WORK IN PROGRESS - Feel free to raise any issues, features or improvements on GitHub!

Hash-gen aims to find the matching hex value for a given hash, therefore finding out the unencrypted/original value of the hash. ![alt tag](https://s2.postimg.org/74q9wpg7t/Screen_Shot_2017_03_01_at_20_57_40.png) ## Example Take the number, `500`. Convert `500` to hex and you will get `1f4`. Encrypt `1f4` with sha256 and you will get the following hash: `10be707c02c8eafff11f843178cc5c86381b2d31d3569b268ad4d0a4dc890c7d` Now, say you are trying to find the value behind this hash. How would Hash-gen do this? Just run the following: ```bash $ hash-gen -t 10be707c02c8eafff11f843178cc5c86381b2d31d3569b268ad4d0a4dc890c7d -s 5 -d 1 -h sha256 -V --log ``` After running this command, Hash-gen would set the target hash target to `10be707c02c8eafff11f843178cc5c86381b2d31d3569b268ad4d0a4dc890c7d`, starting at `5` it would increment by `1`, each time converting the number to hex, hashing the hex and checking to see if the hash is equal to the `target` hash. For example: ```bash Int: 5 Hex: 5 Hash: ef2d127de37b942baad06145e54b0c619a1f22327b2ebbcfbec78f5564afe39d ... Int: 170 Hex: aa Hash: 961b6dd3ede3cb8ecbaacbd68de040cd78eb2ed5889130cceb4c49268ea4d506 Int: 171 Hex: ab Hash: fb8e20fc2e4c3f248c60c39bd652f3c1347298bb977b8b4d5903b85055620603 Int: 172 Hex: ac Hash: f45de51cdef30991551e41e882dd7b5404799648a0a00753f44fc966e6153fc1 Int: 173 Hex: ad Hash: 70ba33708cbfb103f1a8e34afef333ba7dc021022b2d9aaa583aabb8058d8d67 Int: 174 Hex: ae Hash: f9a00f43e97e3966bb846e76b6795e11512c3bbfa787e6b70e0310c7b9346b98 Int: 175 Hex: af Hash: 503126878d17fcd6bde7df320ff6eb7c278a1c42f30014a03b17f3dd0c023c1d ``` If Hash-gen does find a match it will output something similar to this: ```bash -- A MATCH FOR YOUR HASH VALUE HAS BEEN FOUND -- Writing to /Users/ryan/Documents/hash_logs/sha256-54048.txt... Successfully saved match. ``` Locate the .txt file, if the `--log` argument was passed, this file will contain all the previous hex/hash pairs. You may need to run a search on the file for the target hash. Example contents of .txt file: ``` sha256 hash log. Matched On Int: 500 Hex Value: 1f4 Hash Type: sha256 Hash: 10be707c02c8eafff11f843178cc5c86381b2d31d3569b268ad4d0a4dc890c7d ``` Congratulations! You now know that your `target hash` has the hex value of `1f4`. ## 1. Install hash-gen ```bash $ npm install --global hash-gen ``` Ensure you are using node version 6 or above. Double check the installation has gone smoothly by simply running: ```bash $ hash-gen ``` If it has, you should see the following message: ```bash Hash-gen has been successfully installed! Time to get hashing. ``` ## 2. Start Hashing! ```bash $ hash-gen -h sha256 -t bf9949911bad9ad71e2b8d4904ea4ffd386a6a8fa03e68e1d2ac738fd1d8be4d -s 5 -d 1 -V -l ``` ### Hash Matching ``` -t, --target The hash you are trying to find a match for -h, --hash Type of hash e.g sha256, sha512 etc. (sha256 is default) -s, --start The number you would like to start at (1 is default) -d, --delay Delay in milliseconds between each hash (5 is default, 1 is minimum value) -l, --log Keep a log of all created hashes to file (Can slow hash generation when ON) -V, --Verbose Verbose output (Shows hex & hash) --ssh Enables SSH mode (No console output at all) - Highly recommended when running Hash-gen on a VPS ``` ### Hash Creation ``` -c, --create Only used when creating a hash. The value you would like to hash (e.g. password) -h, --hash Type of hash e.g sha256, sha512 etc. (sha256 default) --digest hex, base64, utf8, latin1 (hex default) ``` ### Global ``` --help Shows help for Hash-gen ``` ## Currently Supported hashes `md4`, `md5`, `mdc2`, `sha`, `sha1`, `sha224`, `sha256`, `sha384`, `sha512`, `dss1`, `ripemd`, `ripemd160`, `rmd160`, `whirlpool` More hashing algorithm's coming soon!
