1. 代码签名证书有什么作用
保护发行商身份来安全
通过对代源码进行数字签名来标识发行商身份,可以保证发行商身份和代码在签名之后不被非法篡改。篡改代码或捆绑木马、恶意攻击程序、修改发行商身份信息等任何对已发行代码进行编辑的操作都会导致软件签名信息失效,失去相应安全应用授权。
防止用户下载有害文件
代码签名 针对网上发布控件、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。给代码添加数字签名可验证内容的来源及完整性,促进软件的下载使用与分发。减少错误消息和安全警告,增加软件发行、下载。
2. 代码签名证书有哪些签名种类
代码签名证书是提供给软件开发者,对其开发的软件代码进行数字签名的数字证书,用于验证开发者身份真实性、保护代码的完整性。用户下载软件时,能通过数字签名验证软件来源可信,确认软件没有被非法篡改或植入病毒木马,保护用户不会被病毒、恶意代码和间谍软件所侵害,也保护了软件开发者的利益,让软件能在互联网上快速安全地发布。
软件开发商可以使用代码签名证书来签名内核代码 .sys文件、ActiveX文件、 .exe 和 .dll 文件、Java Applets、J2ME MIDlet、Office宏文件和运行移动操作系统(Windows Mobile 和 Symbian)的智能手机开发的移动应用软件。
代码签名证书的一般分类
1.标准代码签名证书
代码签名证书(Code Signing Certificates)是为软件开发者提供的一个理想的解决方案,使得软件开发者对其软件代码进行数字签名,确保用户下载的内容来自所声明的来源。
2.EV增强型代码签名证书
EV代码签名证书(Extended Validation Code Signing Certificates)在源代码签名证书基础上加强了对企业身份的验证。
二者的功能区分如表中所述:
3. 协议书上当事人的签名不对还是别人代签的可以当证据吗
如果能证明当初是共同出资,则现在拆迁补偿款应当由出资人共有。
签字协议有效,未签字人如果能证明出资也应当享有份额,不管签没签字出资人都应当享有一定份额。
4. 签名的本人证书是什么意思
支付时您需要插入盾并根据提示输入U盾证书密码才能完成交易。若您在支付时插入U盾却选择不到证书或系统检测不到证书,这说明您的u盾没有与计算机连接好,请您拔出u盾后重新插入(建议插在主板上的USB接口,而不要使用前置的接口),如果KEY上的指示灯长亮,那么就说明连接好了,您可以重新进行操作。若仍不可以,那么请您按以下步骤进行操作:(1)重新安装对应品牌的u盾驱动程序。 (2)查看您的系统是否已打全补丁,如果没有,请使用WINDOWS的UPDATE功能进行升级。 (3)如果您的系统为2000或XP,请您选择“控制面板”中的“管理工具”下的“服务”,查看SMART CARD是否启用,如未启用,请您启用。重新安装U盾证书驱动程序的方法:1、拔下U盾客户证书,卸载原证书驱动程序;2、使用系统管理员权限重新登录windows;3、请登录工行门户网站 www.icbc.com.cn,点击“个人网上银行登录”下方的“安装”。进入下一个页面后,下载并安装对应品牌的“U盾”驱动程序。4、重新启动电脑后再连接U盾客户证书。
5. 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.
6. 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

7. 合同开头的签名和身份证号码可以别人代签吗
别人代签也是需要授权委托书之类的书面证明材料,才会找别人代签的。
8. 委托书代签名
个人委托书范本委托人: 性别: 身份证号:被委托人: 性别: 身份证编回号:本人工作繁忙,不能亲答自办理XXX的相关手续,特委托____________作为我的合法代理人,全权代表我办理相关事项, 对委托人在办理上述事项过程中所签署的有关文件,我均予以认可,并承担相应的法律责任.委托期限:自签字之日起至上述事项办完为止.委托人:
9. 送达回证不是本人签字代签人应负什么责任
代签人无须负法律责任。首先签收法律文书是你所说的本人的法定义务,该人没有拒收的理由。其次,代收人只有在法律认可的情况下才起到签收的作用。再次,代收人无正当理由也不得拒收,否则也会有相应法律后果。
