Which hash algorithm should I use?

SHA-256 is recommended for most use cases. MD5 and SHA-1 are considered weak for security purposes.

Can I verify file integrity?

Yes. Generate a hash and compare it against a known checksum to verify file integrity.

Are hashes reversible?

No. Hash functions are one-way, so you cannot recover the original input from a hash.
