I would appreciate this as well. What I was thinking is a way to send public encryption key to a group, and everything sent to that user comes encrypted and in Base64 or something, and decrypted at the receiving end with a private key such as openssl can encrypt/decrypt. Anything sent unencrypted would show red highlighting, and any user using a telegram client that doesn't have the feature will see scrambled base64 content.
