Chinese Idiom Passphrase Generator
Selects 2–8 Chinese idioms from a small built-in list of 10 using browser cryptographic randomness. This is not a broad audited idiom corpus.
About this chinese idiom passphrase generator
Selects 2–8 Chinese idioms from a small built-in list of 10 using browser cryptographic randomness. This is not a broad audited idiom corpus Runs entirely in-memory using Web Crypto primitives to keep sensitive tokens, certificates, and cryptographic keys secure from third-party interception.
Encoding & cryptographic principles
Decodes, inspects, and validates authentication tokens and cryptographic credentials conforming to RFC 7519 (JSON Web Token - JWT), RFC 7515 (JSON Web Signature - JWS), and RFC 6238 (TOTP: Time-Based One-Time Password Algorithm). Decodes Base64URL-encoded JWT headers and claims payloads into syntax-highlighted JSON, parsing UNIX timestamps (iat, exp, nbf) into human-readable UTC dates and evaluating token expiration status without exposing private signing keys.
Worked verification 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:
Security parameters & input constraints
The count defaults to 3, is truncated to a whole number, and is clamped to 2–8; entries are drawn independently, so duplicates can appear. The bundled list has only ten idioms and the entropy estimate assumes uniform independent draws; this is not a high-value secret generator. A secure context with crypto.getRandomValues is required.
Cryptographic digests, encoded strings, and signatures generated by Chinese Idiom Passphrase Generator should be verified against target authentication systems before production use.
Client-side Web Crypto boundary
Key derivation, hashing, and encoding in Chinese Idiom Passphrase Generator execute in local memory using Web Crypto APIs without remote socket transmission.
Cryptographic specifications & RFC standards

How to use it
- Enter JSON with an optional count and separator, or use {} for the defaults.
- Run locally to draw idioms from the bundled ten-item list with browser secure random values.
- Read or copy the JSON passphrase, selected words, actual count, list size, entropy estimate, and warning.
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 example can I run locally?+
With {"count":3,"separator":"-"}, expect three selected idioms joined by a hyphen, wordCount 3, wordlistSize 10, and estimatedRandomBits 10. The selected idioms vary by 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.
