SMIME Toolkit vs EncryptChat X

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.
