Connection Java-MySql : Public Key Retrieval is not allowed
I try to connect MySql database with Java using connector 8.0.11. Everything seems to be ok but I have this exception:
Exception in thread «main» java.sql.SQLNonTransientConnectionException: Public Key Retrieval is not allowed

You should add client option to your mysql-connector allowPublicKeyRetrieval=true to allow the client to automatically request the public key from the server. Note that AllowPublicKeyRetrieval=True could allow a malicious proxy to perform a MITM attack to get the plaintext password, so it is False by default and must be explicitly enabled.
you could also try adding useSSL=false when you use it for testing/develop purposes
For DBeaver users:
Right click your connection, choose «Edit Connection»
On the «Connection settings» screen (main screen) click on «Edit Driver Settings»
Click on «Connection properties»
Right click the «user properties» area and choose «Add new property»
Add two properties: «useSSL» and «allowPublicKeyRetrieval»
Set their values to «false» and «true» by double clicking on the «value» column
This is how it looks like. 
Note that this is suitable for local development only.
PortNo: 3306 can be different in your configuation
Alternatively to the suggested answers you could try and use mysql_native_password authentication plugin instead of caching_sha2_password authentication plugin.
I solve this issue using below configuration on spring boot framework
First of all, please make sure your Database server is up and running. I was getting the same error, after trying all the answers listed here I found out that my Database server was not running.
You can check the same from MySQL Workbench, or Command line using
This sounds obvious, but many times we assume that Database server is up and running all the time, especially when we are working on our local machine, when we restart/shutdown the machine, Database server will be shutdown automatically.
Подключение Java-MySql: получение открытого ключа запрещено
Я пытаюсь подключить базу данных MySql к Java с помощью коннектора 8.0.11. Вроде все в порядке, но у меня есть исключение:
Исключение в потоке «main» java.sql.SQLNonTransientConnectionException: получение открытого ключа запрещено
Вы должны добавить клиентскую опцию к вашему mysql-коннектору, allowPublicKeyRetrieval=true чтобы позволить клиенту автоматически запрашивать открытый ключ с сервера. Обратите внимание, что это AllowPublicKeyRetrieval=True может позволить вредоносному прокси-серверу выполнить MITM-атаку для получения пароля в виде открытого текста, поэтому по умолчанию он имеет значение False и должен быть явно включен.
вы также можете попробовать добавить, useSSL=false когда используете его для тестирования / разработки
Использовать jdbc url как:
PortNo: 3306 может отличаться в вашей конфигурации
Для пользователей DBeaver :
Щелкните правой кнопкой мыши ваше соединение и выберите «Редактировать соединение».
На экране «Настройки подключения» (главный экран) нажмите «Изменить настройки драйвера».
Щелкните «Свойства соединения».
Щелкните правой кнопкой мыши область «Свойства пользователя» и выберите «Добавить новое свойство».
Добавьте два свойства: useSSL и allowPublicKeyRetrieval.
Установите для них значения «ложь» и «истина», дважды щелкнув столбец «значение».
Я решаю эту проблему, используя приведенную ниже конфигурацию в Spring boot framework.
В моем случае это была ошибка пользователя. Я использовал root пользователя с неверным паролем. Я не уверен, почему я не получил ошибку аутентификации, а вместо этого получил это загадочное сообщение.
Примечание. В вашем случае имя порта 3306 может быть другим.
Эта проблема меня расстраивает, потому что вчера я мог взаимодействовать с базой данных, но, вернувшись сегодня утром, я начал получать эту ошибку.
Я попытался добавить allowPublicKeyRetrieval=true флаг, но продолжал получать ошибку.
То, что исправлено для меня, было сделано Project->Clean в Eclipse и Clean на моем сервере Tomcat. Один (или оба) исправили это.
It’s not the same without you

MySQL Public Key Retrieval is not allowed
My db server is mysql 8.0.11 and driver version 5.1.46.
When ssl is enabled, and tries to connect to the database, confluence setup reports the following.
Problem connecting to your database
But if «skip_ssl» is written to my.cnf and restarted mysql, then it shows the following error message.
Problem connecting to your database
Below is the output of logs/catalina.out
I also tried with the following connection string to disable verification and ssl

For prosperity purposes, this has been solved by downgrading mysql 8.0 to mysql 5.7.22. Confluence documentation should state that it is not compatible with mysql 8.0.

Hi Thanks for your answer. I had have same problem so the solution that’s worked for me it’s by deleting useSSL= false at all.

To change the settings on Dbeaver:
1) Right click your connection, choose «Edit Connection»
2) On the «Connection settings» screen (main screen) click on «Edit Driver Settings»
3) Click on «Connection properties»
4) Right click the «user properties» area and choose «Add new property»
5) Add two properties: «useSSL» and «allowPublicKeyRetrieval»
6) Set their values to «false» and «true» by double clicking on the «value» column
Save and re-test the connection. Hopefully it should work!

Hola que tal, a mi me a funcionado tu configuración para mi pool de conexiones, en Mysql 8.0 Corriendo en Glassfish 5 😀
Gracias, Saludos.
Hi, this my configuration, i worked in Mysql 0.8 with Glassfish 5 Server, Thanks 😀

Another solution is to fight with SSL Authentication ( not trivial ); below some url:
Also be sure you are using the latest driver for working with MySQL 8. If you at the end disable SSL, remove from your query connection the «verifyServerCertificate=false&useSSL=false» or you will get another errors ( yes it’s a jigsaw ).
MySQL Use SSL Defaults cause cert error. Wonder if a low priority feature req to add some user instruction might save frustration. #13900

With a standard localhost setup of MySQL 8.0 Community edition.
Following error occurs with the ssl defaults checked, once Use SSL is enabled.
Could not load trustJKS keystore from file:/home/
java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty
java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty
the trustAnchors parameter must be non-empty
the trustAnchors parameter must be non-empty
This occurs when the only option under ssl that has been checked is «Verify server certifcate» when «Use SSL» has been checked.
If I wasn’t used to experimenting I’d have likely grown frustrated and used a different product 😛 not that MySql doesn’t seem to be attempting to do that very thing with some of its nuisances.
I’m reporting this becomes it was a tad frustrating, and it also threw differing errors such as «Unable to to Retrieve Public Key» after a fresh reboot each time (Which was of course overcome with the available «Enable Public Key Retrieval» option enabled.)

Describe the problem you’re observing:
I am trying to remove a record from sqlite database. I use dbeaver program for all operations. So when the action is performed, following error is shown:
Steps to reproduce, if exist:
Query for table creation was this:
Insert some dummy data. Then I select a record in «data» view. Press «delete» on a keyboard. and then click «save» button below. First the warning is shown that no physical unique key is found, so he program suggests to use ALL ROW as a key. If I press cancel, then the above mentioned error is shown.
