What is the Hash Generator?
The Hash Generator is an online developer tool that converts a text, password, file content or any other data input into a fixed-length digest value. This value is called a hash, digest or message digest.
Hash algorithms are one of the fundamental cryptographic building blocks used in data integrity checks, file comparison, cache key generation, unique identifier creation and password storage systems. When the same data is processed with the same algorithm, the same hash result is obtained.
Hashing is not encryption. It is not intended to reliably return from the hash value to the original text. Therefore, sensitive passwords should not be stored with plain SHA or MD5 alone; salts and slow key derivation algorithms should be used instead.
How to use the Hash Generator?
Follow the steps below to generate a hash value from your text.
Add the text
Type or paste the text you want to hash into the input field.
Select the algorithm
Choose one of the options MD5, SHA-1, SHA-256, SHA-384 or SHA-512.
Generate the hash
Click the Generate Hash button to view the hexadecimal result.
Use the result
Copy the hash value or download it as a text file.
Hash creation example
Aşağıdaki örnekte Tekno Danışman metni SHA-256 algoritmasıyla işlenir. Metindeki tek bir karakterin değişmesi bile tamamen farklı bir hash sonucu üretir.

The algorithms differ in output length, intended use and security level.
| Algorithm | Output length | Security status | Recommended use |
|---|---|---|---|
| MD5 | 128 bits / 32 hex characters | Weak for cryptographic use | Simple non-cryptographic integrity checks |
| SHA-1 | 160 bits / 40 hex characters | Not recommended for cryptographic use | Compatibility with legacy systems |
| SHA-256 | 256 bits / 64 hex characters | Modern and widely used | Data integrity, signatures and general-purpose hashing |
| SHA-384 | 384 bits / 96 hex characters | High security | Systems that require a longer digest |
| SHA-512 | 512 bits / 128 hex characters | High security | Strong data integrity and cryptographic operations |
Where are hash values used?
Hash functions are used for many different purposes in software development, security and data integrity processes.
File integrity
Used to check whether a downloaded or transferred file has been altered.
Digital signatures
Hash functions are used to produce a fixed-length digest of the data to be signed.
Cache keys
Consistent and short cache keys can be generated from large or complex inputs.
Data comparison
Helps check whether two pieces of data are identical without comparing their entire content.
Unique identifiers
Can be used to create content-based keys and change-detection values.
Password systems
Passwords should not be hashed directly; a salt and methods such as Argon2, scrypt or PBKDF2 should be used.
