Have at it old man! 2**4096 = 10**410. With current supercomputers (10**21 computations per second), if you had about 1,000,000 (10**6) of them set up to operate in a massively parallel manner- with the correct decryption software already installed- I would estimate that it would take about only about 10**375 years to have half a chance of solving the encryption (3.1*10**7 seconds to a year). That assumes of course that you needed to only use one computation per decryption option.
10**375 = 1,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000, 000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000, 000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000, 000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000, 000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000, 000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000, 000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000, 000,000,000,000,000,000. |
