Hash Generator
Generate SHA-1, SHA-256, and SHA-512 hashes instantly in your browser.
🔒 All hashing happens in your browser. No data is sent anywhere.
How the Hash Generator Works
Type or paste any text into the input field. The tool automatically computes SHA-1, SHA-256, and SHA-512 hashes simultaneously using the Web Crypto API built into your browser. No server requests are made — everything runs locally.
Each hash is displayed in hexadecimal format. Click the Copy button next to any hash to copy it to your clipboard. SHA-256 is the most widely used algorithm for checksums and data integrity verification.
Frequently Asked Questions
What is a hash function?
A hash function takes any input and produces a fixed-length string of characters. The same input always produces the same output, but even a tiny change in the input produces a completely different hash. This makes hashes useful for verifying data integrity.
What is the difference between SHA-1, SHA-256, and SHA-512?
SHA-1 produces a 160-bit (40 character hex) hash and is considered weak for security-critical uses. SHA-256 produces a 256-bit (64 character hex) hash and is widely used for checksums and certificates. SHA-512 produces a 512-bit (128 character hex) hash offering the highest security.
Can I use this to store passwords?
No. SHA algorithms are fast by design, which makes them unsuitable for password storage. For passwords, use dedicated algorithms like bcrypt, scrypt, or Argon2 that are intentionally slow and resistant to brute-force attacks.
Is my text sent anywhere?
No. All hashing is performed locally in your browser using the Web Crypto API. Your text never leaves your device.
