NULVEX vs Paste

NULVEX is described on its supplied site as AndroidIRCx, an IRCv3-compliant client for Android. It connects to multiple IRC networks and servers at the same time, with channels, private messaging, server failover, IRCv3 capability negotiation, and DCC transfers. Direct messages and channels are listed as end-to-end encrypted with key verification, while IRC server links can use SSL/TLS. SASL handles server login. SOCKS5, HTTP CONNECT, and Tor proxies can be configured per network or globally. The app includes JavaScript scripting with event hooks, custom commands, and timers; scripting time can come from rewarded ads or become unlimited through a Pro purchase. Other tools include Bouncer/ZNC integration, a services panel for NickServ, ChanServ, HostServ, and OperServ, voice messages, camera and video capture, and encrypted backup and restore. Android 7.0 is required, with Android 11 recommended. Downloads are available through Google Play or a direct APK. The project is open source under GPL-3.0, with offline access listed. Google Play instead describes NULVEX as an encrypted notes vault, creating a product-description mismatch.

Paste is a private notepad and clipboard for syncing text, links, and code snippets across macOS, Linux, and Windows. Notes may be plain text, Markdown, or code, and users can pin frequently used items. It works offline and merges changes automatically after devices reconnect. The site says local search can find items in under 30 ms across 10,000 entries. Pairing uses a QR scan, short code, or recovery phrase, and each device receives a revocable signing key. Paste says it encrypts content on the device with XChaCha20-Poly1305 before storage or syncing, deriving keys from the recovery phrase. Optional relays store encrypted blocks and can see network metadata, but cannot read note contents or keys. The encryption envelope, sync engine, relay client, and verifier are open source; Paste also includes a verifier and standalone CLI. Desktop versions run through the Pear runtime, which installers require. On Windows, the first launch fetches the app peer-to-peer and may take about one minute. iOS and Android are in development. Paste is free and requires no account; it does not provide anonymity or provable physical deletion of ciphertext retained on third-party disks.
