Re: #7076 - Keychain access on Mac

Hi Hackers,

Issue #7076 has been reported by many Mac users. Issue has popped up when python binary version is changed for the pgadmin.

To save server passwords, pgadmin uses os level secret storage (in case of Mac it is keyring) and adds an entry for each save password. Whenever the python binary version is changed, keychain (python lib used to access keychain) asks for a password 2 times for accessing each entry. If you have 10 servers, then it will ask for 20 times.

To fix the issue, pgadmin will follow the same approach as chrome. 

1.An encryption key will be auto-generated and will be stored in the keychain.

2.Whenever save password request is received, encryption key will be used to encrypt password and encrypted password will be saved in the pgadmin database.

3.Similarly, while retrieving the password, encryption will be pulled from the keychain and will be used to decrypt the password.

This will reduce password asks to 2 times on python binary version change.
