What is a cryptographic hash?

A hash function takes an input (or 'message') and returns a fixed-size string of bytes. Even a tiny change in the input produces a drastically different hash.

Can a hash be decrypted?

No. Hashing is a one-way mathematical function. You cannot "decrypt" a hash back into the original text, you can only try to crack it via brute-force or rainbow tables.

Why use SHA-256 over MD5?

MD5 is considered cryptographically broken and vulnerable to collision attacks. SHA-256 is the modern standard used in blockchain, SSL, and secure password hashing.

Hash Generator

Generate MD5 and SHA256 cryptographic hashes for your text strings instantly.

What is the Hash Generator?

The Hash Generator instantly calculates cryptographic hash functions (MD5 and SHA-256) for any input string. Hashes are irreversible unique digital fingerprints of data.

How to use it
