What Is a Hash Generator?

A hash generator converts text or file data into a fixed-length hash value. The same input produces the same hash, and a small change produces a very different result. Hashes are one-way values and are not encryption.

How to Generate a Hash

Enter text or select a file.
Choose one or more hash algorithms.
Click Generate Hashes.
Copy or download the generated hash.

Common Hash Algorithms

MD5 is a fast legacy checksum algorithm and is not suitable for security. SHA-1 is a legacy algorithm that should be avoided for new security-sensitive systems. SHA-256 is widely used and recommended for integrity checks. SHA-384 and SHA-512 are longer SHA-2 variants with stronger output sizes.

What Are Hashes Used For?

Checking file integrity
Verifying downloads
Comparing data
Generating checksums
Storing passwords securely only through an appropriate password-hashing system such as Argon2, bcrypt, or scrypt
Validating software releases

Hashing vs Encryption

Hashing is designed to be one-way. Encryption is designed to be reversible with the correct key.

Is This Hash Generator Private?

All text and files are processed locally in your browser. No input is uploaded by the tool. Users should still avoid entering sensitive secrets into websites they do not trust.

FAQ

Is this hash generator free?

Yes. The tool is free and runs directly in your browser.

Is my text uploaded to a server?

No. Text and files are processed locally in your browser by this tool.

What is the difference between MD5 and SHA-256?

MD5 is an older algorithm with known cryptographic weaknesses. SHA-256 is a modern SHA-2 algorithm and is generally preferred for integrity and security-related use cases.

Can I reverse a hash?

A cryptographic hash is designed to be one-way. You generally cannot convert a hash back into the original input.

Why does changing one character create a completely different hash?

Cryptographic hash functions are designed so that even a small input change produces a drastically different output.

Which hash algorithm should I use?

For general file integrity checks, SHA-256 is usually a good default. The correct choice depends on the system and use case.

Can I generate a hash from a file?

Yes. Select the File tab, choose a file, select an algorithm, and generate the hash locally in your browser.

Does a matching hash prove that a file is safe?

No. A matching hash only confirms that the compared data is identical. It does not prove that the file is safe or trustworthy.
