Functions

func FetchModule

func FetchModule(t *testing.T, module, version string) string

FetchModule fetches the module at the given version and returns the directory containing its source tree. It skips the test if fetching modules is not possible in this environment.

func SkipTestAllocations

func SkipTestAllocations(t *testing.T)

SkipTestAllocations skips the test if there are any factors that interfere with allocation optimizations.

func TestAEAD

func TestAEAD(t *testing.T, mAEAD MakeAEAD)

TestAEAD performs a set of tests on cipher.AEAD implementations, checking the documented requirements of NonceSize, Overhead, Seal and Open.

func TestAllImplementations

func TestAllImplementations(t *testing.T, pkg string, f func(t *testing.T))

TestAllImplementations runs the provided test function with each available implementation of the package registered with crypto/internal/impl. If there are no alternative implementations for pkg, f is invoked directly once.

func TestBlock

func TestBlock(t *testing.T, keySize int, mb MakeBlock)

TestBlock performs a set of tests on cipher.Block implementations, checking the documented requirements of BlockSize, Encrypt, and Decrypt.

func TestBlockMode

func TestBlockMode(t *testing.T, block cipher.Block, makeEncrypter, makeDecrypter MakeBlockMode)

TestBlockMode performs a set of tests on cipher.BlockMode implementations, checking the documented requirements of CryptBlocks.

func TestHash

func TestHash(t *testing.T, mh MakeHash)

TestHash performs a set of tests on hash.Hash implementations, checking the documented requirements of Write, Sum, Reset, Size, and BlockSize.

func TestStream

func TestStream(t *testing.T, ms MakeStream)

TestStream performs a set of tests on cipher.Stream implementations, checking the documented requirements of XORKeyStream.

func TestStreamFromBlock

func TestStreamFromBlock(t *testing.T, block cipher.Block, blockMode func(b cipher.Block, iv []byte) cipher.Stream)

TestStreamFromBlock creates a Stream from a cipher.Block used in a cipher.BlockMode. It addresses Issue 68377 by checking for a panic when the BlockMode uses an IV with incorrect length. For a valid IV, it also runs all TestStream tests on the resulting stream.

Types

type MakeAEAD

type MakeAEAD func() (cipher.AEAD, error)

MakeAEAD returns a cipher.AEAD instance.

Multiple calls to MakeAEAD must return equivalent instances, so for example the key must be fixed.

type MakeBlock

type MakeBlock func(key []byte) (cipher.Block, error)

type MakeBlockMode

type MakeBlockMode func(b cipher.Block, iv []byte) cipher.BlockMode

MakeBlockMode returns a cipher.BlockMode instance. It expects len(iv) == b.BlockSize().

type MakeHash

type MakeHash func() hash.Hash

type MakeStream

type MakeStream func() cipher.Stream

MakeStream returns a cipher.Stream instance.

Multiple calls to MakeStream must return equivalent instances, so for example the key and/or IV must be fixed.
