Jae Kwon	536c27de8e	common/random.go supports seeding and Rand (#121 ) common/random.go supports seeding and Rand Ensure determinism	7 years ago
Emmanuel Odeke	8638961f02	common: Rand* warnings about cryptographic unsafety Lesson articulated by @jaekwon on why we need 80 bits of entropy at least before we can think of cryptographic safety. math/rand's seed is a max of 64 bits so can never be cryptographically secure. Also added some benchmarks for RandBytes	7 years ago
Emmanuel Odeke	cdc7988823	common: use genius simplification of tests from @ebuchman Massive test simplication for more reliable tests from @ebuchman	7 years ago
Ethan Buchman	b5f465b4ec	common: use names prng and mrand	7 years ago
Emmanuel Odeke	29471d75cb	common: no more relying on math/rand.DefaultSource Fixes https://github.com/tendermint/tmlibs/issues/99 Updates https://github.com/tendermint/tendermint/issues/973 Removed usages of math/rand.DefaultSource in favour of our own source that's seeded with a completely random source and is safe for use in concurrent in multiple goroutines. Also extend some functionality that the stdlib exposes such as * RandPerm * RandIntn * RandInt31 * RandInt63 Also added an integration test whose purpose is to be run as a consistency check to ensure that our results never repeat hence that our internal PRNG is uniquely seeded each time. This integration test can be triggered by setting environment variable: `TENDERMINT_INTEGRATION_TESTS=true` for example ```shell TENDERMINT_INTEGRATION_TESTS=true go test ```	7 years ago
