> This one is simple! Just look where you might look at the cryptographic history of the sunshinectf.org domain! There's a Yeti in one and a Nimbus in another!
Here, we're asked to chech the cryptographic history of the challenge domain.Since we're talking about a website, it can only mean to check the history of its security certificates!
We can see it by visiting [crt.sh](crt.sh). This is an OSINT Tool aimed to gather info on certificates emitted to the certificate transparency logs,
Searching for the [given domain](https://crt.sh/?q=sunshinectf.org) we can find the flag in the identifiers set for the certificate on the 18th of november:
