      "description": "生成、校验与验证 OAuth2 / OIDC PKCE（RFC 7636）的 code_verifier 与 S256 code_challenge 配对。三种模式：(1) 从密码学安全随机字节（256/384/512/768 位熵）生成全新的 verifier + challenge；(2) 按 RFC 审计你已有的 verifier——长度（43–128）、字符集 [A-Za-z0-9-._~] 与 ≥256 位熵；(3) 通过重算 BASE64URL(SHA256(verifier)) 验证 verifier/challenge 配对。可选构建完整的授权请求 URL 与令牌交换体。补足通用的 nonce-generator（仅输出 verifier+challenge 配对）——增加 RFC 合规审计与配对验证。",
