Hash Generator— Free & Private
Generate SHA-1, SHA-256, SHA-384, and SHA-512 hashes from any text — entirely in your browser.
What Is a Hash Generator?
A hash generator converts any text or file input into a fixed-length cryptographic hash value using algorithms such as MD5, SHA-1, SHA-256, and SHA-512. Hashes are one-way functions widely used for verifying file integrity, storing passwords securely, and creating digital fingerprints of data. Our hash generator runs entirely in your browser, so your sensitive text and files are never transmitted to any server.
How to Use Hash Generator
Enter your text or upload a file
Type or paste the text you want to hash, or upload a file to compute its hash.
Select a hash algorithm
Choose from MD5, SHA-1, SHA-256, SHA-512, or other supported algorithms.
Copy the hash output
View the computed hash value and copy it to your clipboard with one click.

Frequently Asked Questions
What is the difference between MD5, SHA-1, and SHA-256?
MD5 produces a 128-bit hash and is fast but considered cryptographically weak. SHA-1 produces a 160-bit hash and is also deprecated for security use. SHA-256 produces a 256-bit hash and is currently considered secure for most applications including digital signatures and certificate validation.
Can I reverse a hash to get the original text?
No. Cryptographic hash functions are one-way operations by design. You cannot recover the original input from a hash value. This property is what makes them useful for password storage and data integrity verification.
Is my data safe when using this hash generator?
Yes. All hashing is performed locally in your browser using the Web Crypto API. Your text and files never leave your device and are not stored anywhere.
