Do I need an account?

No. Guests can hash text freely.

No. Hashing is one-way. Do not use it as a password vault.

Which algorithm should I pick?

Use SHA-256 for new checksums. Use SHA-1 only when a system still expects it.

Can I reverse a hash?

No. A hash is a fingerprint, not recoverable plaintext.
