Hash Generator – MD5, SHA-256, SHA-512
Generate MD5, SHA-1, SHA-256, and SHA-512 hashes from text or files. Verify file integrity and create secure checksums.
Our Hash Generator creates cryptographic hash values (SHA-256, SHA-1, and MD5) from any text input. Hashes are one-way functions that produce a fixed-length fingerprint of your data—identical input always yields identical output, while even a tiny change produces a completely different hash.
Hashes are essential for password verification, file integrity checks, digital signatures, and API authentication. Our tool uses the Web Crypto API and pure JavaScript implementations to compute hashes entirely in your browser. Your text is never sent to any server—processing happens locally for complete privacy.
Features
- SHA-256, SHA-1, MD5
- Instant hashing
- One-click copy
- 100% client-side

How to Use
Enter or paste the text you want to hash into the input area. Any length of text is supported.
Click the 'Generate Hash' button to compute SHA-256, SHA-1, and MD5 hashes simultaneously.
Copy any hash value using the copy button next to it. All three algorithms are computed in one operation.
Use the hashes for password verification, checksum validation, or any cryptographic purpose.
Frequently Asked Questions
What is the difference between SHA-256, SHA-1, and MD5?
SHA-256 is the most secure (256-bit output), recommended for passwords and security. SHA-1 is 160-bit and considered weak for security. MD5 is 128-bit and mainly used for checksums, not security.
Can I reverse a hash to get the original text?
No. Hash functions are one-way. Given a hash, you cannot mathematically recover the original input. This is why hashes are used for password storage—you verify by hashing the entered password and comparing hashes.
Is my text sent to a server?
No. All hashing is done entirely in your browser using client-side JavaScript and the Web Crypto API. Your text never leaves your device.
