I really enjoyed Cryptonomicon by Neal Stephenson, the subject of cryptography and encryption in general is a strong theme in the book.
One of his characters looked at the length of the encryption key that another was asking him to use, and then tried to calculate the others planning horizon- essentially asking "how long, given Moore's law and so forth, will it be before a 4,096 bit encryption key could be brute forced by computational means?" and came up with roughly a century before the message would be able to be decrypted by a government agency.
