Hash Generator
Generate and verify MD5, SHA-1, SHA-256, and SHA-512 hashes.
Generate Hash
Create a cryptographic hash from text or a file.
What are Cryptographic Hashes?
A cryptographic hash function takes input data and produces a fixed-size string of bytes. The output (hash) appears random and is unique to the input data. Even a tiny change in the input produces a completely different hash.
Supported Algorithms
- MD5: 128-bit hash. Fast but considered cryptographically broken. Use only for checksums, not security.
- SHA-1: 160-bit hash. Deprecated for security use but still common for integrity checks.
- SHA-256: 256-bit hash from the SHA-2 family. Recommended for most security applications.
- SHA-512: 512-bit hash from the SHA-2 family. More secure than SHA-256, slightly slower.
Common Use Cases
- Verifying file integrity after downloads
- Creating checksums for data verification
- Comparing files without sharing contents
- Password storage (with proper salting)
- Digital signatures and certificates
Security Note
All hashing is performed locally in your browser. Your data is never sent to any server. For file hashing, the entire file is processed in memory, so very large files may impact performance.
Features
Our Hash Generator tool makes it easy to create cryptographic hashes from text or files. Whether you need to verify file integrity, generate checksums, or create secure password hashes, this tool has you covered.
All hashing is performed locally in your browser using the Web Crypto API for SHA algorithms and a JavaScript implementation for MD5. Your data never leaves your device, ensuring complete privacy and security.
