Package-Level Type Names (total 5)

/* sort by: alphabet | popularity */

type MakeAEAD (func) MakeAEAD returns a cipher.AEAD instance. Multiple calls to MakeAEAD must return equivalent instances, so for example the key must be fixed. As Inputs Of (at least one exported) func TestAEAD(t *testing.T, mAEAD MakeAEAD)

type MakeBlock (func) As Inputs Of (at least one exported) func TestBlock(t *testing.T, keySize int, mb MakeBlock)

type MakeBlockMode (func) MakeBlockMode returns a cipher.BlockMode instance. It expects len(iv) == b.BlockSize(). As Inputs Of (at least one exported) func TestBlockMode(t *testing.T, block cipher.Block, makeEncrypter, makeDecrypter MakeBlockMode)

type MakeHash (func) As Inputs Of (at least one exported) func TestHash(t *testing.T, mh MakeHash)

type MakeStream (func) 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. As Inputs Of (at least one exported) func TestStream(t *testing.T, ms MakeStream)

Package-Level Functions (total 10)

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 NoExtraMethods(t *testing.T, ms interface{}, allowed ...string) NoExtraMethods checks that the concrete type of *ms has no exported methods beyond the methods of the interface type of *ms, and any others specified in the allowed list. These methods are accessible through interface upgrades, so they end up part of the API even if undocumented per Hyrum's Law. ms must be a pointer to a non-nil interface.

func SkipTestAllocations(t *testing.T) SkipTestAllocations skips the test if there are any factors that interfere with allocation optimizations.

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(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(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(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(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(t *testing.T, ms MakeStream) TestStream performs a set of tests on cipher.Stream implementations, checking the documented requirements of XORKeyStream.

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.
