of cryptography. We call the act of testing all 25 options until nding the key, the method of brute force. However, even if we couldn’t use brute force the Caesar cipher is still considered to be weak. This is because each letter of the alphabet (say \a") always gets encrypted to the same letter (which depends on your shift).

The mathematics of cryptology - UMass
cryptography is based on the following empirically observed fact (here written as if it were carved in stone): Multiplying two integers is easy, but finding a nontrivial factor of an integer is hard. In other words, integer multiplication is in practice a “one-way function.” If a number is large, it’s essentially impossible to factor it. 11
