🔐 Hash Algorithm Information
SHA-1 (160-bit)
Legacy algorithm, deprecated for cryptographic use but still used for some applications.
SHA-256 (256-bit)
Most commonly used, provides excellent security for most applications.
SHA-384 (384-bit)
Provides higher security than SHA-256, good for sensitive applications.
SHA-512 (512-bit)
Highest security level, excellent for cryptographic applications requiring maximum security.
💡 Hash Usage Tips
- File Integrity: Compare hashes to verify file integrity after transfer
- Password Storage: Never store plain passwords - use salted hashes
- Digital Signatures: SHA-256 or higher recommended for signatures
- Blockchain: Bitcoin uses SHA-256 for proof-of-work
- Checksums: Use hashes to detect data corruption
- Unique IDs: Hash content to generate deterministic unique identifiers
