+ Checking `src/app/api/auth/register/route.ts` would be ideal, but I don't have it open.

+ encryptPrivateKey(privateKey, password) returning { encrypted, salt, iv }
+
+ BUT the database schema `users` table has:
+ privateKeyEncrypted: text('private_key_encrypted'),
+
+ I need to know how it's stored in the DB. Is it a JSON string?
+ Or perhaps `privateKeyEncrypted` is JUST the base64 string and salt/iv are stored elsewhere?
+
+ Let's check `src/app/api/auth/register/route.ts` OR how I used it in export.
+ In export route I WROTE `encryptPrivateKey` myself.
+
+ Let's look at `src/db/schema.ts` lines 36-37:
+ privateKeyEncrypted: text('private_key_encrypted'),
+
+ If I look at `import` route:
+ It takes the exported JSON (which has separated fields) and creates the user.
+ 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.
+
+ Let's verify `src/app/api/account/import/route.ts`.
