Hash Generator (MD5 & SHA-256)

Generate MD5 and SHA-256 hashes from any text input. Compare hashes, verify data integrity, and more.

Your data never leaves your browser

How to Use

  1. 1

    Enter your text

    Type or paste the text you want to hash in the input field.

  2. 2

    Click Transform

    The tool computes the MD5 hash of your input. The hash is generated entirely in your browser.

  3. 3

    Copy the hash

    Use the Copy button to copy the resulting hash string.

What is Hash Generator?

A cryptographic hash function takes an input of any size and produces a fixed-size output (the hash or digest) that uniquely represents the input data. Even a tiny change in the input produces a completely different hash.

MD5 produces a 128-bit (32-character hex) hash. While no longer considered secure for cryptographic purposes due to collision vulnerabilities, MD5 is still widely used for checksums, file integrity verification, and non-security-critical applications.

SHA-256 (part of the SHA-2 family) produces a 256-bit (64-character hex) hash and is considered cryptographically secure. It is used in SSL/TLS certificates, Bitcoin mining, digital signatures, and password storage systems.

FAQ

Is MD5 still safe to use?
MD5 should not be used for security-critical applications like password hashing or digital signatures due to known collision attacks. However, it is still useful for checksums, cache keys, and data integrity checks where security is not a concern.
What is the difference between MD5 and SHA-256?
MD5 produces a 128-bit hash (32 hex characters) and is faster but vulnerable to collisions. SHA-256 produces a 256-bit hash (64 hex characters) and is currently considered cryptographically secure.
Can I reverse a hash to get the original text?
No. Hash functions are one-way — you cannot mathematically reverse a hash to recover the original input. However, common inputs can be looked up in rainbow tables, which is why salting is used in password storage.
