Native Haskell TLS and SSL protocol implementation for server and client.
This provides a high-level implementation of a sensitive security protocol, eliminating a common set of security issues through the use of the advanced type system, high level constructions and common Haskell features.
Currently implement the SSL3.0, TLS1.0, TLS1.1, TLS1.2 and TLS 1.3 protocol, and support RSA and Ephemeral (Elliptic curve and regular) Diffie Hellman key exchanges, and many extensions.
Some debug tools linked with tls, are available through the http://hackage.haskell.org/package/tls-debug/.

NOTES:
- Starting with tls-1.5.0, the parameter
supportedVersions
contains values ordered by decreasing preference, so typically the higher versions first. This departs from code samples previously available. For maximum interoperability, users overriding the default value should verify and adapt their code.

- Fix recvClientData with single Handshake packet #352
- Decrease memory footprint of SessionData values #354
FEATURES:
- TLS version 1.3 is available with most features but is not enabled by default.
One notable omission is post-handshake authentication. Scenarios where
servers previously used renegotiation to conditionally request a certificate
are not possible yet when
TLS13
is negotiated. Users may enable the version insupportedVersions
only when sure post-handshake authentication is not required.
API CHANGES:
SessionManager
implementations need to provide asessionResumeOnlyOnce
function to accomodate resumption scenarios with 0-RTT data. The function is called only on the server side.- Data type
SessionData
is extended with four new fields for TLS version 1.3.SessionManager
implementations that serializes/deserializesSessionData
values must deal with the new fields. - New configuration parameters and constructors are added for TLS version 1.3 but the API change should be backward compatible for most use-cases.
- Function
cipherExchangeNeedMoreData
has been removed.
Version 1.4.1
- Enable X25519 in default parameters #265
- Checking EOF in bye #262
- Improving validation in DH key exchange #256
- Handle TCP reset during handshake #251
- Accepting hlint suggestions.
Version 1.4.0
- Wrap renegotiation failures with HandshakeFailed #237
- Improve selection of server certificate and use “signature_algorithms” extension #236
- Change Bytes to ByteString and deprecate the Bytes type alias #230
- Session compression and SNI #223
- Deprecating ciphersuite_medium. Putting WARNING to ciphersuite_all since this includes RC4 #153 #222
- Removing NPN #214
- Supporting RSAPSS defined in TLS 1.3 #207
- Supporting X25519 and X448 in the IES style. #205
- Strip leading zeros in DHE premaster secret #201
FEATURES:
- RSASSA-PSS signatures can be enabled with
supportedHashSignatures
. This uses assignments from TLS 1.3, for example(HashIntrinsic, SignatureRSApssSHA256)
. - Diffie-Hellman with elliptic curves X25519 and X448: This can be enabled with
supportedGroups
, which also gives control over curve preference. - ECDH with curve P-256 now uses optimized C implementation from package
cryptonite
.
API CHANGES:
- Cipher list
ciphersuite_medium
is now deprecated, users are advised to useciphersuite_default
orciphersuite_strong
. Listciphersuite_all
is kept for compatibility with old servers but this is discouraged and generates a warning (this includes RC4 ciphers, see #153 for reference). - Support for NPN (Next Protocol Negotiation) has been removed. The replacement is ALPN (Application-Layer Protocol Negotiation).
- Data type
SessionData
now contains fields for compression algorithm and client SNI. ASessionManager
implementation that serializes/deserializesSessionData
values must deal with the new fields. - Module
Network.TLS
exports a type alias namedBytes
which is now deprecated. The replacement is to use strictByteString
directly.
