In addition +to the website, the official source distribution is at +. The OpenSSL `README` can be found at +[README-OpenSSL.md](https://github.com/quictls/openssl/blob/OpenSSL_1_1_1w%2Bquic/README-OpenSSL.md). + +This fork adds APIs that can be used by QUIC implementations for connection +handshakes. Quoting the IETF Working group +[charter](https://datatracker.ietf.org/wg/quic/about/), QUIC is a "UDP-based, +stream-multiplexing, encrypted transport protocol." If you don't need QUIC, you +should use the official OpenSSL distributions. + +The APIs here are used by Microsoft's +[MsQuic](https://github.com/microsoft/msquic) and Google's +[Chromium QUIC](https://chromium.googlesource.com/chromium/src/+/master/net/quic/) + +We are not in competition with OpenSSL project. We informed them of +our plans to fork the code before we went public. We do not speak for the +OpenSSL project, and can only point to a +[blog post](https://www.openssl.org/blog/blog/2020/02/17/QUIC-and-OpenSSL/) and +[openssl-project email](https://github.com/quictls/openssl/discussions/54) +that provides their view of QUIC support. + +As stated in their blog post, the OpenSSL team is focused on their 3.0 release +(released 2021-09-07), and does not intend to add QUIC functionality to 1.1.x. +There is a community need for a QUIC-capable TLS library. This fork is intended +as stopgap solution to enable higher level frameworks and runtimes to use QUIC +with the proven and reliable TLS functionality from OpenSSL. This fork will be +maintained until OpenSSL officially provides reasonable support for QUIC +implementations. + +This fork can be considered a supported version of +[OpenSSL PR 8797](https://github.com/openssl/openssl/pull/8797). +We will endeavor to track OpenSSL releases within a day or so, and there is an +item below about how we'll follow their tagging. + +On to the questions and answers. + +What about branches? +-------------------- +We don't want to conflict with OpenSSL branch names. Our current plan is to append +`+quic`. Release tags are likely to be the QUIC branch with `-releaseX` appended. +For example, the OpenSSL tag `openssl-3.0.0` would have a branch named +`openssl-3.0.0+quic` and a release tag of `openssl-3.0.0+quic-release1`. + +How are you keeping current with OpenSSL? +----------------------------------------- +(In other words, "What about rebasing?") + +Our plan is to always rebase on top of an upstream release tag. In particular: +- The changes for QUIC will always be at the tip of the branch -- you will know what +is from the original OpenSSL and what is for QUIC. +- New versions are quickly created once upstream creates a new tag. +- The use of git commands (such as "cherry") can be used to ensure that all changes +have moved forward with minimal or no changes. You will be able to see "QUIC: Add X" +on all branches and the commit itself will be nearly identical on all branches, and +any changes to that can be easily identified. + +What about library names? +------------------------- +Library names will be the same, but will use a different version number. The version +numbers for the current OpenSSL libraries are `1.1` (for the 1.1.0 and 1.1.1 branches) +and `3` (for the 3.0 branch). We will be prefixing `81` (ASCII for 'Q') to +the version numbers to generate a unique version number. + +- `libcrypto.so.81.3` vs `libcrypto.so.3` +- `libcrypto.so.81.1.1` vs `libcrypto.so.1.1` +- `libssl.so.81.3` vs `libssl.so.3` +- `libssl.so.81.1.1` vs `libssl.so.1.1` + +The SONAME of these libraries are all different, guaranteeing the correct library +will be used. + +...and the executable? +---------------------- +We currently do not have any plans to change the name, mainly because we +haven't made any changes there. If you see a need, please open an issue. + +The `openssl version` command will report that it is `+quic` enabled. + +...and FIPS? +------------ +We are not doing anything with FIPS. This is actually good news: you should +be able to load the OpenSSL 3.0 FIPS module into an application built against +this fork and everything should Just Work™. + +How can I contribute? +--------------------- +We want any code here to be acceptable to OpenSSL. This means that all contributors +must have signed the appropriate +[contributor license agreements](https://www.openssl.org/policies/cla.html). We +will not ask for copies of any paperwork, you just need to tell us that you've +done so (and we might verify with OpenSSL). We are only interested in making it +easier and better for at least the mentioned QUIC implementations to use a variant +of OpenSSL. If you have a pull request that changes the TLS protocol, or adds +assembly support for a new CPU, or otherwise is not specific to enabling QUIC, +please contribute that to OpenSSL. This fork is intended to be a clean extension +to OpenSSL, with the deltas being specific to QUIC. + +Who are you? +------------ +This is a collaborative effort between [Akamai](https://www.akamai.com) and +[Microsoft](https://www.microsoft.com).

This function should be +used to limit buffering in the QUIC implementation. + +See https://tools.ietf.org/html/draft-ietf-quic-transport-27#section-4. + +SSL_quic_read_level() returns the current read encryption level. + +SSL_quic_write_level() returns the current write encryption level. + +SSL_provide_quic_data() is used to provide data from QUIC CRYPTO frames to the +state machine, at a particular encryption level B. It is an error to +call this function outside of the handshake or with an encryption level other +than the current read level. The application must buffer and consolidate any +frames with less than four bytes of content. It returns one on success and +zero on error. + +SSL_process_quic_post_handshake() processes any data that QUIC has provided +after the handshake has completed. This includes NewSessionTicket messages +sent by the server. + +SSL_is_quic() indicates whether a connection uses QUIC. A given B +or B can only be used with QUIC or TLS, but not both. + +SSL_set_quic_use_legacy_codepoint() specifies the legacy extension codepoint +in manner compatible with some versions of BoringSSL. + +SSL_set_quic_transport_version() specifies the quic transport version that +allows for backwards and forwards compatibility. If set to 0 (default) the +server will use the highest version the client sent. If set to 0 (default) +the client will send both extensions. + +SSL_get_quic_transport_version() returns the value set by +SSL_set_quic_transport_version(). + +SSL_get_peer_quic_transport_version() returns the version the that was +negotiated. + +SSL_set_quic_early_data_enabled() enables QUIC early data if a nonzero +value is passed. Clients must set a resumed session before calling this +function. Servers must additionally call SSL_CTX_set_max_early_data() or +SSL_set_max_early_data() with 0xffffffffu as the argument, so that any +issued session tickets indicate that server is able to accept early data. + +=head1 NOTES + +These APIs are implementations of BoringSSL's QUIC APIs. + +QUIC acts as an underlying transport for the TLS 1.3 handshake. The following +functions allow a QUIC implementation to serve as the underlying transport as +described in draft-ietf-quic-tls. + +When configured for QUIC, SSL_do_handshake() will drive the handshake as +before, but it will not use the configured B. It will call functions from +the configured B to configure secrets and send data. If data +is needed from the peer, it will return B. When received, +the caller should call SSL_provide_quic_data() and then SSL_do_handshake() to +continue the handshake. After the handshake is complete, the caller should call +SSL_provide_quic_data() for any post-handshake data, followed by +SSL_process_quic_post_handshake() to process it. It is an error to call +SSL_read()/SSL_read_ex() and SSL_write()/SSL_write_ex() in QUIC. + +Note that secrets for an encryption level may be available to QUIC before the +level is active in TLS. Callers should use SSL_quic_read_level() to determine +the active read level for SSL_provide_quic_data(). SSL_do_handshake() will +pass the active write level to add_handshake_data() when writing data. Callers +can use SSL_quic_write_level() to query the active write level when +generating their own errors. + +See https://tools.ietf.org/html/draft-ietf-quic-tls-27#section-4.1 for more +details. + +To avoid DoS attacks, the QUIC implementation must limit the amount of data +being queued up. The implementation can call +SSL_quic_max_handshake_flight_len() to get the maximum buffer length at each +encryption level. + +draft-ietf-quic-tls defines a new TLS extension "quic_transport_parameters" +used by QUIC for each endpoint to unilaterally declare its supported +transport parameters. The contents of the extension are specified in +https://tools.ietf.org/html/draft-ietf-quic-transport-27#section-18 (as +a sequence of tag/length/value parameters) along with the interpretation of the +various parameters and the rules for their processing. + +OpenSSL handles this extension as an opaque byte string. The caller is +responsible for serializing and parsing it. + +=head2 OSSL_ENCRYPTION_LEVEL + +B (B) represents the +encryption levels: + +=over 4 + +=item ssl_encryption_initial + +The initial encryption level that is used for client and server hellos. + +=item ssl_encryption_early_data + +The encryption level for early data. This is a write-level for the client +and a read-level for the server. + +=item ssl_encryption_handshake + +The encryption level for the remainder of the handshake. + +=item ssl_encryption_application + +The encryption level for the application data. + +=back + +=head2 SSL_QUIC_METHOD + +The B (B) describes the +QUIC methods. + + struct ssl_quic_method_st { + int (*set_encryption_secrets)(SSL *ssl, OSSL_ENCRYPTION_LEVEL level, + const uint8_t *read_secret, + const uint8_t *write_secret, size_t secret_len); + int (*add_handshake_data)(SSL *ssl, OSSL_ENCRYPTION_LEVEL level, + const uint8_t *data, size_t len); + int (*flush_flight)(SSL *ssl); + int (*send_alert)(SSL *ssl, enum ssl_encryption_level_t level, uint8_t alert); + }; + typedef struct ssl_quic_method_st SSL_QUIC_METHOD; + +set_encryption_secrets() configures the read and write secrets for the given +encryption level. This function will always be called before an encryption +level other than B is used. Note, however, that +secrets for a level may be configured before TLS is ready to send or accept +data at that level. + +When reading packets at a given level, the QUIC implementation must send +ACKs at the same level, so this function provides read and write secrets +together. The exception is B, where secrets are +only available in the client to server direction. The other secret will be +NULL. The server acknowledges such data at B, +which will be configured in the same SSL_do_handshake() call. + +This function should use SSL_get_current_cipher() to determine the TLS +cipher suite. + +add_handshake_data() adds handshake data to the current flight at the given +encryption level. It returns one on success and zero on error. + +OpenSSL will pack data from a single encryption level together, but a +single handshake flight may include multiple encryption levels. Callers +should defer writing data to the network until flush_flight() to better +pack QUIC packets into transport datagrams. + +flush_flight() is called when the current flight is complete and should be +written to the transport. Note a flight may contain data at several +encryption levels. + +send_alert() sends a fatal alert at the specified encryption level. + +All QUIC methods return 1 on success and 0 on error. + +=head1 RETURN VALUES + +SSL_CTX_set_quic_method(), +SSL_set_quic_method(), +SSL_set_quic_transport_params(), and +SSL_process_quic_post_handshake() +return 1 on success, and 0 on error. + +SSL_quic_read_level() and SSL_quic_write_level() return the current +encryption level as an B +(B). + +SSL_quic_max_handshake_flight_len() returns the maximum length in bytes of a +flight for a given encryption level. + +SSL_is_quic() returns 1 if QUIC is being used, 0 if not. + +=head1 SEE ALSO + +L, L, L + +=head1 HISTORY + +These functions were added in OpenSSL 3.0.0. + +=head1 COPYRIGHT + +Copyright 2019 The OpenSSL Project Authors.
