Use these groups to find a task guide. Each count matches the tools listed in that group. A tool can appear in more than one group.
- Structured DataA syntax check does not verify field meanings. Check CSV headers, quoted cells, and identifier types before converting records.7 tools
- Encoding & Number BasesDistinguish encoded bytes from an integer written in another base. Check the source alphabet, padding, and delimiters first.11 tools
- Cryptography & CiphersMatch the sender's cipher, key, mode, and IV. Keep classical puzzle ciphers separate from tools for protecting new messages.15 tools
- Hashing & ChecksumsChoose bcrypt for password hashes or SHA-2 for digests. For protocol checksums, match the exact CRC, Adler, or Fletcher variant.3 tools
- Keys, Certificates & TokensA key, certificate, and signing request use different containers. Identify the container before converting its bytes or inspecting its fields.10 tools
- Network & WebDistinguish URL substitutions from protocol fields. Defanging changes link text; NetBIOS and VarInt tools require their own byte formats.5 tools
- Numbers, Units & CalculatorsMatch the question to statistics, sets, algebra, binary arithmetic, science, or ramp geometry. Units and model assumptions change the answer.10 tools
- Extraction & AnalysisExtract addresses with a protocol, or hexadecimal strings of a chosen length. A match does not prove safety or identity.3 tools
