About Hashing
Hashing is a one-way mathematical function that turns an input of any length into a fixed-size string of characters. It is commonly used for checksums, password storage, and data integrity verification.
- MD5: Widely used but considered cryptographically broken. Good for non-security checksums.
- SHA-1: No longer recommended for security. Replaced by SHA-2.
- SHA-256: Standard for SSL/TLS and many blockchain applications. High security.
- SHA-512: Extremely secure, recommended for sensitive data hashing.
What is a Hash Generator?
A Hash Generator is a tool that takes an input string and converts it into a fixed-length alphanumeric output using a specific algorithm. This "digital fingerprint" is unique to the input data—if even a single character in the input changes, the resulting hash will be completely different.
Why use local hashing?
Most online tools send your data to their servers to be processed. At CuscusLab, we use the Web Crypto API to perform all hashing directly on your device. Your sensitive text or passwords never leave your browser, making it a 100% secure way to generate checksums and verify data integrity.
Common Use Cases
Data Integrity
Verify that downloaded files haven't been corrupted or altered by comparing MD5 or SHA-256 checksums.
Password Storage
Developers use hashes (like SHA-512) for basic checks, but for production security, we recommend using ourBcrypt Generator which is designed for password hashing.
Digital Signatures
Hashing is a core component of blockchain and signature algorithms, ensuring authentication.
