1. 代碼簽名證書有什麼作用

  1. 保護發行商身份來安全

    通過對代源碼進行數字簽名來標識發行商身份,可以保證發行商身份和代碼在簽名之後不被非法篡改。篡改代碼或捆綁木馬、惡意攻擊程序、修改發行商身份信息等任何對已發行代碼進行編輯的操作都會導致軟體簽名信息失效,失去相應安全應用授權。

  2. 防止用戶下載有害文件

    代碼簽名 針對網上發布控制項、應用程序、驅動程序,如設備驅動程序、硬體固化程序、病毒更新碼、配置文件等代碼和內容創建數字「保護膜」,以便在軟體發行者和用戶通過 Internet 與移動網路下載代碼及內容時對他們加以保護。給代碼添加數字簽名可驗證內容的來源及完整性,促進軟體的下載使用與分發。減少錯誤消息和安全警告,增加軟體發行、下載。

2. 代碼簽名證書有哪些簽名種類

代碼簽名證書是提供給軟體開發者,對其開發的軟體代碼進行數字簽名的數字證書,用於驗證開發者身份真實性、保護代碼的完整性。用戶下載軟體時,能通過數字簽名驗證軟體來源可信,確認軟體沒有被非法篡改或植入病毒木馬,保護用戶不會被病毒、惡意代碼和間諜軟體所侵害,也保護了軟體開發者的利益,讓軟體能在互聯網上快速安全地發布。

軟體開發商可以使用代碼簽名證書來簽名內核代碼 .sys文件、ActiveX文件、 .exe 和 .dll 文件、Java Applets、J2ME MIDlet、Office宏文件和運行移動操作系統(Windows Mobile 和 Symbian)的智能手機開發的移動應用軟體。

代碼簽名證書的一般分類

1.標准代碼簽名證書

代碼簽名證書(Code Signing Certificates)是為軟體開發者提供的一個理想的解決方案,使得軟體開發者對其軟體代碼進行數字簽名,確保用戶下載的內容來自所聲明的來源。

2.EV增強型代碼簽名證書

EV代碼簽名證書(Extended Validation Code Signing Certificates)在源代碼簽名證書基礎上加強了對企業身份的驗證。

二者的功能區分如表中所述:

3. 協議書上當事人的簽名不對還是別人代簽的可以當證據嗎

如果能證明當初是共同出資,則現在拆遷補償款應當由出資人共有。

簽字協議有效,未簽字人如果能證明出資也應當享有份額,不管簽沒簽字出資人都應當享有一定份額。

4. 簽名的本人證書是什麼意思

支付時您需要插入盾並根據提示輸入U盾證書密碼才能完成交易。若您在支付時插入U盾卻選擇不到證書或系統檢測不到證書,這說明您的u盾沒有與計算機連接好,請您拔出u盾後重新插入(建議插在主板上的USB介面,而不要使用前置的介面),如果KEY上的指示燈長亮,那麼就說明連接好了,您可以重新進行操作。若仍不可以,那麼請您按以下步驟進行操作:(1)重新安裝對應品牌的u盾驅動程序。 (2)查看您的系統是否已打全補丁,如果沒有,請使用WINDOWS的UPDATE功能進行升級。 (3)如果您的系統為2000或XP,請您選擇「控制面板」中的「管理工具」下的「服務」,查看SMART CARD是否啟用,如未啟用,請您啟用。重新安裝U盾證書驅動程序的方法:1、拔下U盾客戶證書,卸載原證書驅動程序;2、使用系統管理員許可權重新登錄windows;3、請登錄工行門戶網站 www.icbc.com.cn,點擊「個人網上銀行登錄」下方的「安裝」。進入下一個頁面後,下載並安裝對應品牌的「U盾」驅動程序。4、重新啟動電腦後再連接U盾客戶證書。

5. 簽名證書與自簽名證書的區別

簽名證書:由權威頒發機構頒發給伺服器或者個人用於證明自己身份的東西,默認客戶端都是信任的。主要目的是用來加密和保證數據的完整性和不可抵賴性

自簽名證書:由伺服器自己頒發給自己,用於證明自己身份的東西,非權威頒發機構發布,默認客戶端都是不信任的,主要目的是用來加密和保證數據的完整性和不可抵賴性,與簽名證書相同.

詳細具體解釋見下面英文。
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. 怎樣簽名證書!

下載好了證書,就把.cer和.key放在內存卡上一個你記得到的地方,然後下載一個簽名軟體(Sign
sis,塞班網專上很屬多的)安裝,然後再打開它,把你要簽名的軟體路徑找到填好,把證書和鑰匙也都填好,再選擇簽名,它就開始簽名了,簽好名的軟體會比原軟體後綴名sis多一個x,還是放在原文件夾裡面。點擊它可以直接安裝就行了

7. 合同開頭的簽名和身份證號碼可以別人代簽嗎

別人代簽也是需要授權委託書之類的書面證明材料,才會找別人代簽的。

8. 委託書代簽名

個人委託書範本委託人: 性別: 身份證號:被委託人: 性別: 身份證編回號:本人工作繁忙,不能親答自辦理XXX的相關手續,特委託____________作為我的合法代理人,全權代表我辦理相關事項, 對委託人在辦理上述事項過程中所簽署的有關文件,我均予以認可,並承擔相應的法律責任.委託期限:自簽字之日起至上述事項辦完為止.委託人:

9. 送達回證不是本人簽字代簽人應負什麼責任

代簽人無須負法律責任。首先簽收法律文書是你所說的本人的法定義務,該人沒有拒收的理由。其次,代收人只有在法律認可的情況下才起到簽收的作用。再次,代收人無正當理由也不得拒收,否則也會有相應法律後果。
