...id() only adds up to 29 bits of entropy
md5() doesn't add entropy, it just mixes it deterministically
Since a 56-bit DES key can be brute-forced in about 24 hours, and an average case would have about 59 bits of entropy, we can calculate 2^59 / 2^56 = about 8 days. Depending on how this token veri...
