The CIA spends considerable amounts if money in intercepting and decoding Apple Mac and iPhone devices.
A base of CIA operations is Geneva. Geneva is a center for encryption services and CIA spies float about
from one company to another. The SNP uses ProtonMail based in Geneva.
Do not use encryption based on the factorisation of primes. This is very bad. There is a quick and efficient
method to factorise large primes.
Use random encoding based say on explicit radioactive decay and do not trust anyone to generate this for you.
Radioactive decay is not secure but we think it may be likely in practice that only God can decode it! This
method means transportation of random codes between devices which can be intercepted. Do not trust any
courier for this. Do it yourself.
