Re: Masking seed phrases for an extra layer of security (experimental)
I fail to see the point.
Unless you have a Ph.D. in cryptography, don't invent your own safety layers; they tend to bite you in the ass sooner or later.
Agreed. No sense to spend the time reinventing the wheel. PGP encryption has been around for over two decades and is the proven and robust scheme. When applied to SEED phrases, it renders them indistinguishable from any other encrypted message, which is ideal for masking purposes. I can't think of more effective or widely trusted method for this use case. BTW, relevant private PGP key can be securely cloned onto multiple hardware dongles.
And yet, PGP has been compromised countless times in the past, causing huge monetary losses and forcing users to leave the forum.
That was largely due to poor key management, human error, and some flawed implementation choices such as using weaker algorithms or shorter keys. When implemented properly and with modern cryptographic primitives, PGP itself has never been fundamentally compromised. That said, go ahead, you are free "to invent the wheel" to use it for SEED phrase masking.
