Tool to decrypt / encrypt with hash functions (MD5, SHA1, SHA256, bcrypt, etc.) automatically. The hashing of a given data creates a fingerprint that makes it possible to identify the initial data with a high probability (very useful in computer science and cryptography).
Answers to Questions
MD5 Decrypt This site allows you to encrypt or decrypt any md5 hash, we have our own database with more than 10 million keys, also we look for your hash on 23+ others web sites. On this section you can also create a new md5 hash base on any text or just apply another algorithm to generate hashes. Md5 (Message Digest 5) is a cryptographic function that allows you to make a 128-bits (32 caracters) 'hash' from any string taken as input, no matter the length (up to 2^64 bits).This function is irreversible, you can't obtain the plaintext only from the hash. The only way to decrypt your hash is to compare it with a database using our online decrypter. MD5 means a 128-bit encryption algorithm, generating a 32-character hexadecimal hash. This algorithm is not reversible, ie it is normally impossible to find the original word from the md5 hash. Our tool uses a huge database in order to have the best chance possible to trace the decrypted text. In Windows Vista and above, LM has been disabled for inbound authentication. Windows NT-based operating systems up through and including Windows Server™ 2003 store two password hashes, the LAN Manager (LM) hash and the Windows NT hash. Starting in Windows Vista™, the capability to store both is there, but one is turned off by default. Windows encrypts the login password using LM or NTLM hash algorithm. Since these are one way hash algorithms. We cannot directly decrypt the hash to get back the original password. In such cases 'Windows Password Kracker' can help in recovering the windows password using the simple dictionary crack method.
How to calculate/encode a hash?
The hash functions use computer data (in binary format) and apply nonlinear and non-reversible functions with a strong avalanche effect (the result is very different even if the input data is very similar). The fingerprint is usually returned as hexadecimal characters.

See the dCode pages for each hash function to know how it works in detail: MD5, SHA1, SHA256, etc.
How to decrypt a hash?
The principle of hashing is not to be reversible, there is no decryption algorithm, that's why it is used for storing passwords: it is stored encrypted and not unhashable.
Example:123+456=579, from 579 how to find 123 and 456? This is not possible except by trying all possible combinations.
The hash functions apply millions of non-reversible operations so that the input data can not be retrieved.
Hash functions are created to not be decrypable, their algorithms are public. The only way to decrypt a hash is to know the input data.
What are rainbow tables?
Theoretically, a brute-force mode is possible by testing all the binary strings, but a short message of 6 bytes already represents 281,000 billion combinations. Even with fast processors capable of performing millions of hash calculations per second, several days, months or years of calculations are therefore necessary to try all the possibilities in order to find a single hash.

However, users generally always use the same passwords and some characters more than others, so it is possible to store the most likely binary strings and their respective hashes in a very large dictionary. These dictionaries are called rainbow tables. These tables make it possible to test all the words of a given dictionary to check if their fingerprint corresponds to a given one.
Example: dCode uses its word and password databases with millions of pre-calculated hashes.
If the word is not in the dictionary, then there will be no result.
How to recognize a hash?
A hash can take many forms, but the most common are hexadecimal strings: 32 characters 0123456789abcdef for the MD5, 40 for the SHA-1, 64 for the SHA-256, etc.
The encoding system based on bcrypt uses the symbol $ followed by a number indicating the algorithm used and its possible parameters.
What is a salt (for a hash)?
The rainbow tables (gigantic databases of hash and password matches) are growing day by day and accumulating passwords stolen from various sites, and taking advantage of the computational performance of super calculators, allow today to decipher short passwords in minutes / hours.
In order to counter this technique, it is recommended to add salt (some characters in prefix or suffix) to the password/message. In this way, the precalculated tables must again be calculated to account for the salt that systematically modifies all the fingerprints, the salting step. Passwords are salted.
Example:MD5(dCode) = e9837d47b610ee29399831f917791a44 and MD5 (dCodeSUFFIX) = 523e9a80afc1d2766c3e3d8f132d4991
What is a cost (for a hash)?
Cost is the measure of the resources needed to calculate a hash. In order to complicate the task of creating the rainbow tables, it is possible to complicate some hashes so that the calculations take several milliseconds or seconds, which makes the duration necessary for the attacks too great to be applicable.
What is bcrypt?
bcrypt is a library of cryptographic functions that applies recursion rules to hash functions. Natively, the notions of salt and cost are applicable.

About Md5 :
Ntlm Hash Decrypter
Md5 (Message Digest 5
) is a cryptographic function that allows you to make a 128-bits (32 caracters) 'hash' from any string taken as input, no matter the length (up to 2^64 bits). This function is irreversible, you can't obtain the plaintext only from the hash. The only way to decrypt your hash is to compare it with a database using our online decrypter. Here we have a 10.000.000.000+ md5 hash database to help you with decryption. One should know that md5, although it's very used and common, shouldn't be use to encrypt critical data, since it's not secure anymore (collisions were found, and decrypt is becoming more and more easy). If you are building a new website, Sha-256, 512, or other kinds of encryption (with salt) would be better than md5, or even sha-1. Our decrypter database is coming from all the wordlist I was able to find on the internet. I then sorted them, and enlarge the final wordlist by creating a script that multiplicated the list to finally lend to a unique and pertinent wordlist.Md5 is no longer considered as a secure way to store passwords. In 2004, chinese scientists found a complete collision on md5. Since that date, collisions became easier and easier due to the increasing calculation power. It is now possible to find a md5 collision in a few minutes. If you are interested into md5 collisions and want to know more, you can check this link. It is now better to use hash functions such as Sha256, 512, bcrypt, scrypt, whirlpool for instance.
If you still want to use md5 to store passwords on your website, good thing would be to use a 'salt' to make the hash more difficult to crack via bruteforce and rainbow tables. A salt is simply a caracters string that you add to an user password to make it less breakable. For instance, say we are using the password 'password' (good idea). It will be obviously really easy to break. Then before storing this password in your database, you just concatenate a random string (generated with a php function for instance) such as a~/!c^12/*bn@( for example. That would make the password look like a~/!c^12/*bn@(password, which is obviously really harder to crack. Please note that it is preferable to use random generated strings as salt, if you just use the same string for each password it will be far too easy to break. You could also be creative and split the salt in two, then add a part at the beginning of the password and the other part at the end. Or for instance hash the salt before you concatenate it, everything is good to complexify your password before storing it.

By the way, if you're looking for a good way to remember very hard-to-break passwords, as a user, you could use sentences instead of a word. For instance illrememberthispasswordthatsforsure, will be really hard to break through bruteforce and rainbow tables. And that'll be even harder if you add uppercase and some numbers such as Hiimjohnandiwasbornin1980 for instance. It's easy to remember and hard to crack.
