Darknetzz/php-rand v1.2.9 on GitHub

Performance: faster initial page load - Reduced initial payload by lazy-loading tool modules, deferring non-critical scripts, and loading changelog content on demand.
On-demand frontend libraries - marked, highlight.js, and code-input are now loaded only when needed by active modules/features.
Production deployment guidance - Added server-side compression and cache-header recommendations for Nginx/Apache.
New cryptography modules - Added Private/Public Keys, SSH Key Generator, and CSR Generator under Cryptography.
OpenSSH public key export - SSH generator now emits true OpenSSH public key lines (RSA/ECDSA, Ed25519 when runtime details are available) in addition to PEM.
Hybrid key generation mode - Added client-side WebCrypto generation mode with server fallback for compatibility-sensitive flows.
New key utilities - Added PEM/OpenSSH Converter and Crypto Diagnostics modules for format conversion and runtime capability checks.
Logo generator rewrite - Replaced the old php-logogen dependency with a new built-in Logo Generator module in this repository.

📋 Detailed Changes (click to expand)

Module loading - Updated index.php to render only dashboard on first load; other modules now load on first navigation via new load_module.php.
Script loading - Added defer to non-critical script tags (jQuery, Tabler, Marked, Highlight.js, Code Input, Axios, and local scripts) to reduce render blocking.
Changelog modal - Removed eager inline CHANGELOG.md embedding from HTML and switched to AJAX fetch + parse when the modal is opened.

On-demand module fetch - Added loadModule() flow in js/rand.js and integrated it into navigate() so missing module sections are fetched and inserted dynamically.
UX safeguards - Added loading placeholders for lazy module fetches and improved error handling when a module fails to load.
AJAX submit fix for lazy modules - Switched to delegated form submit handling in js/rand.js so dynamically loaded tools no longer navigate to gen.php on submit.

Library lazy loading - Removed global marked/highlight.js/code-input includes from index.php; added reusable loadScriptOnce()/loadStyleOnce() helpers with one-time caching in js/rand.js.
Feature-gated assets - Markdown assets now load only for markdown/changelog rendering; code-input assets load only when code-input elements exist in a visible module.
Deployment docs - Added README.md guidance for gzip/brotli compression and cache headers for static assets vs dynamic HTML/PHP responses.

New modules - Added modules/keypair.php, modules/ssh_keygen.php, and modules/csr.php with matching navbar entries in includes/navbar.php.
Additional modules - Added modules/pem_openssh.php (public key converter) and modules/crypto_diagnostics.php (runtime checks).
Shared backend helpers - Added reusable keygen/export helpers in includes/handlers_functional.php for algorithm resolution, keypair generation, and download rendering.
OpenSSH output - Added server-side OpenSSH serialization in handle_ssh_keygen() for RSA/ECDSA public keys, with runtime-dependent Ed25519 support and graceful fallback warnings.
Hybrid client/server mode - Added browser-side key generation for keypair/SSH modules through js/rand.js (generation_mode: auto/client/server), with automatic fallback to server mode when WebCrypto support is missing or features require server processing.
Format conversion - Added handle_pem_openssh_convert() with PEM -> OpenSSH conversion and OpenSSH -> PEM conversion via host ssh-keygen when available.
Runtime diagnostics - Added handle_crypto_diagnostics() to verify algorithm availability and OpenSSH export support per algorithm.
Status visibility improvements - Updated SSH/diagnostics status rendering with clearer icon badges and better contrast for dark mode.

Submodule removal - Removed .gitmodules and dropped the php-logogen submodule path from this repository.
Logo generator rebuilt in-app - Replaced the old link-out approach with a native modules/gen_image.php UI backed by handle_logo_generate() in includes/handlers_functional.php.
Logo presets and polish - Added quick presets (App Icon, Banner, Initials Badge), palette randomization, and inline hints for faster iteration.
