318 | - cookies are either v10 or v11 | |
319 | - v10: AES-CBC encrypted with a fixed key | |
320 | - v11: AES-CBC encrypted with an OS protected key (keyring) | |
321 | - v11 keys can be stored in various places depending on the activate desktop environment [2] | |
322 | ||
323 | Mac: | |
324 | - cookies are either v10 or not v10 | |
325 | - v10: AES-CBC encrypted with an OS protected key (keyring) and more key derivation iterations than linux | |
326 | - not v10: 'old data' stored as plaintext | |
327 | ||
328 | Windows: | |
329 | - cookies are either v10 or not v10 | |
330 | - v10: AES-GCM encrypted with a key which is encrypted with DPAPI | |
331 | - not v10: encrypted with DPAPI | |
