What can you do with Crypto?
Encrypt your messages for WhatsApp, Facebook, Telegram and other messengers
Encrypt your texts to securely store or send them
Save your passwords as hash
Learning support with mathematical DH and RSA implementations
Mathematical functions also suitable as everyday helpers

Some special use cases for Secure Communication Tools:
RSA Certificates
Share your certificate to prove your identity
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)
