About the Hash Generator Tool
Generate cryptographic hash values using all available algorithms from the crypto-js library. Perfect for data integrity verification, password hashing, file checksums, digital signatures, and security applications.
Features:
- 12 hash algorithms including MD5, SHA-1, SHA-2 family (224/256/384/512), SHA-3 family (224/256/384/512), and RIPEMD-160
- Real-time hash generation as you type
- Support for text input with UTF-8 encoding
- Copy individual or all hashes to clipboard
- Uppercase and lowercase output options
- Hash length and bit size display for each algorithm
Hash Algorithm Categories:
- MD5: 128-bit hash - Fast but cryptographically broken, not secure
- SHA-1: 160-bit hash - Deprecated for security applications
- SHA-2 Family: SHA-224, SHA-256, SHA-384, SHA-512 - Industry standard, secure
- SHA-3 Family: Latest NIST standard, highly secure alternatives
- RIPEMD-160: 160-bit hash used in Bitcoin addresses
- HMAC: Hash-based Message Authentication Code for integrity and authenticity
Security Recommendations:
MD5 and SHA-1 are considered cryptographically broken and should not be used for security-critical applications. For password hashing, use PBKDF2, bcrypt, or Argon2. For general cryptographic hashing, use SHA-256 or higher from the SHA-2 or SHA-3 families.
What are Hash Functions?
Hash functions are mathematical algorithms that convert input data of any size into a fixed-size string of characters. They are one-way functions - you cannot reverse a hash to get the original input. Even a tiny change in input produces a completely different hash, making them ideal for detecting data changes and verifying integrity.
