Crypt::Random::TESHA2 generate random numbers using entropy gathered from timer/scheduler jitter. This can be used to generate non-pseudorandom data to seed a PRNG (e.g. srand/rand, Math::Random::MT, etc.) or CSPRNG (e.g. AES-CTR or Math::Random::ISAAC). You may use it directly or as part of a random source module that first checks for O/S randomness sources.
Binary packages can be installed with the high-level tool pkgin (which can be installed with pkg_add) or pkg_add(1) (installed by default). The NetBSD packages collection is also designed to permit easy installation from source.
The pkg_admin audit command locates any installed package which has been mentioned in security advisories as having vulnerabilities.
Please note the vulnerabilities database might not be fully accurate, and not every bug is exploitable with every configuration.
Problem reports, updates or suggestions for this package should be reported with send-pr.
