whether you get your certificate signed by a certificate authority or sign it yourself, there is one thing that is exactly the same on both:
Both certificates will generate a site that cannot be read by third-parties. The data sent over an https connection or SSL, will be encrypted regardless of whether the certificate is signed or self-signed.
In other words, both types of certificates will encrypt the data to create a secure website.
Then Why Pay a Certificate Authority?
A certificate authority tells your customers that this server information has been verified by a trusted source. The most commonly used Certificate Authority is Verisign. Depending upon which CA is used, the domain is verified and a certificate is issued. Verisign and other more trusted CAs will verify the existence of the business in question and the ownership of the domain to provide a bit more security that the site in question is legitimate.
The problem with using a self-signed certificate is that nearly every Web browser checks that an https connection is signed by a recognized CA. If the connection is self-signed, this will be flagged as potentially risky and error messages will pop up encouraging your customers to not trust the site.
When Can You Use a Self-Signed Certificate?
Since they provide the same protection, you can use a self-signed cerificate anywhere you would use a signed certificate. But some places work better than others.
Self-signed certificates are great for testing servers. If you're creating a website that you need to test over an https connection, you don't have to pay for a signed certificate for that testing site. You just need to tell your testers that their browser may pop warning messages.
You can also use self-signed certificates for situations that require privacy, but people might not be as concerned about. For example:
Username and password forms
Collecting personal (non-financial) information
On forms where the only users are people who know and trust you
What it comes down to is trust. When you use a self-signed certificate, you are saying to your customers "trust me - I am who I say I am." When you use a certificate signed by a CA, you are saying, "Trust me - Verisign agrees I am who I say I am."
If You're Doing Ecommerce You Need a Signed Certificate
While it is possible your customers will forgive you a self-signed certificate if all they use it for is to login to your website. But if you're asking them to input their credit card or Paypal information, then you really need a signed certificate. Most people trust the signed certificates and won't do business over an HTTPS server without one. So if you're trying to sell something on your website, invest in that certificate. It's just a cost of doing business.

Ⅱ 证书签名是什么意思啊怎么签

就是你手机安装一些安装软件安装不了，它会提示需要签名或者无效什么的版。那是因为他们的权限权还不够，你去申请证书签名了，把要安装的软件签名就可以用了。
你可以去手机之家，里面有个塞班签名，一分钟就能搞定。支持在线和离线签名。
再不明白问我就好了

Ⅲ 签名和证书

简单的说，证书就是安装许可证，有了它，你就可以给你要安装的软件签名，签名后的软件才能安装到手机里
你可以把手机时间向前调半年试试，安装后再调回来

S60 第三版在安全性方面做了比较大的改善，对在系统中安装运行的第三方软件有更为严格的规定。某些涉及手机软硬件安全/个人信息安全等方面的操作被做了特别的限制（比如随手机开机自动启动就是被限制的功能之一）。应用程序要实现这些"被特别限制"了的功能就必须获得“签名”。也就是说要有人来为这个操作的安全性负责！未经任何签名的程序不能安装运行。

签名(sign)：就是使用专用工具将证书内容写入应用程序的特定字段，表示该软件已经通过了签署者的审核。签署者对该软件的安全性负责。

Ⅳ 签名证书要如何使用

证书是给软件签名用的，不用放手机里
当然，现在可以在手机里给软件签名了
工具版是signsis.sisx，安装权后
第一行是选需要签名的软件
第二行是选择key文件
第三行是选择证书文件
第四行是输入key文件密码
然后选择签名即可。
电脑上的签名工具很多了，各大智能手机论坛都有下载
例如：signsis.exe

Ⅳ 签名证书是什么来的～

代码签名复 (Code Signing) 针对网上发布控制件、应用程序、驱动程序，如设备驱动程序、硬件固化程序、病毒更新码、配置文件等代码和内容创建数字“保护膜”，以便在软件发行者和用户通过 Internet 与移动网络下载代码及内容时对他们加以保护。数字签名可验证内容的来源及完整性。其中较为知名的是VeriSign Code Signing Certificates，该公司的代码证书品种最为丰富，普及率较高。在国内可以通过VeriSign证书合作伙伴天威诚信(iTrusChina)申请获取。

Ⅵ 证书签名要怎么弄

申请证书

有些坛友在本论坛申请了证书，由于忘记申请时间等找不到。
证书查询软件只要在电脑安装此软件打开后输入串号就可以方便的找到你的曾经申请过的证书。

Ⅶ 怎样签名证书！

下载好了证书，就把.cer和.key放在内存卡上一个你记得到的地方，然后下载一个签名软件（Sign
sis，塞班网专上很属多的）安装，然后再打开它，把你要签名的软件路径找到填好，把证书和钥匙也都填好，再选择签名，它就开始签名了，签好名的软件会比原软件后缀名sis多一个x，还是放在原文件夹里面。点击它可以直接安装就行了

Ⅷ 什么是代码签名证书

代码签名证书（Code Signing Certificate）是权威CA机构发布的专门为代码和程序进行签名的数字证书专，可以验证属发布者的身份，下载软件时防止杀毒系统拦截，弹出安全警告。是进行程序分发不可或缺的证书。

Ⅸ 代码签名证书有哪几类

代码签名证书分为标准代码签名证书及EV增强型代码签名证书，区别如下：

Ⅹ 代码签名证书都有哪几种

代码签名证书主要由两种类型，OV代码签名证书和EV代码签名证书。 之前还有个人代专码签名，不过为了确属保软件的安全性，CA公司已经不再签发个人代码签名证书。代码签名证书能够对绝大部分软件进行签名，包括EXE文件、DLL文件、Andriod代码等，不需要为每个平台单独购买证书，一个公司可以用一张证书为其发行的所有软件进行签名。

除了普通的代码签名证书，还有EV代码签名。该种类型的证书具有更高的签发标准和可信度，平台对其认可度更高，如果需要支持Microsoft SmartScreen应用程序信誉功能以及对Windows 10内核驱动程序进行签名，请考虑EV代码签名证书。

解决方式：ssln可以申请多种代码签名证书的
