Is it possible to crack RSA encryption?

Question

Cryptography

Is it possible to crack RSA encryption?
Key length - 8192 bits

Answer 1

A soldering iron in the fifth point breaks any cryptoalgorithm.
And if about mathematical methods - it depends on the length of the key and on the algorithm for generating this key.
By brute force - everything can be hacked, it's a matter of time and speed of the brute force (if the key is large enough, and the algorithm does not have vulnerabilities that can reduce the brute force by many orders of magnitude, then the brute force can take many decillions of years if you use the computing power of the equipment of earthlings)

Answer 2

Let's say I can factorize an 8192-bit number in my head, what's next? How to get the encrypted message itself and find out the public key?
