java-如何在密钥库中存储密钥

您还需要提供私钥条目的证书（公钥）。对于由CA签名的证书，链是CA的证书和最终证书。对于自签名证书，您只有自签名证书。
示例：

KeyPair keyPair = ...;//You already have this  X509Certificate certificate = generateCertificate(keyPair);  KeyStore keyStore = KeyStore.getInstance("JKS");  keyStore.load(null,null);  Certificate[] certChain = new Certificate[1];  certChain[0] = certificate;  keyStore.setKeyEntry("key1", (Key)keyPair.getPrivate(), pwd, certChain);

要生成证书，请点击以下链接：
示例：

public X509Certificate generateCertificate(KeyPair keyPair){     X509V3CertificateGenerator cert = new X509V3CertificateGenerator();      cert.setSerialNumber(BigInteger.valueOf(1));   //or generate a random number     cert.setSubjectDN(new X509Principal("CN=localhost"));  //see examples to add O,OU etc     cert.setIssuerDN(new X509Principal("CN=localhost")); //same since it is self-signed     cert.setPublicKey(keyPair.getPublic());     cert.setNotBefore(<date>);     cert.setNotAfter(<date>);     cert.setSignatureAlgorithm("SHA1WithRSAEncryption");       PrivateKey signingKey = keyPair.getPrivate();       return cert.generate(signingKey, "BC");  }
