Darknetzz/php-rand v1.3.0 on GitHub

[v1.3.0] (2026-04-03)

Major Features

Navbar and IA updates – Navigation structure now reflects the Math grouping better, labels were clarified (Convert -> Text & Data), and active-link handling was refactored so current tool context is highlighted more reliably.
Logo Generator upgrade – gen_image received a substantial UI/UX refresh with improved layout, richer interactions, and live preview-focused iteration.
Crypto compatibility hardening – Added RSA signing/verification padding fallback and broader algorithm compatibility updates (including Ed25519/Ed448 handling paths).
Shared output actions – copyableOutput and related rendering paths now support optional HTML actions and more consistent action/button styling across tools.
Tool card intros – Top-of-card guidance was tightened and aligned across many modules (encoding, crypto, JWT, networking, ShellCheck, SSH, and others) so descriptions and alert-style blocks are shorter, more consistent, and easier to scan.
Runtime/deployment refresh – Docker image/runtime config updated for PHP 8.5 + openssh-client; release workflow/docs (README, workflow, config, ignore rules) were refined to reduce release friction.
Networking IP backend – Centralized handle_ip flows for DNS forward/reverse lookup, IPv4 CIDR ↔ range conversion, and subnet math; subnet inputs accept dotted masks or /prefix via handle_ip_normalize_subnet_mask(); results render through shared handle_ip_kv_table() for consistent key/value output.
Crontab Explorer – New Misc tool to validate cron expressions (including macros like @daily and Vixie @reboot as a one-shot at daemon start), human-readable summaries, field breakdown, and timezone-aware previous/next run listings powered by dragonmantank/cron-expression. The full analysis runs automatically on debounced edits (expression, timezone, run count, reference time, include-current); Analyze Schedule remains as an explicit action. More options collapses advanced fields; schedule summaries use a dedicated human-readable block, */1 step fields are described like wildcards in the time summary for clearer copy, and the results layout was refined.
ShellCheck – New Misc tool to lint pasted shell scripts via the host shellcheck binary when available; JSON-backed diagnostics with severity, excerpts, and wiki links. Temp-file linting only (no persistence). Carriage returns are stripped from pasted scripts before linting to avoid spurious CRLF-related SC1017 warnings.
Form-aware random data – randomDataGetCompatibleFormBundle() extends generateRandomData() so random fills line up with more tool-specific forms (JWT, keypair sign/verify, SSH verification, CIDR/networking, and others) and handle <select> elements reliably.
Random shuffle samples – Crontab and ShellCheck random-data buttons use larger scenario pools, avoid picking the same scenario twice in a row, and keep related fields in sync (cron + timezone; script + filename + shell dialect).

📋 Detailed Changes (click to expand)

Navigation and Module Organization

Active state behavior - Refactored navbar link state handling so current modules are marked more consistently during navigation.
Math grouping - Updated navbar/module structure to better align math-related entries (including currency/units context) with dashboard category mapping updates.
Naming clarity - Updated wording in index.php and navbar labels to better describe available tool groups.

Logo Generator

UI redesign - Reworked modules/gen_image.php with improved structure, styling, and interaction flow.
Live feedback - Enhanced generation flow to better support iterative logo design with preview-oriented controls.

Cryptography

RSA compatibility - Added OpenSSL padding fallback in signing/verification paths to improve compatibility across environments.
Algorithm handling - Improved support logic for modern key algorithms including Ed25519/Ed448 handling paths.

Shared UX Utilities

Reusable actions - Extended shared output helpers to accept optional HTML actions, reducing per-module divergence and improving DRY reuse.
Action styling - Standardized button/link styles around copy/download and related output actions.

Tool card intros

Consistency pass - Reworked introductory/description blocks at the top of many modules/*.php files (BinHex, Brainfuck, Browser, Crontab, crypto and PEM tools, datetime, JWT, networking, ShellCheck, SSH, units, and more) for uniform structure and brevity.

Infrastructure and Docs

Docker runtime - Updated Dockerfile and image config for PHP 8.5, removed unused OPcache install steps, and added openssh-client.
Release process docs - Expanded release workflow guidance and environment toggle documentation in README and workflow-related files.
Repo hygiene - Updated ignore rules for local release tooling artifacts.

Networking

Backend - handle_ip(), handle_ip_normalize_subnet_mask(), and handle_ip_kv_table() in includes/handlers_functional.php for DNS lookup, IPv4 CIDR↔range conversion, and subnet calculations aligned with modules/networking.php.

Crontab Explorer

UI - modules/crontab.php under Misc; navbar entries in includes/navbar.php.
Backend - handle_crontab() in includes/handlers_functional.php; shared cron_evaluate_schedule(), humanization helpers, and CLI helpers in includes/tooling_helpers.php (loaded from includes/_includes.php).
Dependency - composer require dragonmantank/cron-expression for parsing and next/previous run calculation.
@reboot - Handled explicitly (not expressible as five cron fields); dedicated summary and “no periodic next runs” messaging instead of a parser error.
Live analysis - initCrontabLiveAnalyzeUi() in js/rand.js POSTs the same payload as Analyze Schedule into the main results panel with debouncing and out-of-order response guarding; removed the separate crontab_preview action.
Human summary - crontab_human_summary_block() presents schedule summaries in a dedicated styled block for clearer hierarchy.
Form UX - “More options” <details> hides secondary fields; shared native <details> styling in style.css; timezone is honored in random-data payloads and live analysis.
Time summary - cron_time_summary() treats */1 step fields like * for more natural wording; follow-up layout tweaks to the main results container in modules/crontab.php.

ShellCheck

UI - modules/shellcheck.php under Misc (script textarea, optional filename, dialect, minimum severity).
Backend - handle_shellcheck() runs shellcheck --format=json1 via proc_open (cli_run_command() / cli_find_binary() in includes/tooling_helpers.php); structured HTML cards per finding.
Input - handle_shellcheck() strips \r from script input before linting to reduce CRLF-driven SC1017 noise.
Random samples - Expanded shellcheckScenarios in js/rand.js with randomPickAvoidRepeat(); shuffle clears the per-form bundle and syncs script, filename, and dialect from the chosen scenario.

Random data

js/rand.js - randomDataGetCompatibleFormBundle() and generateRandomData() updates for context-specific bundles (JWT, keypair sign/verify, SSH verification, CIDR/networking, etc.), improved handling of <select> elements, and crontab timezone included when shuffling cron scenarios.
