使用 Public 和私有 JKS 文件生成密钥对
Generate KeyPair using Public and Private JKS files
是否可以使用已经生成的 Public 和私有密钥库 (JKS) 文件生成 KeyPair
以在我的应用程序中使用?
谢谢
KeyPairGenerator keyGen = KeyPairGenerator.getInstance("RSA");
keyGen.initialize(2048);
KeyPair keypair = keyGen.genKeyPair();
我想用已经生成的 RSA 2048
私钥和 public 密钥创建密钥对
您可以像下面这样使用:
public static KeyPair loadKeyStore(final File keystoreFile,
final String password, final String alias, final String keyStoreType)
throws Exception {
if (null == keystoreFile) {
throw new IllegalArgumentException("Keystore url may not be null");
}
final KeyStore keystore = KeyStore.getInstance(keyStoreType);
InputStream is = null;
try {
is = new FileInputStream(keystoreFile);
keystore.load(is, null == password ? null : password.toCharArray());
} finally {
if (null != is) {
is.close();
}
}
final PrivateKey key = (PrivateKey) keystore.getKey(alias,
password.toCharArray());
final Certificate cert = keystore.getCertificate(alias);
final PublicKey publicKey = cert.getPublicKey();
return new KeyPair(publicKey, key);
}
