What is a hash?

A hash function takes input data of any size and produces a fixed-length string of characters. The same input always produces the same hash, but even a tiny change in input produces a completely different output.

Common use cases

Hashes are used for password storage, data integrity verification, digital signatures, checksums for file downloads, and deduplication. SHA-256 is widely used in blockchain and TLS certificates.

Security notes

MD5 and SHA-1 are considered cryptographically broken and should not be used for security purposes. For password hashing use bcrypt or Argon2. For integrity checks SHA-256 or SHA-512 are recommended.
