Jkain is a Servers & Network software developed by Tim Jansson. After our trial and test, the software is proved to be official, secure and free. Here is the official description for Jkain:
EditByBSEditor: Jkain is a free (as in free beer) fast hash reverser (MD5 & SHA-1) designed primarily for security analysts and penetration testers for risk assessment support. From ordinary databases where the passwords are stored hashed but unsalted Jkain will most likely be able to reverse about 50-75% of the hashed passwords in just matters of seconds, this because Jkain is using online rainbow tables.
In addition to reversal of hashes Jkain has a set of other functions:
* Clipboard hashing/reversing via Tray Icon. * Hash extractor - Extract hashes from files/dumps into a custom format. * Hasher - Calculate the MD5/SHA-1 hash out of a text string. * History - View previously reversed hashes. you can free download Jkain 1.0.0 now.
