Project description

SQL Developer password decryptor


A simple script to decrypt stored passwords from the Oracle SQL Developer IDE.


  • Support old v3 and current v4 passwords
  • Comes in 2 flavors: a Jython and a Python script


Version 3

Passwords are stored encrypted in the connections.xml file in those locations:

  • Windows: %APPDATA%\SQL Developer\system<VERSION>\o.jdeveloper.db.connection.<VERSION>\connections.xml
  • Linux: ~/.sqldeveloper/system<VERSION>/o.jdeveloper.db.connection.<VERSION>/connections.xml

Version 4

Passwords are stored encrypted in the aforementioned connections.xml file but the encryption key by default uses a machine-unique value in the product-preferences.xml file accessible here:

  • Windows: %APPDATA%\SQL Developer\system<VERSION>\o.sqldeveloper.<VERSION>\product-preferences.xml
  • Linux: ~/.sqldeveloper/system<VERSION>/o.sqldeveloper.<VERSION>/product-preferences.xml

When exporting one or more connections in version 4, the user is asked to type a password: that password is then used as a key to encrypt the entries instead of the value.


$ python -h
Usage: [options]
Version: 1.1

  -h, --help            show this help message and exit

  v3 and v4 parameters:
                        (mandatory): password that you want to decrypt. Ex. -p

  v4 specific parameters:
    -d DB_SYSTEM_ID_VALUE, --db-system-id-value=DB_SYSTEM_ID_VALUE
                        (mandatory for v4): machine-unique value of
                        "" attribute in the "product-
                        preferences.xml" file, or the export file encryption
                        key. Ex: -d 6b2f64b2-e83e-49a5-9abf-cb2cd7e3a9ee


v3 password

$ jython sqldeveloperpassworddecryptor.jy -p 054D4844D8549C0DB78EE1A98FE4E085B8A484D20A81F7DCF8
[+] encrypted password: 054D4844D8549C0DB78EE1A98FE4E085B8A484D20A81F7DCF8

[+] decrypted password: password

v4 password

$ python -d 6b2f64b2-e83e-49a5-9abf-cb2cd7e3a9ee -p Shz0tQgqkuAfLy65s21gTVD7wacDYwG6
[+] encrypted password: Shz0tQgqkuAfLy65s21gTVD7wacDYwG6
[+] value: 6b2f64b2-e83e-49a5-9abf-cb2cd7e3a9ee

[+] decrypted password: s4gswagswaag!5465636MP

Dependencies and installation

  • For the Jython version: well, only Jython (apt-get install jython or download it here)
  • For the Python version:
    • The easiest way to setup everything: pip install sqldeveloperpassworddecryptor and then directly use $ sqldeveloperpassworddecryptor
    • Or manually install PyCryptodome: pip install pycryptodomex


  • version 2.0 - 11/11/2020: Python 3 support
  • version 1.2 - 07/14/2017: replacing PyCrypto by PyCryptodomex for these reasons
