Explanation
- Try one seed. Read as one list, the 40 mask digits
4336110404416871136103743824562855412407fit no seed from 0 to 999, which is why this post long looked like an exception to the mask generator. - Run 1. The 19 mask digits of block 1,
4336110404416871136, are exactlynew Random(360).Next(9)after 1 discarded call. - Run 2. The 21 mask digits of block 2,
103743824562855412407, are exactlynew Random(318).Next(9)after 1 discarded call. - Two runs. Each block has its own seed, so the blank line is where one run of the generator ended and a new one, with a new
Random, began. Both runs throw away their first draw before the first mask digit; what that draw is for is not known (the later posts start at the first draw). The other 30 hex digits of each GUID areGuid.NewGuid()output and carry no message. - Conclusion. Filler: two runs of the masked-GUID generator posted together.
- Explain the count. Grouped in Before the scheduler: before the scheduled app (Jun 26 2012): sparse single tool runs / hand lists (o5o4o, jbucr, jkuyr), 2011 genuine-v4 lists; no long-lived count stream to fit
Solution summary
- Method
- two masked-GUID halves, no cipher
- Result
- 40 masked GUIDs: records 1-19 seed 360, records 20-40 seed 318
- Explanation
- Unencrypted; the blank line is a generator boundary; version nibbles fit both halves exactly (draw 0 skipped in each); the MD5-preimage reading is superseded
- Re-checked
- plain: two masked-GUID halves, blank-line seam
