Package-Level Type Names (total 2, neither is exported)

	/* sort exporteds by: alphabet | popularity */
	/* 2 unexporteds ... *//* 2 unexporteds: */
	 type defaultReader = drbg.DefaultReader (struct)
		defaultReader aliases [drbg.DefaultReader], so that [reader]
		does not have an exported DefaultReader field.

	 type reader (struct)

		Fields (only one, which is unexported)

Package-Level Functions (total 4, in which 3 are exported)

	 func CustomReader(r io.Reader) io.Reader
		CustomReader returns [Reader] or, only if the GODEBUG setting
		"cryptocustomrand=1" is set, the provided io.Reader.
		
		If returning a non-default Reader, it calls [randutil.MaybeReadByte] on it,
		unless it's the global testing Reader set with [SetTestingReader].

	 func IsDefaultReader(r io.Reader) bool
		IsDefaultReader reports whether r is the default [crypto/rand.Reader].
		
		If true, the Read method of r can be assumed to call [drbg.Read].

	 func SetTestingReader(r io.Reader)
		SetTestingReader overrides all calls to [drbg.Read]. The Read method of
		r must never return an error or return short.
		
		SetTestingReader panics when building against Go Cryptographic Module v1.0.0.
		
		SetTestingReader is pulled by [testing/cryptotest.SetGlobalRandom] via go:linkname.

Package-Level Variables (total 3, in which 1 is exported)

	  var Reader io.Reader
		Reader is an io.Reader that calls [drbg.Read].
		
		It should be used internally instead of [crypto/rand.Reader], because the
		latter can be set by applications outside of tests. These applications then
		risk breaking between Go releases, if the way the Reader is used changes.
