Is a hash encryption?

No. Hashing is a one-way function: it produces a fixed-size fingerprint of the input, but the input cannot be recovered from the hash.

What is a hash used for?

Hashes are commonly used to verify file integrity (checksums), store passwords securely and detect duplicate data.
