VOID vs SMIME Toolkit

With VOID, you can: • Encrypt your texts securely and offline. VOID uses AES-256 encryption to protect your information with military-grade security. All encryption and decryption happen locally on your device - your data never leaves your phone. No cloud storage, no internet connection, no third-party servers. Your information stays completely offline. • Encrypt your files with AES-256 + Argon2id. VOID protects not just text, but your files too. File encryption combines AES-256 with Argon2id - a memory-hard key derivation function that won the Password Hashing Competition - making brute-force attacks practically impossible. Encrypt any file directly on your device with no internet connection required. • Customize encryption parameters. Take full control of how your data is secured. Fine-tune settings including salt length (0-256 bytes), number of iterations (up to 500), memory usage (up to 1024 MiB), parallelism (up to 6 threads), and key length (up to 224 bytes). Apply up to 7 layers of encryption for maximum security. Advanced users can optimize encryption strength according to their needs. • Use a hidden key (VOID Secret). VOID Secret is a hidden key variant generated per device. Each device can generate up to 999 different hidden keys, providing an extra layer of protection. Only you can decrypt messages with the correct VOID Secret - your communication stays fully confidential even if the main password is shared. The hidden key is optional but adds meaningful security for sensitive conversations. • Encode your texts in emoji. Transform your messages into emoji sequences. VOID converts your text to Base64 and then into emojis, so you can send encrypted messages that look like strings of symbols. Adds a layer of secrecy while making encryption visually engaging. • Generate and customize QR codes. Turn any encrypted text into a QR code. Customize appearance - colors, style, and format - then export in multiple formats and share however you choose. Additional Features: Offline-first design: VOID never connects to the internet, stores, or transmits your data. No accounts or registration: No personal information is ever required. Temporary decryption timer: Set a self-expiring timer so messages can only be decrypted within a limited time. Security Mode: Blocks screenshots and screen recordings completely. Multilingual support: Use VOID in your preferred language. Intuitive UI/UX: Designed with Apple's guidelines in mind, with animations, haptic feedback, and simple navigation. With VOID, your information is encrypted and under your full control. You decide how, when, and with whom to share it. Secrets truly stay secret.

SMIME Toolkit: S/MIME Setup - Secure Email Certificates SMIME Toolkit guides you through S/MIME setup on iPhone and iPad in clear steps. Generate keys on-device, request certificates from your organization or SMIME Toolkit's backend, and export identities for manual installation in iOS Settings. Sign and encrypt email in Apple Mail while keeping your private keys under your control. WHAT THIS APP DOES SMIME Toolkit guides you through the full S/MIME enrollment process: - Generates cryptographic keys securely on your device (RSA-2048 default, optional ECC P-384) - Builds standards-compliant certificate signing requests (CSRs) - Requests signed certificates from your organization's secure backend - Exports PKCS#12 (.p12) identities for manual installation in iOS Settings - Optionally generates both RSA and ECC identities for compatibility targets The app never configures Mail automatically and never accesses your email content. KEY FEATURES - On-device key generation (Keychain-backed) - Standards-compliant CSR with email address (subjectAltName) - Secure HTTPS requests to your organization's issuer - PKCS#12 (.p12) export with a password you choose - Face ID / Touch ID for sensitive actions - Manual install flow (required by iOS) - CA certificate export and optional trust profile for easier setup - Optional ECC P-384 support and dual-identity export flow HOW IT WORKS - Enter your email address - Generate a key pair and CSR on your device - Request a certificate from your signing service - Export your identity (.p12) or trust profile - Install manually in Settings > Mail > Accounts > Advanced Once installed, enable S/MIME signing and encryption in Apple Mail. PRIVACY & SECURITY - Your private key never leaves your device - Only your CSR and email address are sent for certificate issuance - No access to Mail, messages, or accounts - No ads or tracking IMPORTANT NOTES - This app cannot configure Apple Mail automatically - Manual installation is required by iOS - Certificate issuance depends on your organization's backend - Private CAs must be trusted in Certificate Trust Settings FOR TEAMS & ENTERPRISES SMIME Toolkit is designed for organizations that want a simple, user-driven S/MIME enrollment flow: - Works with internal CAs and private trust roots - Predictable, auditable issuance workflows - Pluggable backend interface for partner CA integrations - Enterprise bulk generation supports RSA default, ECC opt-in, or both TROUBLESHOOTING - Ensure your network can reach the signing service - Certificate chain errors usually indicate issuer misconfiguration - If Mail doesn't show encryption, confirm CA trust and recipient certificates COMPATIBILITY - Works with Apple Mail on iOS after manual installation - Compatible with clients that support PKCS#12 identities once installed SMIME Toolkit is a certificate utility. It does not provide email hosting, account management, or message delivery. Apple Mail remains controlled by iOS settings and your email provider.
