Overview

Two things that should always be strong: Coffee ☕ and Passwords 🔑.

In our digital age, where data breaches and hacks have skyrocketed, robust passwords are vital for safeguarding our online accounts. Using a password manager like Bitwarden or KeePass is strongly recommended for storing and generating unique, strong passwords.
However, if you choose not to use a password manager (seriously though, consider using one), validating the strength of your passwords is crucial.

This app analyzes password patterns, predicts potential cracking times, and offers helpful suggestions for maximizing security. Additionally, it features a random password & passphrase generator that is configurable. Being entirely offline ensures that your passwords remain exclusively yours.

Verify integrity if downloaded from GitHub

To verify the integrity of the .apk/.aab files, if downloaded from GitHub, perform the following steps:

Windows

1. Open Powershell by searching for it in the Start menu OR by pressing Win + R and typing powershell
2. Change directory to the downloaded path

   cd "C:\path\to\downloaded\file"
   

   Example:

   cd "C:\Users\JohnDoe\Downloads"
   

3. Compute the SHA-256 Hash

   Get-FileHash -Algorithm SHA256 -Path "filename"
   

   Example:

   Get-FileHash -Algorithm SHA256 -Path "IYPS_v1.5.0.apk"
   

4. The computed hash value should be exactly the same as the one provided in the .sha256 file on GitHub.

Linux & macOS

1. Open terminal
2. Change directory to the downloaded path

   cd /path/to/downloaded/file
   

   Example:

   cd /home/JohnDoe/Downloads/
   

3. Compute the SHA-256 Hash

   sha256sum filename
   

   Example:

   sha256sum IYPS_v1.5.0.apk
   

4. The computed hash value should be exactly the same as the one provided in the .sha256 file on GitHub.
