| Insecure encryption
| Originally Pia packets used AES-ECB encryption. As documented [https://github.com/Kinnay/NintendoClients/wiki/Pia-Overview here] it was later changed with v5.7.0 to AES-GCM. Each 0x10-byte block would have the same encrypted block output where the plaintext 0x10-byte data is the same.
The mechanism for generating the Pia SessionKey for LAN has also changed over time.
The [https://github.com/Kinnay/NintendoClients/wiki/LAN-Protocol LAN] non-Pia-encapsulated packets were also originally sent in plaintext, however at some point it was changed to mostly encrypted.
