		Package cryptotest provides deterministic random source testing.


Package-Level Functions (only one)


	
		SetGlobalRandom sets a global, deterministic cryptographic randomness source
		for the duration of test t. It affects crypto/rand, and all implicit sources
		of cryptographic randomness in the crypto/... packages.
		
		SetGlobalRandom may be called multiple times in the same test to reset the
		random stream or change the seed.
		
		Because SetGlobalRandom affects the whole process, it cannot be used in
		parallel tests or tests with parallel ancestors.
		
		Note that the way cryptographic algorithms use randomness is generally not
		specified and may change over time. Thus, if a test expects a specific output
		from a cryptographic function, it may fail in the future even if it uses
		SetGlobalRandom.
		
		SetGlobalRandom is not supported when building against the Go Cryptographic
		Module v1.0.0 (i.e. when [crypto/fips140.Version] returns "v1.0.0").
