1.

What PostgreSQL versions are supported by the program?

The program supports data import and recovery of the PostgreSQL passwords for the following versions:

7.2, 7.3, 7.4,
8.0, 8.1, 8.2, 8.3, 8.4,
9.0, 9.1, 9.2, 9.3, 9.4, 9.5, 9.6.

2.

What are system requirements?

System requirements:

  • any operating system with Oracle JRE 8 installed;
  • minimum of 1 Gb RAM;
  • free 18 Mb hard disk space (plus the space required for JRE installation);
  • minimum of 800x600 screen resolution.

3.

What access rights are required for importing data from a database?

The source data for password recovery is stored in the table or view pg_shadow. Only the user postgres has the required access by default.

To import the data, specify either user postgres or one of the users with access to this data.

4.

Can rainbow tables be used for password recovery?

Now there are no rainbow tables files for PostgreSQL and applications for their creation. Precomputed hashes attack is not supported in the current version of the program.

The user name is used in the algorithm for calculating PostgreSQL passwords hashes. Thus, it is ineffective to use the existing MD5 rainbow tables files.

5.

What are the limitations of the evaluation version?

The evaluation version has the following functional limitations:

  • only the first character of the recovered password is shown;
  • in hybrid attack, the quantity of added characters is limited;
  • the character set is limited to A-Z characters;
  • in brute force attack, the possible maximum password length is limited.
