How to Generate MD5, SHA-1, SHA-256, and SHA-512 Hashes
Create cryptographic hashes for any text right in your browser, without sending anything to a server.
Tool Used
Hash Generator
Open the Hash Generator
Go to /tools/security/hash-generator.
Type or paste your input
Enter the text you want to hash. This can be a password (for testing only), an API key, a file's contents, or any string. The tool processes everything locally in your browser so nothing is sent anywhere.
Pick a hash algorithm
Choose MD5 for legacy checksums (no longer safe for security). Choose SHA-1 for older systems that still require it. Choose SHA-256 for modern integrity checks and digital signatures. Choose SHA-512 for the longest output. SHA-256 is the standard choice for new code.
Read the resulting hash
The hash output is the same length every time for a given algorithm regardless of input size. MD5 returns 32 hex characters, SHA-1 returns 40, SHA-256 returns 64, and SHA-512 returns 128.
Copy and use it
Click Copy to use the hash for verification, file integrity checks, change detection, or storing alongside file uploads. Never use plain MD5 or SHA-1 to store user passwords in a real application. Use a dedicated password hashing function like bcrypt, scrypt, or argon2 instead.
All done!
You are ready to use Hash Generator like a pro.
