Understanding Cryptographic Hashes

A cryptographic hash function is a mathematical algorithm that maps data of arbitrary size to a bit string of a fixed size (the hash). It's like a digital fingerprint for your data.

Common Algorithms

Different algorithms offer different levels of speed and security.

MD5

Fast and widely used for checksums, but no longer considered secure against intentional tampering (collisions).

SHA-256

Part of the SHA-2 family. Highly secure and widely used in modern security protocols like SSL/TLS and Bitcoin.

Why Use Hashes?

  • File Integrity: Verifying that a downloaded file hasn't been corrupted or altered.
  • Password Storage: Storing the hash of a password instead of the password itself, so it can't be stolen.
  • Digital Signatures: Ensuring that a message or document comes from a trusted source.
