  • Read the ciphertext. Strip whitespace: 3,856 hex characters = 1,928 bytes = 241 8-byte 3DES blocks.
  • Derive the key. Password = A858DE45F56D9BC9201304032223 (name+title). Key = MD5(password) = f80873c23d59e77ceafa1cd12cb4bc2c, used as a two-key 3DES key.
  • Decrypt. 3DES-EDE2 in ECB mode, then strip the PKCS7 padding. The plaintext is 60 GUIDs as hex (shown below).

Explanation

  1. Explain the mask digits. The version nibble (13th hex digit) of each GUID, read in order, gives 002880257260231422288186866605311114287412585861180812481501. Exactly this sequence comes out of new Random(686).Next(9): the per-post millisecond seed of the mask generator. The other 30 hex digits of each GUID are Guid.NewGuid() output and carry no message.
  2. Conclusion. Filler. The GUIDs are fully explained by the mask-digit RNG; no count stream is placed for this post.
