+           
+           Let's check `src/app/api/auth/register/route.ts` OR how I used it in export.

+           
+           If I look at `import` route:

+           const [newUser] = await db.insert(users).values({ ... privateKeyEncrypted: privateKey ... })
+           Wait, in import route I decrypt it using the password, then I insert it...
+           WAIT. The import route inserts `privateKeyEncrypted: privateKey`. 
+           This implies `privateKeyEncrypted` column implies it SHOULD be encrypted, but if I'm inserting the RAW private key there... that's bad.
