What is a Hash?
A hash function converts any input (text, file, data) into a fixed-size string of characters. The same input always produces the same hash, but even a tiny change completely transforms the output.
Common Uses:
Data Integrity: Verify files haven't been corrupted or modified
Password Storage: Store password hashes instead of plain text
Digital Signatures: Create unique fingerprints for documents
Checksums: Verify downloads are complete and authentic
Blockchain: Block hashes and transaction IDs
Algorithm Comparison:
MD5: 128-bit, fast but not collision-resistant. Good for checksums, not security.
SHA-1: 160-bit, deprecated for security use. Still used in Git.
SHA-256: 256-bit, recommended for security applications. Used in Bitcoin.
SHA-512: 512-bit, most secure option for cryptographic purposes.
