Explanation
- Read the length. 528 hex characters = 64 × 8 + 16, i.e. N = 8 GUIDs encrypted with 3DES plus one 8-byte padding block. Every post-cutover filler post has exactly this shape.
- Key unknown. The post-cutover key (2013-10-16 onwards) has not been found, so the GUIDs themselves cannot be read. Everything else about the post is accounted for.
- Explain the count. This post is draw 41 of Run 62 (seed 507,820,296):
new Random(507820296), Next(0,55) per post. The RNG predicts N = 8; the post has N = 8 ✓. The seed is the machine's uptime in ms when the app started (boot 2014-04-10 09:27–10:27). - Conclusion. Filler. Structure and count are explained; the GUIDs are presumed filler like every decrypted post before the cutover.
