Explanation
- Read the length. 656 hex characters = 64 × 10 + 16, i.e. N = 10 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 143 of Run 71 (seed 1,220,915,585):
new Random(1220915585), Next(10,24) per post. The RNG predicts N = 10; the post has N = 10 ✓. The seed is the machine's uptime in ms when the app started (boot 2015-11-17 20:51–21:51). - Conclusion. Filler. Structure and count are explained; the GUIDs are presumed filler like every decrypted post before the cutover.
