New issue by jfcolom on void-packages repository

https://github.com/void-linux/void-packages/issues/48007

Description:
### Is this a new report?

Yes

### System Info

Void 6.6.8_1 x86_64 GenuineIntel uptodate rrFFFFF

### Package(s) Affected

x11vnc-0.9.16_6

### Does a report exist for this bug with the project's home (upstream) and/or another distro?

It works ok in Debian bullseye

### Expected behaviour

`x11vnc` can generate a password file with the option `storepasswd` among others. The password should be stored obfuscated or encrypted. In addition, `vncviewer` should be able to connect to the server when the correct password is set.

### Actual behaviour

The password is always stored in clear text.

In addition, vncviewer always get "Authentication failure: password check failed!", even when the correct password is set.

### Steps to reproduce

1. Run x11vnc to generate a password:

`x11vnc -storepasswd`

2. Input and verify the password

3. See the generated file

`cat $HOME/.vnc/passwd`

The password should appear obfuscated or encrypted. In addition, `vncviewer` should be able to connect when the correct password is set. However, the password is in clear text and the client cannot connect, even when the password is properly set in the client (tested with client from tigervnc package)
