One isolated flaw aside, the point remains: serious encryption is available to users even if government forbids it. Yes, Blowfish had a bug - but there are numerous other well-regarded thoroughly-studied strong-encryption algorithms available ... and they’re so simple I have several on t-shirts.
Encryption will always have the risk of either bad implementation, or mathematical breakthroughs, compromising security. It’s generally accepted that implementations should be open-source (not necessarily _free_) for examination, so such flaws may be publicly discovered ASAP.
Yes, it’s magic to most users. That’s why we need a sense of trust - which we DON’T have when strangers with guns compel us to compromise our security for their benefit, especially when they’re making the demands after they failed to do a bunch of other things we’ve given them authority to do.
RSA in 3 lines of perl? I always wanted one of those. "This t-shirt is a munition"
