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 MustSupportFIPS140
func MustSupportFIPS140(t *testing.T)
func NoExtraMethods
func NoExtraMethods(t *testing.T, ms any, 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
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.
