How to Use the Hash Generator

Enter Text

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

Choose Algorithm

Select SHA-1, SHA-256, SHA-384 or SHA-512 based on your needs.

Generate

Click "Generate Hash" and the hash value appears instantly. Copy with one click.

Privacy

All computation happens in your browser — your text is never sent to any server.

What is a Hash Function?

A hash function is a mathematical algorithm that converts any text or file into a fixed-length string called a hash or digital fingerprint. Hash functions are used to verify file integrity, store passwords securely, and sign digital documents. SHA-256 is the most widely used algorithm in security applications today.

SHA functions produce values that cannot be reversed — it is computationally infeasible to recover the original text from a hash. Note that SHA-1 is no longer considered secure for sensitive applications; use SHA-256 or higher. The tool runs entirely in your browser via Web Crypto API, ensuring complete privacy.

Hash Generator FAQ

What is the difference between SHA-256 and SHA-512?

SHA-256 produces a 64-character hash while SHA-512 produces 128 characters. SHA-512 is theoretically stronger, but SHA-256 is sufficient for most use cases.

Can I reverse a hash to get the original text?

No. Hash functions are one-way — it is mathematically infeasible to recover the original input from a hash.

Why does the same text always produce the same hash?

This is a deterministic property of hash functions — the same input always produces the same output regardless of when or where it is computed.

Is MD5 better than SHA-256?

No. MD5 has been cryptographically broken for years. Always use SHA-256 or higher for security-sensitive applications.

Can I use hashing to verify file integrity?

Yes. This is one of the most common uses of hashing. Compare the hash of a downloaded file with the hash published by the source to verify it has not been tampered with.
