Go 1.21.0 was released in August 2023, so our upcoming release
will no longer support the Go 1.20 release series.
The first Go 1.22 release candidate is also due in December 2023,
less than a month from now, so dropping 1.20 will simplify 1.22 work.
Without hardening, obfuscation is vulnerable to analysis via symbolic
execution because all keys are opened, and it is easy to trace their
connections. Added extendable (contribution-friendly) hardening
mechanism that makes it harder to determine relationship between key and
execution block through key obfuscation.
There are 2 hardeners implemented and both are compatible with literal
obfuscation, which can make analysis even more difficult.
