package async_ssl

Release v0.17.0

• Fix known compatibility issues with OpenSSL 3.x (particularly on Mac OS X and some Linux distributions)

• Added basic support for using ALPN on the client and server side for protocol selection. You can specify which protocols your support when initializing the client/server using the [?alpn_protocols] argument, and then determine which protocol was negotiated using [Tls.Connection.alpn_selected].

• Improved hostname + certificate verification logic. We now use the openssl 1.1+ verification functionality directly instead of relying on our own (much slower) logic using ocaml_x509.

Release v0.16.0

• Removed Support for OpenSSL 1.0. We now require OpenSSL 1.1.x. (OpenSSL 3.x should also work but is untested).

• Added new configuration option override_security_level as an escape hatch to override the system wide OpenSSL security level. See Ssl.Override_security_level

• Added Connection.peer_certificate_fingerprint and Certificate.fingerprint.

• Expose ?socket on Tls.listen to allow configuring the underlying listening socket. See Async_unix.Tcp.Server.create.

Old pre-v0.15 changelogs (very likely stale and incomplete)

git version

• Added function Ffi.set_default_verify_paths, to make OpenSSL use its default for CA certificates locations

113.33.00

• Make sure to close the Pipe.Writer.t that goes back to the application, otherwise the application will never get an `Eof if the connection is closed.

113.24.00

• Switched to ppx.

113.00.00

• Added Ssl.Connection.close.

112.35.00

• Fix github issue #4 (some comments swapped).

112.24.00

• By default OpenSSL ignores the result of certificate validation, so we need to tell it not to.

• Expose session details such as checked certificates and negotiated version. Add session resumption.

112.17.00

• moved ffi_bindings and ffi_stubgen in separate libraries

111.21.00

• Upgraded to use new ctypes and its new stub generation methods.

111.08.00

• Improved the propagation of SSL errors to the caller.

111.06.00
