Chinese Idiom Passphrase Generator
Chinese Idiom Passphrase Generator: Samples 4 four-character idioms from an authoritative idiom corpus using CSPRNG entropy.
About this chinese idiom passphrase generator
Chinese Idiom Passphrase Generator — browser-based utility.
How this tool works
Samples with replacement from a fixed bundled list of ten four-character idioms using the local secure random index helper. This is not Diceware or an authoritative large corpus, and the page warns against using the small list for high-value secrets.
- Token Structure Extraction: Splits JWT strings on '.' delimiters into Header, Payload, and Signature segments.
- Base64URL Decoding: Decodes URL-safe Base64 segments into raw JSON strings without executing unverified signature payloads.
- Claims Parsing & Timestamp Evaluation: Parses registered claims ('exp', 'nbf', 'iat', 'iss', 'aud') and checks current clock validity.
- Cryptographic Status Reporting: Displays token signature algorithm (RS256, HS256, ES256, EdDSA) and warns that client decoding does not verify cryptographic signatures without the public key.
Worked example
Scenario: Generate a three-word phrase from the documented bundled idiom list.
Sample input:
Processing: Clamp count to 2–8 and select with replacement from the fixed 10-item list using secure random indices.
Illustrative output:
Limits and verification
Rejects strings that do not contain exactly two '.' delimiters. Explicitly informs the user that client-side decoding inspects token claims but CANNOT verify mathematical signature validity unless the corresponding public key/secret is supplied.
Examples demonstrate an expected workflow; they do not prove every input or every branch of an external specification. Check important results with an independent source before using them for money, security, compliance, safety, or irreversible file changes.
Browser processing boundary
Tool input is processed by code running in the browser and is not intentionally sent to a CZOA processing API. The page can still request ordinary site assets, analytics, or advertising when those services are enabled. Browser extensions and managed-device software remain outside this tool's control.

Frequently asked questions
How are passphrases selected?+
The generator parses JSON count and separator, selects with replacement from its bundled list of ten four-character idioms using a secure random index, and returns the joined phrase plus the selected words.
Which controls and range are implemented?+
The primary field accepts JSON. count is truncated and clamped from 2 through 8; separator defaults to a hyphen. The output reports wordCount, wordlistSize and estimatedRandomBits.
What did the tested browser result establish?+
With {"count":3,"separator":"-"}, the frozen page returned three words, a 10-item list size, a hyphen-joined phrase, and estimatedRandomBits of 10. This verifies the displayed small-list calculation for that run.
Is this suitable for high-value secrets?+
No. The bundled list is deliberately small and the page itself warns about it. This is not Diceware, not a large audited corpus, and it does not assess storage, account recovery, or device compromise.
