扩展/续订自签名的p12证书已过期 [英] Extend/renew a p12 certificate self signed expired

问题描述

我们的adobe air应用程序p12证书已经过期.

Our adobe air application p12 certificate is already expired.

是否有任何方法可以续签相同的证书而不必创建另一个证书?

Are there any ways to renew to same certificate without having to create another one?

推荐答案

续签的证书只不过使用相同的证书签名请求(包括主题信息和公钥)，然后由证书颁发机构再次签名(在这种情况下，您又会因为它是自签名的而再次访问)，尽管过期时间已更改.

A renewed certificate is nothing else then using the same Certificate Signing Request, which includes the Subject information and the public key, and sign it again by the Certificate Agency (in this case you again because it is self-signed), although with a changed expire time.

因此，扩展证书将创建一个新证书，尽管其中包含的信息基本相同.无法以某种方式使现有证书的使用寿命更长，因为到期时间在证书内部并且包含在签名中.更改现有证书内的时间将使签名和证书无效.

So, extending a certificate will create a a new one, although with mostly the same information in it. There is no way to somehow make an existing certificate last longer, because the expiration time is inside the certificate and included in the signature. Changing the time inside an existing certificate would make the signature and thus the certificate invalid.
