About Cryptnos

Cryptnos is a multi-platform, Open Source application for generating strong, pseudo-random passwords using cryptographic hashes. It combines a unique "site token" such as a website domain name with a master password and runs this data through a cryptographic hash algorithm to produce a password that is unique, lengthy, seemingly random yet completely repeatable. Unlike similar products, however, it is exceedingly flexible. It is not a browser plugin, so it can be used with other applications outside the Web. It provides unparalleled versatility by letting you specify the cryptographic hash to use, how many iterations of the hash to perform, what characters to include, and how long the final password should be. Best of all, it is exceedingly secure. Your master and generated passwords are *NEVER* stored, and the parameters to recreate your passwords are stored using strong AES-256 encryption.

Cryptnos is currently available for Microsoft Windows via the .NET Framework 2.0, as well as for Google Android powered devices. A version for pure Java is under development, as well as an HTML/JavaScript online version that should work with any browser.

Selected Features:

* Supported hashing algorithms: MD5, SHA-1, SHA-256, SHA-384, SHA-512, RIPEMD-160, Whirlpool (2003 revision), and Tiger (1995 original, not "Tiger2")
* Further modify the generated password for character class or length constraints (e.g. limit to only alphanumerics and a maximum of 12 characters)
* Cross-platform import/export mechanism allows parameters to be copied from one instance of Cryptnos on one machine to another instance on another machine, strongly encrypting the export file using AES-256
* Integrated help

See our website for more detailed information (and replies to your comments!).

The functionality of Cryptnos may be enhanced if any of the following file manager and bar code scanning applications are installed. These apps are not required for Cryptnos to operate, but their presence will enable additional functionality.
* OI File Manager
* AndExplorer
* ES File Explorer
* ZXing Barcode Scanner
* QR Droid / QR Droid Private

Cryptnos is a fantastic way to allow you to create maximum security-strength, unique passwords for every website you visit. You set the rules to generate passwords for a certain site, and all you need to remember is one master password! Cryptnos remembers and keeps track of they keywords/addresses associated with any given website. You can save and export your passwords in encrypted form to export and save to Cryptnos on other devices as well! (Saving locally and/or to the cloud: DropBox, Google Drive, OneDrive, etc) Cryptnos is mult-platform (Windows, Android, Web-based), so no matter where you are, you can re-generate your unique and secure password, for each site you visit. Stop using the same, insecure passwords for multiple sites, so there is no worry about your a security breach and having your password leaked that can compromise all sites that may share the same password. Check it out! It's free, safe, and the best solution for secure passwords I've found!

1. With what password is database containing "site tokens" etc is encrypted? 2. HMAC options like H512 (For HMAC-SHA512) etc are desired. 3. Edit option should also alow "site token" entry to be edited. If I change my password for site token "Yahoomail main" later, I can edit the site token as "Yahoomail main 02" etc. 4. Add another parameter box "append special characters" eg #& (required by some websites) 5. Use keyboard like K2PA in Keepass2Android app to avoid clipboard attacks.

by U####:

Now all have to remember is my one password and what I called each site. Crptnos does the rest without storing my passwords anywhere. Fantastic.

S70%
by S####:

This application creates strong site specific random passwords from a combination of user defined variables and a common known secret. By storing only the defined variables for each site this program allows you to have strong per site password where you only have to remember a single secret to generate each password. The app is easy to use; allowing copy/pasting of long passwords into apps/websites.

I absolutely love this app! This app is the ullimate password encryptor and password generator on the Android Market, and on the computer.Store files on the sd card with an encrypted password or store them to your dropbox cloud, and have them available on all of the devices you use. This app is a must if you're concerned about securing your passwords with the highest level of security and encryption!

No net access needed; won't store pwds, just pwd gen params; not limited to a master pwd; can use single master and still get diff pwds per site.
