Dev Ojha	2756be5a59	libs: Remove usage of custom Fmt, in favor of fmt.Sprintf (#2199 ) * libs: Remove usage of custom Fmt, in favor of fmt.Sprintf Closes #2193 * Fix bug that was masked by custom Fmt!	6 years ago
Dev Ojha	023bb99eb0	p2p: Add test vectors for deriving secrets (#2120 ) These test vectors are needed for comparison with the Rust implementation. To implement this effectively, a "RandBool" method was added to cmn.Rand.	6 years ago
ValarDragon	99e582d79a	crypto: Refactor to move files out of the top level directory Currently the top level directory contains basically all of the code for the crypto package. This PR moves the crypto code into submodules in a similar manner to what `golang/x/crypto` does. This improves code organization. Ref discussion: https://github.com/tendermint/tendermint/pull/1966 Closes #1956	6 years ago
Dev Ojha	71859f8f3b	common/rand: Remove exponential distribution functions (#1979 ) We were computing these functions incorrectly. I'm not sure what distribution these numbers are, but it isn't the normal exponential distribution. (We're making the probability of getting a number of a particular bitlength equal, but the number in that bitlength thats gets chosen is uniformly chosen) We weren't using these functions anywhere in our codebase, and they had a nomenclature error. (There aren't exponentially distributed integers, instead they would be geometrically distributed)	6 years ago
ValarDragon	a3df06d081	libs/common/rand: Update godocs The godocs fell out of sync with the code here. Additionally we had warning that these randomness functions weren't for cryptographic use on every function. However these warnings are confusing, since there was no implication that they would be secure there, and a single warning on the actual Rand type would suffice. (This is what is done in golang's math/rand godoc) Additionally we indicated that rand.Bytes() was reading OS randomness but in fact that had been changed.	6 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
