Hash Generator

Generate MD5, SHA1, SHA256 from any input text.

Input Text

MD5 Hash

SHA1 Hash

SHA256 Hash

Hash Usage Tips

Use SHA256 for most security-sensitive applications
MD5 is faster but less secure than SHA algorithms
Hashes are one-way functions and cannot be reversed
For password storage, use specialized algorithms like bcrypt

Common Hash Applications

File integrity verification
Digital signatures
Data deduplication
Blockchain technology

About Hash Functions

Hash functions are mathematical algorithms that convert data of any size into a fixed-size string of characters. They have several important properties:

They produce the same output for the same input every time
Even a small change in the input produces a completely different hash
It's computationally infeasible to find two different inputs that produce the same hash
It's practically impossible to reverse a hash to find the original input

This hash generator creates MD5, SHA1, and SHA256 hashes from your input text. All hash generation happens directly in your browser - no data is sent over the internet or stored on our servers.
