SHA-1 is a cryptographic hash function which encrypts strings. It uses a digest size of 160 bits. SHA stands for Secure Hash Algorithm. This tool encrypts the string entered into using the SHA-1 Algorithm. HashKiller.co.uk allows you to input an MD5 hash and search for its decrypted state in our database, basically, it's a MD5 cracker / decryption tool. How many decryptions are in your database? We have a total of just over 829.726 billion unique decrypted MD5 hashes since August 2007.

Hash Decoder
Hash Calculator
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
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.
Example: dCode has for hashMD5e9837d47b610ee29399831f917791a44
Example: dCode has for hashSHA115fc6eed5ed024bfb86c4130f998dde437f528ee
Example: dCode has for hashSHA256254cd63ece8595b5c503783d596803f1552e0733d02fe4080b217eadb17711dd
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 decryptable.
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, by testing all input bit strings (all passwords for example), it is possible to store all the results in a dictionary. dCode uses its word and passwords databases already pre-calculated hash. These dictionaries are called rainbow tables.
It is therefore possible to test all the possible words in a dictionary to check if their fingerprint is the one sought.
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.

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.
