Cryptnos will provide users with an application that will help you generate strong, pseudo-random passwords using cryptographic hashes.

Cryptnos 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.

Cryptnos 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 in an encrypted form.

FEATURES

Generates strong, pseudo-random yet repeatable “passphrases” using a variety of cryptographic hash algorithms
Supported hashing algorithms: MD5, SHA-1, SHA-256, SHA-384, SHA-512, RIPEMD-160, Whirlpool (2003 revision), and Tiger (1995 original, not “Tiger2?)
Combines site domain or mnemonic (we call it the “site token”) with the user’s “secret token” to produce a unique passphrase for every site
Further modify the generated passphrase for character class or length constraints (e.g. limit to only alphanumerics and a maximum of 12 characters)
Stores password generating parameters securely in the Windows registry using cryptographic hashes and strong AES-256 encryption
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 tooltip-based help
Automatic update checks
