• You can securely & easily exchange secrets, passwords or session keys with RSA public keys included in the certificates

RSA Key Exchange
• Transfer your bank account number securely
• Share access codes (e.g. PDF passwords, Cloud access passwords) securely
• Exchange a session key for AES Encryption

AES Encryption
• Encrypt your text messages securely and share them (AES recommended instead of RSA because of performance)
