PGP dual-key encryption is probably secure. There is no evidence anyone has ever cracked it, including the government. And you don't have to meet the person in real life to give them the key. You just send them the public key and they use that to send encrypted messages to you. The system revolutionized secret communication when it was invented in the 1970s.
If you can contradict what I say below, I am all ears. I know your expertise surpasses mine in this area. Though I am but a school boy in this subject, I attended the school of Zimmerman, the Cypherpunks, and others.
Truly, PGP was both genius and convenient in its day, but PGP can be broken by "brute strength" attacks. If you are a priority target, you will be subjected to the necessary "brute strength" of Super-Cray computers.
A fortiori, China's Xiaohong-504 and .ZOG's Willow quantum chips are now the "brute" necessary to break PGP. Breaking any current encryption is possible today and will become trivial in the coming days. Relying upon today's encryption is like sending postcards through the USPS.
When able, I have avoided all NIST standard encryption, preferring to nest layers of non-NIST algorithms.
Seriously, in all fraternal respect, I hope to be edified by your expertise.
