Last year the encrypted sections were encrypted using AES. I don't recall the strength used, but the minimum for AES is 128 bits.
The largest ever publicly known brute force attack was of an RC5-64 key. It took a distributed computing network 1,757 days to complete the attack. The 64 bit key cracked would take a maximum of 1.84*10^19 operations to brute force. The 128 bit minimum key used in AES would take 3.4*10^38 operations. Assuming you had access to a distributed network the size of the one used for the RC5-64 crack it would take almost 10^20 years to complete the crack.
In addition there are only 3 publicly known breaks of AES (all sidechannel breaks based on specific implementations) allowing for decryption faster than brute-force. One requires physical access to the machine that performed the encryption. Another only works for encrypted ZIP archives create using WinZIP. The third is only valid for OpenSSL.
All three breaks are completely irrelevant here. I trust that if the encryption is good enough for goverment documents of SECRET (min. 128 bit AES) or TOP SECRET (min. 256 bit AES) levels than it is good enough for a few days of any high school students or team mentors that want to try to crack it.
