- Client-Side Processing: All hashing happens in your browser for maximum privacy
What Are Cryptographic Hashes?
A cryptographic hash is a fixed-size string of characters generated from input data of any size. Hash functions are one-way operations, meaning you can't reverse a hash to get the original input. They're commonly used for verifying data integrity, storing passwords, and creating digital signatures.
Hash Algorithm Comparison
- MD5: 128-bit hash, fast but considered cryptographically broken. Use only for checksums, not security.
- SHA-1: 160-bit hash, faster than SHA-2 but deprecated for security applications.
- SHA-256: 256-bit hash, secure and widely used. Part of the SHA-2 family.
- SHA-384: 384-bit hash, more secure than SHA-256, part of SHA-2 family.
- SHA-512: 512-bit hash, strongest option in SHA-2 family, recommended for high-security needs.
Common Use Cases
- Verifying file integrity and detecting corruption
- Checking downloaded files match their published checksums
- Generating unique identifiers for data
- Comparing files without transferring entire contents
- Creating content fingerprints for deduplication
- Validating data hasn't been tampered with
Security Note
While MD5 and SHA-1 are included for compatibility and checksums, they should not be used for security-critical applications like password hashing or digital signatures. For security purposes, use SHA-256, SHA-384, or SHA-512. For password hashing specifically, use dedicated algorithms like bcrypt, Argon2, or PBKDF2.
Privacy & Security
All hash generation happens locally in your browser using the Web Crypto API and native JavaScript. Your text and files never leave your device, and no data is sent to any server. This ensures complete privacy and security for your sensitive data.
