❶ 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

❷ 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.
❸ 苹果软件签名证书是什么
有苹果签名才可以做ios
的内测等,看你需要哪种证书了,一般几百到上千都要,根据证书的稳定性来看的,你可以看看【ATT科技苹果签名】。这个平台的证书稳定性不错。也可以问我
❹ 手机软件签名证书怎么做
证书要来签名软件的。每一个手机串号,可以制作一个证书。 签名(sign):就是在应用程序的特定字段写入特定的标记信息,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。其中签名又大致分三种: 1. Symbian 签名。 即 Symbian(塞班)手机操作系统官方签名。通过了 Symbian 安全认证的软件才会获得 Symbian 的签名。该类软件有最高的安全级别。在手机上能正常安装/运行/且能实现软件提供的所有功能. 获得 Symbian签名需要软件作者直接和 Symbian 官方打交道,基于多方面的原因,并不是所有软件的作者都有能力获得这个认证的。 2. 作者签名。 软件作者在发布软件的时候就对软件进行了签名。这类软件可以在手机上安装运行(可能会遇到安全性警告,可跳过)。但不能实现那些“被特别限制”了的功能。如果某软件根本不涉及这类功能,那么软件作者也完全可能自己签名就行了。 还有一种可能就是软件虽然有某部分功能属于“被特别限制”的范围,但并不是主要功能。软件作者也可能发布一个“作者签名版”,这样的版本可以正常使用大部分功能,但会丧失一些特定功能。如“来电通”软件就有这样的版,几乎全部功能都可以使用,只是不能开机自启动。 3. 用户签名。 严格来说这个应该是属于“开发者签名”。因为 Symbian 为软件开发者提供一种“开发证书”,原意本来是让软件开发者作软件测试用的。这个“开发证书”是与作为测试用的机器的 IMEI 码挂钩的。使用这种证书签名的软件只能在该 IMEI 码对应的机器上使用,不能用于别的机器。 所谓的“自签名”其实就是利用了这个方式,说白了就是你说你是开发软件的,你提供你测试机器的 IMEI 码,Symbian 颁发给你一个“开发证书”,你用这个证书签名你的“测试软件”。你自己对你自己的“开发行为”负责!如此而已。 另外,开发证书自颁发日起有效期为半年.但在证书有效期内签署好了的程序的使用时限是没有限制的.
❺ 如何检查软件数字签名/证书
在.exe文件上点击右键,查看属性,里边有一栏是数字签名,点击数字签名,会看到签名人副列表,目前一般只有一个,微软有最新推出双人交叉签名。双击列表内的记录条打开,再点击“查看证书”就OK了。国内一般是用 维瑞 VeriSign或Symantec旗下的Thawte.
❻ 个人制作软件需要代码签名证书么
不论是个人还是企业制作软件,都建议使用代码签名证书。因为它的作用是让内软件开发者可以使用代码签容名证书,对其开发的软件代码进行数字签名,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。
如果软件没有使用代码签名证书,用户在下载的时候会提示该软件不安全,并且很容易受到黑客的攻击。
❼ 软件签名证书是什么有什么作用啊
软件签名证书即代码签名证书。
代码签名证书的作用如下:
1)验证软件/程序发布者回的身份
2)保持内容的真实性答和完整性
3)保护软件免受篡改和攻击
4)避免Windows发出错误消息和安全警告
5)提高客户信心,提升软件的下载、采用率和发行率
6)改善下载软件的体验
7)创建可信的软件分发渠道
❽ 代码签名证书适用于个人开发者吗
个人开发者也可以申请代码签名证书,个人代码签名证书需要验证申请者身份。不过并不是所有服务商都有个人代码签名证书,需要好好挑选。
❾ 软件的签名,证书是什么,都有什么用,我可以申请证书吗
证书是让软件有操作手机的各种权利的证明
当然可以申请

❿ 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
