data DeserializationError #

Constructors

DeserializationErrorMalformed String	Malformed JSON has syntax errors in the JSON itself (i.e., we cannot even parse it to a JSValue)
DeserializationErrorSchema String	Invalid JSON has valid syntax but invalid structure The string gives a hint about what we expected instead
DeserializationErrorUnknownKey KeyId	The JSON file contains a key ID of an unknown key
DeserializationErrorValidation String	Some verification step failed
DeserializationErrorFileType String String	Wrong file type Records actual and expected types.

data FileInfo #

File information

This intentionally does not have an Eq instance; see knownFileInfoEqual and verifyFileInfo instead.

NOTE: Throughout we compute file information always over the raw bytes. For example, when timestamp.json lists the hash of snapshot.json, this hash is computed over the actual snapshot.json file (as opposed to the canonical form of the embedded JSON). This brings it in line with the hash computed over target files, where that is the only choice available.

Utility

fileInfo :: ByteString -> FileInfo #

Compute FileInfo

TODO: Currently this will load the entire input bytestring into memory. We need to make this incremental, by computing the length and all hashes in a single traversal over the input.

computeFileInfo :: FsRoot root => Path root -> IO FileInfo #

Compute FileInfo

compareTrustedFileInfo #

Arguments

:: FileInfo	expected (from trusted TUF files)
-> FileInfo	actual (from `fileInfo` on target file)
-> Bool

Compare the expected trusted file info against the actual file info of a target file.

This should be used only when the FileInfo is already known. If we want to compare known FileInfo against a file on disk we should delay until we have confirmed that the file lengths match (see downloadedVerify).

knownFileInfoEqual :: FileInfo -> FileInfo -> Bool #

fileInfoSHA256 :: FileInfo -> Maybe Hash #

Extract SHA256 hash from FileInfo (if present)

Cache layout

data CacheLayout #

Location of the various files we cache

Although the generic TUF algorithms do not care how we organize the cache, we nonetheless specity this here because as long as there are tools which access files in the cache directly we need to define the cache layout. See also comments for defaultCacheLayout.

Constructors

CacheLayout

Fields

cacheLayoutRoot :: CachePath
TUF root metadata
cacheLayoutTimestamp :: CachePath
TUF timestamp

cacheLayoutMirrors :: CachePath

cacheLayoutIndexTar :: CachePath
Uncompressed index tarball
cacheLayoutIndexIdx :: CachePath
Index to the uncompressed index tarball
cacheLayoutIndexTarGz :: CachePath
Compressed index tarball
We cache both the compressed and the uncompressed tarballs, because incremental updates happen through the compressed tarball, but reads happen through the uncompressed one (with the help of the tarball index).

cabalCacheLayout :: CacheLayout #

The cache layout cabal-install uses

We cache the index as cache/00-index.tar; this is important because `cabal-install` expects to find it there (and does not currently go through the hackage-security library to get files from the index).

Repository layout

Layout of the files within the index tarball

Constructors

IndexLayout
Fields indexFileToPath :: forall dec. IndexFile dec -> IndexPath Translate an `IndexFile` to a path indexFileFromPath :: IndexPath -> Maybe (Some IndexFile) Parse an `FilePath`

data IndexFile :: * -> * where #

Files that we might request from the index

The type index tells us the type of the decoded file, if any. For files for which the library does not support decoding this will be (). NOTE: Clients should NOT rely on this type index being (), or they might break if we add support for parsing additional file formats in the future.

TODO: If we wanted to support legacy Hackage, we should also have a case for the global preferred-versions file. But supporting legacy Hackage will probably require more work anyway..

Definition of a mirror

NOTE: Unlike the TUF specification, we require that all mirrors must have the same format. That is, we omit metapath and targetspath.

Constructors

data MirrorContent #

Full versus partial mirrors

The TUF spec explicitly allows for partial mirrors, with the mirrors file specifying (through patterns) what is available from partial mirrors.

For now we only support full mirrors; if we wanted to add partial mirrors, we would add a second MirrorPartial constructor here with arguments corresponding to TUF's metacontent and targetscontent fields.

Constructors

MirrorFull

Repository

data RepoRoot #

The root of the repository

Repository roots can be anchored at a remote URL or a local directory.

Note that even for remote repos RepoRoot is (potentially) different from Web -- for a repository located at, say, http://hackage.haskell.org they happen to coincide, but for one location at http://example.com/some/subdirectory they do not.

Invariant: each signature must be made with a different key. We enforce this invariant for incoming untrusted data (fromPreSignatures) but not for lists of signatures that we create in code.

data Signature #

Constructors

Signature
Fields signature :: ByteString signatureKey :: Some PublicKey

Construction and verification

unsigned :: a -> Signed a #

Create a new document without any signatures

withSignatures :: ToJSON WriteJSON a => RepoLayout -> [Some Key] -> a -> Signed a #

Sign a document

withSignatures' :: ToJSON Identity a => [Some Key] -> a -> Signed a #

Variation on withSignatures that doesn't need the repo layout

signRendered :: [Some Key] -> ByteString -> Signatures #

Construct signatures for already rendered value

verifySignature :: ByteString -> Signature -> Bool #

JSON aids

signedFromJSON :: (MonadKeys m, FromJSON m a) => JSValue -> m (Signed a) #

General FromJSON instance for signed datatypes

We don't give a general FromJSON instance for Signed because for some datatypes we need to do something special (datatypes where we need to read key environments); for instance, see the "Signed Root" instance.

verifySignatures :: JSValue -> Signatures -> Bool #

Signature verification

NOTES: 1. By definition, the signature must be verified against the canonical JSON format. This means we _must_ parse and then pretty print (as we do here) because the document as stored may or may not be in canonical format. 2. However, it is important that we NOT translate from the JSValue to whatever internal datatype we are using and then back to JSValue, because that may not roundtrip: we must allow for additional fields in the JSValue that we ignore (and would therefore lose when we attempt to roundtrip). 3. We verify that all signatures are valid, but we cannot verify (here) that these signatures are signed with the right key, or that we have a sufficient number of signatures. This will be the responsibility of the calling code.

Avoid interpreting signatures

data UninterpretedSignatures a #

File with uninterpreted signatures

Sometimes we want to be able to read a file without interpreting the signatures (that is, resolving the key IDs) or doing any kind of checks on them. One advantage of this is that this allows us to read many file types without any key environment at all, which is sometimes useful.

Constructors

This corresponds precisely to the TUF representation of a signature.

Constructors

Instances

Utility

fromPreSignature :: MonadKeys m => PreSignature -> m Signature #

Convert a pre-signature to a signature

Verifies that the key type matches the advertised method.

fromPreSignatures :: MonadKeys m => [PreSignature] -> m Signatures #

Convert a list of PreSignatures to a list of Signatures

This verifies the invariant that all signatures are made with different keys. We do this on the presignatures rather than the signatures so that we can do the check on key IDs, rather than keys (the latter don't have an Ord instance).

toPreSignature :: Signature -> PreSignature #

Convert signature to pre-signature

toPreSignatures :: Signatures -> [PreSignature] #

Convert list of pre-signatures to a list of signatures

data Snapshot #

Constructors

Snapshot

Fields

snapshotVersion :: FileVersion
snapshotExpires :: FileExpires
snapshotInfoRoot :: FileInfo
File info for the root metadata
We list this explicitly in the snapshot so that we can check if we need to update the root metadata without first having to download the entire index tarball.
snapshotInfoMirrors :: FileInfo
File info for the mirror metadata
snapshotInfoTarGz :: FileInfo
Compressed index tarball
snapshotInfoTar :: Maybe FileInfo
Uncompressed index tarball
