About Cryptographic Hashes
A cryptographic hash function converts data into a fixed-size string of bytes. The output, called a hash, is unique to the input data. Even a small change to the input produces a completely different hash.
Common Use Cases
- File Integrity: Verify downloaded files haven't been tampered with
- Password Storage: Store password hashes instead of plaintext
- Data Deduplication: Identify duplicate files or content
- Digital Signatures: Create unique identifiers for documents
- Blockchain: Core technology in cryptocurrencies
Security Notes
- MD5: Considered cryptographically broken. Use only for checksums, not security.
- SHA-1: Deprecated for security purposes. Avoid for new applications.
- SHA-256: Currently secure and widely used. Recommended for most applications.
- SHA-512: More secure than SHA-256, but slower. Use for high-security needs.
