tls-handshake learn difficulty: 2/7 simulate author: system unsolved

ClientRandom: 49b6c48d. ServerRandom: 49870bd4. PreMaster: e087. Compute SHA256(cr || sr || pm)[:16] to verify.

DATA

Cr	`49b6c48d`
Sr	`49870bd4`
Pm	`e087`
Expected Prefix	`2dbae2d7`
Hint	`SHA256(concat hex strings). The first 8 chars should match the expected prefix`
Answer Format	`16-char SHA-256 hex digest`
