我正在尝试验证证书的公钥.使用以下命令将证书导入密钥库:

keytool -importcert -file cert.cer -keystore kstore.jks -alias mycert -storepass changeit

这是我用来验证公钥的java代码:

File keyStore = new File("kstore.jks");
String keyStorePassword = "changeit";
KeyStore ks = null;
try {
   ks = KeyStore.getInstance("jks");
   ks.load(keyStore.toURI().toURL().openStream(), keyStorePassword.toCharArray());
} catch (Exception e) {
   e.printStackTrace();
} 

try {
   Certificate cert = ks.getCertificate("mycert");
   PublicKey pk = cert.getPublicKey();
   cert.verify(pk);
   //cert.verify(pk, "SunRsaSign");
   System.out.println("Keys verified");
} catch (Exception e) {
   e.printStackTrace();
}

我得到的例外是:

java.security.SignatureException: Signature does not match.
   at sun.security.x509.X509CertImpl.verify(X509CertImpl.java:446)
   at sun.security.x509.X509CertImpl.verify(X509CertImpl.java:389)
   at VerifyEBXMLSignature.runIt3(VerifyEBXMLSignature.java:62)
   at VerifyEBXMLSignature.main(VerifyEBXMLSignature.java:41)

证书包含公钥,我无权访问私钥.是否可以根据我导入密钥库的证书验证公钥？公钥来自证书本身,所以它应该是正确的.

我还应该在证书上找到什么？

我刚刚得到了一些关于证书的iformation:它是从私钥导出的.这个过程中有什么可能做错了吗？
