Based on this tweet†, it seems that Chris downloaded the repos and put them online, encrypted using some of his personal information as a sort of "dead man's switch".
For posterity:
<14-character non-dictionary word>+<My current CA DL number>+<Streetname of my residence during 1st grade>
Schema: aaaaaaaaaaaaaa+Annnnnnn+Aaaa Aaaaaaa
(a=lower alpha, A=upper alpha, n=numeric)
md5 those 36-characters. Hash is the passphrase
Driver's license numbers are likely sequential, so the keyspace is likely guessable, or recoverable from credit data breaches. Street name is an easier find, from public records.
Since we know that non-dictionary word is 14-characters, and assuming English, entropy should much less than 26^14.
He wants us to open the file but he wants it to be annoying?
