Step 1. Install WhatsApp for Android

In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below is a list of programs that support the file CRYPT9.

Step 2. Create association of WhatsApp for Android with CRYPT9 files

If the application is or has been freshly installed, but the CRYPT9 file still does not use the WhatsApp for Android program, it means no association. This option is available from the level of Properties of a specific file available in the context menu. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can select the desired program.

This can be done using the application (if it provides such options) or from the WhatsApp Inc. website and install the latest version.

Step 4. Check for the following problems with the CRYPT9 file

If the above steps do not help, you can assume that the file itself is not correct. This could be due to the file itself, the cleanest issues are:

The CRYPT9 file may be unusually small compared to the original file. This suggests truncating the CRYPT9 file contents when downloading or copying. The file should be downloaded again, making sure that the process has finished correctly.
The most common cause here is computer viruses. Perform a virus scan using available and up-to-date anti-virus software. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the CRYPT9 file that we want to open. Sometimes virus-infected CRYPT9 files cannot be recovered, so make a backup in advance.
A typical compatibility error - the program does not support the older version of the CRYPT9 file. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
There can be many reasons for this. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the option of recovering data from damaged CRYPT9 files. You can restore the file from a backup or use help.
When reading, a message appears that the file was encrypted or corrupted. The encrypted CRYPT9 files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
Some of the system directories are excluded from modification. The problem is only writing to the file, not reading it. It is best to move CRYPT9 to a different directory.
This can happen on a file that does not support multiple access. Some file types can only be opened in one program at a time. Just close unnecessary programs. If the error persists after closing other programs, wait for a while. However, some background programs may block the CRYPT9 file while scanning. If the problem persists, restart the machine.
