Types

type ShieldedRandReader

type ShieldedRandReader struct {
	// contains filtered or unexported fields
}

ShieldedRandReader is a random bytes reader that use a cryptographically secure pseudorandom number generator for seeding quick random number generator such as xorshift++ and let it generate limited number of random numbers. After reaching the limit, it will reseed the quick random number generator with a new seed from the cryptographically secure pseudorandom number generator. by default, it will use the Xoshiro256pp source and generate 16k batches of random bytes.
