They’re just banning accounts, not even access in a lot of cases, and jeebus other technologies exist. IRC and XMPP aren’t going away ever
Maybe we should start writing letters again? Maybe put an encrypted usb-stick or a memory card into an envelope and mail it?
I’m not saying that I’d like to have to use this but if push comes to shove: encrypt your plain-text with aes256.
Example text:
FKZOMTF39EgMbw+Zdzqr1zEIpW6iCQBy7IfxZLHcmTzhqmpMgwdOdZhD30JrY89yPassword: 1234
Decrypted text: test
What PBKDF did you use and how is the IV included with the ciphertext?
Used the programme “DroidCrypt” from F-Droid.
DroidCrypt uses scrypt with N=32768 r=16 p=4 as PBKDF, and AES-256 in GCM mode with tag-length of 128 bits. The ciphertext is output as:
+------------------------+-----------------------+------------------------- | scrypt salt (16 bytes) | AES-GCM IV (12 bytes) | ciphertext (N bytes) ... +------------------------+-----------------------+-------------------------and base64 encoded.
Your recipient would need to know all of these details to be able to decrypt the text (or use the same app) which is why cryptography is a bit more complicated than just “encrypt it with aes256.”
