What is hashing?

Hashing converts input data into a fixed-size string using a mathematical function. It is one-way — you cannot reverse a hash to get the original input.

When do you need it?

Password storage, file integrity checks, data fingerprinting, blockchain, and digital signatures.

How to use

1) Paste your text into the input box.
2) Select the hash algorithm (MD5, SHA-1, SHA-256, SHA-512).
3) Copy the generated hash.

FAQs

What is a hash?

A hash is a fixed-size string generated from input data. The same input always produces the same hash.

What algorithms are supported?

MD5 (128-bit), SHA-1 (160-bit), SHA-256 (256-bit), and SHA-512 (512-bit).

What is MD5 used for?

Checksums, file integrity checks, and fingerprinting. Not secure for cryptographic use.

What is SHA-256 used for?

Password hashing, digital signatures, blockchain, and security-critical applications.

Does it store my data?

No. All hashing happens locally in your browser. Your data is never uploaded or stored.
