Your KeePass database file is encrypted using a master key. This master key can consist of multiple components: a master password, a key file and/or a key that is protected using the current Windows user account.

If you forget/lose any of the master key components (or forget the composition), all data stored in the database is lost. There is no backdoor and no universal key that can open your database.

Master Password

If you use a master password, you only have to remember one password or passphrase (which should be good!) to open your database.

KeePass features a protection against brute-force and dictionary attacks; see the security help page for details.

Key File

A key file is a file that contains a key (and possibly additional data, e.g. a hash that allows to verify the integrity of the key). The file extension typically is 'keyx' or 'key'.

A key file must not be modified, otherwise you cannot open your database anymore. If you want to use a different key file, open the dialog for changing the master key (via 'File' → 'Change Master Key') and create/select the new key file.

Two-factor protection. A key file is something that you must have in order to be able to open the database (in contrast to a master password, which you must know). If you use both a key file and a master password, you have a two-factor protection: possession and knowledge.

Location. As mentioned above, the idea of a key file is that you have something. If an attacker obtains both your database file and your key file, then the key file provides no protection. Therefore, the two files must be stored in different locations. For example, you could store the key file on a separate USB stick.

Hiding the location. The key file content must be kept secret, not its location (file path/name). Trying to hide the key file (e.g. by storing it among a thousand other files, in the hope that an attacker does not know which file is the correct one) typically does not increase the security, because it is easy to find out the correct file (e.g. by inspecting the last access times of files, lists of recently used files of the operating system, file system auditing logs, anti-virus software logs, etc.).

KeePass has an option for remembering the paths of key files, which is turned on by default; turning it off typically just decreases the usability without increasing the security. This option only affects KeePass itself (i.e. turning it off does not prevent the operating system or other software from remembering the paths). If you only want to prevent a key file from appearing in the recently used files list of Windows (which does not really affect the security) after selecting it in KeePass, consider turning on the option for entering the master key on a secure desktop (KeePass will then show a simpler key file selection dialog that does not add the file to the recently used files list of Windows).

Backup. You should create a backup of your key file (onto an independent data storage device). If your key file is an XML file (which is the default), you can also create a backup on paper (KeePass 2.x provides a command for printing a key file backup in the menu 'File' → 'Print'). In any case, the backup should be stored in a secure location, where only you and possibly a few other people that you trust have access to. More details about backing up a key file can be found in the ABP FAQ.

Reuse. You can use one key file for multiple database files. This can be convenient, but please keep in mind that when an attacker obtains your key file, you have to change the master keys of all database files protected with this key file.

KeePass 1.x Only

In order to reuse an existing key file, click on the button with the 'Save' icon in the master key creation dialog and select the existing file. After accepting the dialog, KeePass will ask you whether to overwrite or reuse the file (see screenshot).

KeePass 2.x Only

In order to reuse an existing key file, click on the 'Browse' button in the master key creation dialog.

Windows User Account

KeePass 1.x Only

KeePass 1.x does not support encrypting databases using Windows user account credentials. Only KeePass 2.x and higher support this.

KeePass 2.x Only

KeePass can make the database dependent on the current Windows user account. If you enable this option, you can only open the database when you are logged in as the same Windows user when creating the database.

Warning

Be very careful with using this option. If your Windows user account gets deleted, you won't be able to open your KeePass database anymore. Also, when using this option at home and your computer breaks (hard disk damaged), it is not enough to just create a new Windows account on the new installation with the same name and password; you need to copy the complete account (i.e. SID, ...). This is not a simple task, so if you don't know how to do this, it is highly recommended that you don't enable this option. Detailed instructions how to recover a Windows user account can be found here: 'Recover Windows User Account Credentials' (a short technical tutorial can be found in a Microsoft TechNet article: 'How to recover a Vault corrupted by lost DPAPI keys').

You can change the password of the Windows user account freely; this does not affect the KeePass database. Note that changing the password (e.g. a user using the Control Panel or pressing Ctrl+Alt+Delete and selecting 'Change Password') and resetting it to a new one (e.g. an administrator using a NET USER <User> <NewPassword> command) are two different things. After changing your password, you can still open your KeePass database. When resetting the password to a new one, access usually is not possible anymore (because the user's DPAPI keys are lost), but there are exceptions (for example when the user is in a domain, Windows can retrieve the user's DPAPI keys from a domain controller, or a home user can use a previously created Password Reset Disk). Details can be found in the MSDN article 'Windows Data Protection' and in the support article 'How to troubleshoot the Data Protection API (DPAPI)'.

If you decide to use this option, it is highly recommended not to rely on it exclusively, but to additionally use one of the other two options (password or key file).

Instead of backing up the Windows user account, you can alternatively create an unencrypted backup of the key using the 'Windows User Account Backup and Restore Utility'. As such a backup is not encrypted, it must be stored in a secure location.

Protection using user accounts is unsupported on Windows 98 / ME.

For Administrators: Specifying Minimum Properties of Master Keys

Administrators can specify a minimum length and/or the minimum estimated quality that master passwords must have in order to be accepted. You can tell KeePass to check these two minimum requirements by adding/editing appropriate definitions in the INI/XML configuration file.

KeePass 1.x Only

The value of the KeeMasterPasswordMinLength key can contain the minimum master password length in characters. For example, by specifying KeeMasterPasswordMinLength=10, KeePass will only accept master passwords that have at least 10 characters.

The value of the KeeMasterPasswordMinQuality key can contain the minimum estimated quality in bits that master passwords must have. For example, by specifying KeeMasterPasswordMinQuality=64, only master passwords with an estimated quality of at least 64 bits will be accepted.

I notice you’ve referenced a specific file: Jackie Chan Stuntmaster -USA-.chd. This appears to be a CHD (Compressed Hunks of Data) file for the North American version of the PlayStation game Jackie Chan Stuntmaster.

If you’re asking for a deep content analysis of this file (e.g., file structure, data integrity, hidden assets, audio/video streams, or reverse-engineering details), I can help explain what such an analysis would involve, but I cannot directly access, scan, or extract content from the file on your system.

Here’s what a technical deep dive into this .chd could cover:

CHD structure – The file likely contains a raw disc image (CD-ROM) of the game, compressed with lossless CHD algorithms (huffman, FLAC for audio, etc.).
Extraction – Using chdman (from MAME tools) to decompress to .bin/.cue or .iso.
File system – The PlayStation CD-ROM has a specific layout (ISO 9660 + CD-DA + PlayStation executable). Tools like isoinfo, 7zip (with CHD plugin), or jPSXdec can inspect.
Game data – Looking for:
- SLUS_010.30 (main executable)
- STR video files (FMVs)
- VAG audio, XA streams
- TIM images, background layouts
- Level scripts, collision data for stunts
Potential hidden content – Sometimes prototype leftovers, debug menus, unused voice lines, or region differences exist. For Jackie Chan Stuntmaster, known regional variations include minor text/voice changes.

If you want to verify integrity:

Compare SHA-1 of the decompressed disc image against known Redump database: 7faefb3ef58d10ba2c5faa2a17ec2fe7a668398f (USA version)

If you meant something else by “deep content” (e.g., extracting all game assets programmatically, modding the game, or analyzing the game’s engine), please clarify.

Note: Please ensure you own a legitimate copy of the game if you are working with this file, as distributing copyrighted game data is illegal.

For Steam Deck (Proton/Linux)

Download the .chd file.
Place it in /home/deck/ROMs/psx/
Open EmuDeck (or DuckStation flatpak).
Scan the directory. DuckStation will automatically recognize the hash.
Pro tip: Enable "Rewind" feature – it makes the difficult jumping sections manageable.

Why Preservation Matters

Physical PS1 discs suffer from "disc rot" (oxidation of the reflective layer). Jackie Chan Stuntmaster is a 25-year-old title. Physical copies on eBay sell for $80 to $150 USD for a clean copy. The CHD ensures that the game’s stuntman animations, Jackie’s voice work, and the hidden outtakes will exist long after the last CD becomes unreadable.

Why CHD instead of BIN/CUE?

Traditionally, PlayStation games come as a .bin (raw data) and .cue (table of contents) file. A typical Stuntmaster BIN/CUE folder is roughly 650 MB. However, the CHD version of the same game is often 200 MB to 300 MB. Wire fu : A style of martial arts

Part 5: Preservation & Legal Status

Discussing Jackie Chan Stuntmaster -USA-.chd inevitably raises the question of legality.
