Hash Generator
Generate MD5, SHA-256, SHA-384, and SHA-512 hashes
Why Use This Tool?
- Generate MD5, SHA-256, SHA-384, and SHA-512 hashes from text or files instantly.
- Verify file integrity by comparing hash values -- useful for downloads and data transfers.
- All computation happens locally in your browser using the Web Crypto API.
How It Works
Hash functions produce a fixed-size digest from any input. SHA-256 generates a 256-bit (32-byte) digest represented as 64 hexadecimal characters. The function is one-way: you cannot reverse the hash to recover the original input.
How to Use
- Enter text or upload a file
- All hash values (MD5, SHA-256, SHA-384, SHA-512) are computed instantly
- Click copy next to any hash to copy it to clipboard
FAQ
What hash algorithms are supported?
This tool supports MD5, SHA-256, SHA-384, and SHA-512. SHA algorithms use the Web Crypto API for maximum performance, while MD5 is computed using a pure JavaScript implementation.
Can I hash files?
Yes. You can drag and drop a file or click the upload button. The file is read in your browser and hashed locally — it is never uploaded to any server.
Is MD5 still secure?
MD5 is considered cryptographically broken and should not be used for security purposes. It is still commonly used for checksums and data integrity verification.
Which hash algorithm should I use?
For security purposes, use SHA-256 or SHA-512. For simple file integrity checks where security is not a concern, MD5 is faster and widely supported.
Which hash algorithm should I use?
SHA-256 is recommended for most purposes. MD5 and SHA-1 are faster but considered insecure for cryptographic use. SHA-512 provides the highest security but is slower.
