Question

我们购买了用于签署applet的代码签名证书，但签署applet时出现以下错误。

    C:\CM\WEB-INF>jarsigner -keystore code_signing.keystore C:\CM\SweetApplet.jar code_signing_real
Enter Passphrase for keystore:
    jarsigner: Certificate chain not found for: code_signing_real.  code_signing_real must reference a valid KeyStore key entry containing a private key and corresponding public key certificate chain.

我们的证书不正确吗？这是以下问题的证书。错误消息似乎表明证书必须包含私钥，但我们不明白这是怎么回事，因为私钥永远不会暴露给除我们以外的任何人。

C:\CM\WEB-INF>keytool -list -keystore code_signing.keystore -alias code_signing_real -v
Enter keystore password:

Answer 1

它并不表示证书必须包含私钥。证书不包含私钥。再读一遍。它说密钥条目必须包含私钥和证书。

所以你构建了这个KeyStore，它是无效的。您可能只是将签名证书导入到新的KeyStore中，或者使用新别名。您必须将其导入到私钥的原始KeyStore中，并使用与私钥相同的别名。

您还必须将证书链作为可信CA证书导入另一个别名。

此代码签名证书是否对签名applet有效？
