RAR formatsRAR3 vs RAR4 vs RAR5 Encryption
RAR generations changed both encryption and archive behaviour over time. Identify the generation first, then account for headers, solid compression, split volumes and password clues before estimating the work.
Generation is a recovery input
RAR3 and RAR4 belong to the older family, while RAR5 introduced a newer AES-256-based design and optional header encryption. A utility may show these as version details even when the extension is simply .rar.
The generation does not predict a result by itself. Candidate quality, password length, archive health and whether a complete volume set is available can dominate the practical outcome.

Volume set and integrity
Encryption is only one layer
A solid archive can make a damaged early block affect later entries. Split volumes require all parts. Encrypted headers hide the file list. These structural details explain failures that look like password errors.
Record the utility name, version, exact error, visible filenames and volume names. That context is more actionable than a generic claim that RAR5 is 'hard'.
A useful comparison avoids fake precision
Published benchmark numbers vary by GPU, implementation, verification mode and archive. Use them as directional evidence only. A responsible estimate should rest on your candidate plan and a short sample test, not a fixed success percentage.
Do not confuse a benchmark with a guarantee
Measured candidate rates can change across tools and hardware. They do not predict whether your password is in the tested candidates.
