| 描述： | Oh no, I can't log into my SSH server anymore. My RSA private key is corrupted by ransomware and I need your help recovering it. Please submit the flag as sdctf{<sha256_hash>}, where <sha256_hash> is the SHA-256 hash of the original SSH private key file as 64 lowercase hex digits. As an unrealistic hypothetical example, if the original SSH private key is the 0 byte empty file, the flag would be `sdctf{e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855}` 得到的flag使用NSSCTF{}格式提交。 |
