- One or more long-time support (LTS) branches: these only get bug fixes and
security fixes. Currently, the only supported LTS branch is:
[`mbedtls-2.28`](https://github.com/Mbed-TLS/mbedtls/tree/mbedtls-2.28).
- For a short time we also have the previous LTS, which has recently ended its
support period,
[`mbedtls-2.16`](https://github.com/Mbed-TLS/mbedtls/tree/mbedtls-2.16).
This branch will move into the `archive` namespace around the time of
the next release.
We retain a number of historical branches, whose names are prefixed by `archive/`,
such as [`archive/mbedtls-2.7`](https://github.com/Mbed-TLS/mbedtls/tree/archive/mbedtls-2.7).

mbed TLS ChangeLog (Sorted per branch, date)
Mbed TLS ChangeLog (Sorted per branch, date)
= Mbed TLS 3.2.0 branch released 2022-07-11
Default behavior changes
* mbedtls_cipher_set_iv will now fail with ChaCha20 and ChaCha20+Poly1305
for IV lengths other than 12. The library was silently overwriting this
length with 12, but did not inform the caller about it. Fixes #4301.
Requirement changes
* The library will no longer compile out of the box on a platform without
setbuf(). If your platform does not have setbuf(), you can configure an
alternative function by enabling MBEDTLS_PLATFORM_SETBUF_ALT or
MBEDTLS_PLATFORM_SETBUF_MACRO.
New deprecations
* Deprecate mbedtls_ssl_conf_max_version() and
mbedtls_ssl_conf_min_version() in favor of
mbedtls_ssl_conf_max_tls_version() and
mbedtls_ssl_conf_min_tls_version().
* Deprecate mbedtls_cipher_setup_psa(). Use psa_aead_xxx() or
psa_cipher_xxx() directly instead.
* Secure element drivers enabled by MBEDTLS_PSA_CRYPTO_SE_C are deprecated.
This was intended as an experimental feature, but had not been explicitly
documented as such. Use opaque drivers with the interface enabled by
MBEDTLS_PSA_CRYPTO_DRIVERS instead.
* Deprecate mbedtls_ssl_conf_sig_hashes() in favor of the more generic
mbedtls_ssl_conf_sig_algs(). Signature algorithms for the TLS 1.2 and
TLS 1.3 handshake should now be configured with
mbedtls_ssl_conf_sig_algs().
Features
* Add accessor to obtain ciphersuite id from ssl context.
* Add accessors to get members from ciphersuite info.
* Add mbedtls_ssl_ticket_rotate() for external ticket rotation.
* Add accessor to get the raw buffer pointer from a PEM context.
* The structures mbedtls_ssl_config and mbedtls_ssl_context now store
a piece of user data which is reserved for the application. The user
data can be either a pointer or an integer.
* Add an accessor function to get the configuration associated with
an SSL context.
* Add a function to access the protocol version from an SSL context in a
form that's easy to compare. Fixes #5407.
* Add function mbedtls_md_info_from_ctx() to recall the message digest
information that was used to set up a message digest context.
* Add ALPN support in TLS 1.3 clients.
* Add server certificate selection callback near end of Client Hello.
Register callback with mbedtls_ssl_conf_cert_cb().
* Provide mechanism to reset handshake cert list by calling
mbedtls_ssl_set_hs_own_cert() with NULL value for own_cert param.
* Add accessor mbedtls_ssl_get_hs_sni() to retrieve SNI from within
cert callback (mbedtls_ssl_conf_cert_cb()) during handshake.
* The X.509 module now uses PSA hash acceleration if present.
* Add support for psa crypto key derivation for elliptic curve
keys. Fixes #3260.
* Add function mbedtls_timing_get_final_delay() to access the private
final delay field in an mbedtls_timing_delay_context, as requested in
#5183.
* Add mbedtls_pk_sign_ext() which allows generating RSA-PSS signatures when
PSA Crypto is enabled.
* Add function mbedtls_ecp_export() to export ECP key pair parameters.
Fixes #4838.
* Add function mbedtls_ssl_is_handshake_over() to enable querying if the SSL
Handshake has completed or not, and thus whether to continue calling
mbedtls_ssl_handshake_step(), requested in #4383.
* Add the function mbedtls_ssl_get_own_cid() to access our own connection id
within mbedtls_ssl_context, as requested in #5184.
* Introduce mbedtls_ssl_hs_cb_t typedef for use with
mbedtls_ssl_conf_cert_cb() and perhaps future callbacks
during TLS handshake.
* Add functions mbedtls_ssl_conf_max_tls_version() and
mbedtls_ssl_conf_min_tls_version() that use a single value to specify
the protocol version.
* Extend the existing PSA_ALG_TLS12_PSK_TO_MS() algorithm to support
mixed-PSK. Add an optional input PSA_KEY_DERIVATION_INPUT_OTHER_SECRET
holding the other secret.
* When MBEDTLS_PSA_CRYPTO_CONFIG is enabled, you may list the PSA crypto
feature requirements in the file named by the new macro
MBEDTLS_PSA_CRYPTO_CONFIG_FILE instead of the default psa/crypto_config.h.
Furthermore you may name an additional file to include after the main
file with the macro MBEDTLS_PSA_CRYPTO_USER_CONFIG_FILE.
* Add the function mbedtls_x509_crt_has_ext_type() to access the ext types
field within mbedtls_x509_crt context, as requested in #5585.
* Add HKDF-Expand and HKDF-Extract as separate algorithms in the PSA API.
* Add support for the ARMv8 SHA-2 acceleration instructions when building
for Aarch64.
* Add support for authentication of TLS 1.3 clients by TLS 1.3 servers.
* Add support for server HelloRetryRequest message. The TLS 1.3 client is
now capable of negotiating another shared secret if the one sent in its
first ClientHello was not suitable to the server.
* Add support for client-side TLS version negotiation. If both TLS 1.2 and
TLS 1.3 protocols are enabled in the build of Mbed TLS, the TLS client now
negotiates TLS 1.3 or TLS 1.2 with TLS servers.
* Enable building of Mbed TLS with TLS 1.3 protocol support but without TLS
1.2 protocol support.
* Mbed TLS provides an implementation of a TLS 1.3 server (ephemeral key
establishment only). See docs/architecture/tls13-support.md for a
description of the support. The MBEDTLS_SSL_PROTO_TLS1_3 and
MBEDTLS_SSL_SRV_C configuration options control this.
* Add accessors to configure DN hints for certificate request:
mbedtls_ssl_conf_dn_hints() and mbedtls_ssl_set_hs_dn_hints()
* The configuration option MBEDTLS_USE_PSA_CRYPTO, which previously
affected only a limited subset of crypto operations in TLS, X.509 and PK,
now causes most of them to be done using PSA Crypto; see
docs/use-psa-crypto.md for the list of exceptions.
* The function mbedtls_pk_setup_opaque() now supports RSA key pairs as well.
Opaque keys can now be used everywhere a private key is expected in the
TLS and X.509 modules.
* Opaque pre-shared keys for TLS, provisioned with
mbedtls_ssl_conf_psk_opaque() or mbedtls_ssl_set_hs_psk_opaque(), which
previously only worked for "pure" PSK key exchange, now can also be used
for the "mixed" PSK key exchanges as well: ECDHE-PSK, DHE-PSK, RSA-PSK.
* cmake now detects if it is being built as a sub-project, and in that case
disables the target export/installation and package configuration.
* Make USE_PSA_CRYPTO compatible with KEY_ID_ENCODES_OWNER. Fixes #5259.
* Add example programs cipher_aead_demo.c, md_hmac_demo.c, aead_demo.c
and hmac_demo.c, which use PSA and the md/cipher interfaces side
by side in order to illustrate how the operation is performed in PSA.
Addresses #5208.
Security
* Zeroize dynamically-allocated buffers used by the PSA Crypto key storage
module before freeing them. These buffers contain secret key material, and
could thus potentially leak the key through freed heap.
* Fix potential memory leak inside mbedtls_ssl_cache_set() with
an invalid session id length.
* Add the platform function mbedtls_setbuf() to allow buffering to be
disabled on stdio files, to stop secrets loaded from said files being
potentially left in memory after file operations. Reported by
Glenn Strauss.
* Fix a potential heap buffer overread in TLS 1.2 server-side when
MBEDTLS_USE_PSA_CRYPTO is enabled, an opaque key (created with
mbedtls_pk_setup_opaque()) is provisioned, and a static ECDH ciphersuite
is selected. This may result in an application crash or potentially an
information leak.
* Fix a buffer overread in DTLS ClientHello parsing in servers with
MBEDTLS_SSL_DTLS_CLIENT_PORT_REUSE enabled. An unauthenticated client
or a man-in-the-middle could cause a DTLS server to read up to 255 bytes
after the end of the SSL input buffer. The buffer overread only happens
when MBEDTLS_SSL_IN_CONTENT_LEN is less than a threshold that depends on
the exact configuration: 258 bytes if using mbedtls_ssl_cookie_check(),
and possibly up to 571 bytes with a custom cookie check function.
Reported by the Cybeats PSI Team.
* Fix a buffer overread in TLS 1.3 Certificate parsing. An unauthenticated
client or server could cause an MbedTLS server or client to overread up
to 64 kBytes of data and potentially overread the input buffer by that
amount minus the size of the input buffer. As overread data undergoes
various checks, the likelihood of reaching the boundary of the input
buffer is rather small but increases as its size
MBEDTLS_SSL_IN_CONTENT_LEN decreases.
* Fix check of certificate key usage in TLS 1.3. The usage of the public key
provided by a client or server certificate for authentication was not
checked properly when validating the certificate. This could cause a
client or server to be able to authenticate itself through a certificate
to an Mbed TLS TLS 1.3 server or client while it does not own a proper
certificate to do so.
Bugfix
* Declare or use PSA_WANT_ALG_CCM_STAR_NO_TAG following the general
pattern for PSA_WANT_xxx symbols. Previously you had to specify
PSA_WANT_ALG_CCM for PSA_ALG_CCM_STAR_NO_TAG.
* Fix a memory leak if mbedtls_ssl_config_defaults() is called twice.
* Fixed swap of client and server random bytes when exporting them alongside
TLS 1.3 handshake and application traffic secret.
* Fix several bugs (warnings, compiler and linker errors, test failures)
in reduced configurations when MBEDTLS_USE_PSA_CRYPTO is enabled.
* Fix a bug in (D)TLS curve negotiation: when MBEDTLS_USE_PSA_CRYPTO was
enabled and an ECDHE-ECDSA or ECDHE-RSA key exchange was used, the
client would fail to check that the curve selected by the server for
ECDHE was indeed one that was offered. As a result, the client would
accept any curve that it supported, even if that curve was not allowed
according to its configuration. Fixes #5291.
* The TLS 1.3 implementation is now compatible with the
MBEDTLS_USE_PSA_CRYPTO configuration option.
* Fix unit tests that used 0 as the file UID. This failed on some
implementations of PSA ITS. Fixes #3838.
* Fix mbedtls_ssl_get_version() not reporting TLSv1.3. Fixes #5406.
* Fix API violation in mbedtls_md_process() test by adding a call to
mbedtls_md_starts(). Fixes #2227.
* Fix compile errors when MBEDTLS_HAVE_TIME is not defined. Add tests
to catch bad uses of time.h.
* Fix a race condition in out-of-source builds with CMake when generated data
files are already present. Fixes #5374.
* Fix the library search path when building a shared library with CMake
on Windows.
* Fix bug in the alert sending function mbedtls_ssl_send_alert_message()
potentially leading to corrupted alert messages being sent in case
the function needs to be re-called after initially returning
MBEDTLS_SSL_WANT_WRITE. Fixes #1916.
* In configurations with MBEDTLS_SSL_DTLS_CONNECTION_ID enabled but not
MBEDTLS_DEBUG_C, DTLS handshakes using CID would crash due to a null
pointer dereference. Fix this. Fixes #3998.
The fix was released, but not announced, in Mbed TLS 3.1.0.
* Fix incorrect documentation of mbedtls_x509_crt_profile. The previous
documentation stated that the `allowed_pks` field applies to signatures
only, but in fact it does apply to the public key type of the end entity
certificate, too. Fixes #1992.
* Fix undefined behavior in mbedtls_asn1_find_named_data(), where val is
not NULL and val_len is zero.
* Fix compilation error with mingw32. Fixed by Cameron Cawley in #4211.
* Fix compilation error when using C++ Builder on Windows. Reported by
Miroslav Mastny in #4015.
* psa_raw_key_agreement() now returns PSA_ERROR_BUFFER_TOO_SMALL when
applicable. Fixes #5735.
* Fix a bug in the x25519 example program where the removal of
MBEDTLS_ECDH_LEGACY_CONTEXT caused the program not to run. Fixes #4901 and
#3191.
* Fix a TLS 1.3 handshake failure when the peer Finished message has not
been received yet when we first try to fetch it.
* Encode X.509 dates before 1/1/2000 as UTCTime rather than
GeneralizedTime. Fixes #5465.
* Add mbedtls_x509_dn_get_next function to return the next relative DN in
an X509 name, to allow walking the name list. Fixes #5431.
* Fix order value of curve x448.
* Fix string representation of DNs when outputting values containing commas
and other special characters, conforming to RFC 1779. Fixes #769.
* Silence a warning from GCC 12 in the selftest program. Fixes #5974.
* Fix check_config.h to check that we have MBEDTLS_SSL_KEEP_PEER_CERTIFICATE
when MBEDTLS_SSL_PROTO_TLS1_3 is specified, and make this and other
dependencies explicit in the documentation. Fixes #5610.
* Fix mbedtls_asn1_write_mpi() writing an incorrect encoding of 0.
* Fix a TLS 1.3 handshake failure when the first attempt to send the client
Finished message on the network cannot be satisfied. Fixes #5499.
* Fix resource leaks in mbedtls_pk_parse_public_key() in low
memory conditions.
* Fix server connection identifier setting for outgoing encrypted records
on DTLS 1.2 session resumption. After DTLS 1.2 session resumption with
connection identifier, the Mbed TLS client now properly sends the server
connection identifier in encrypted record headers. Fix #5872.
* Fix a null pointer dereference when performing some operations on zero
represented with 0 limbs (specifically mbedtls_mpi_mod_int() dividing
by 2, and mbedtls_mpi_write_string() in base 2).
* Fix record sizes larger than 16384 being sometimes accepted despite being
non-compliant. This could not lead to a buffer overflow. In particular,
application data size was already checked correctly.
* Fix MBEDTLS_SVC_KEY_ID_GET_KEY_ID() and MBEDTLS_SVC_KEY_ID_GET_OWNER_ID()
which have been broken, resulting in compilation errors, since Mbed TLS
3.0.
* Ensure that TLS 1.2 ciphersuite/certificate and key selection takes into
account not just the type of the key (RSA vs EC) but also what it can
actually do. Resolves #5831.
* Fix CMake windows host detection, especially when cross compiling.
* Fix an error in make where the absence of a generated file caused
make to break on a clean checkout. Fixes #5340.
* Work around an MSVC ARM64 compiler bug causing incorrect behaviour
in mbedtls_mpi_exp_mod(). Reported by Tautvydas Žilys in #5467.
* Removed the prompt to exit from all windows build programs that was causing
issues in CI/CD environments.
Changes
* The file library/psa_crypto_driver_wrappers.c is now generated
from a template. In the future, the generation will support
driver descriptions. For the time being, to customize this file,
see docs/proposed/psa-driver-wrappers-codegen-migration-guide.md
* Return PSA_ERROR_INVALID_ARGUMENT if the algorithm passed to one-shot
AEAD functions is not an AEAD algorithm. This aligns them with the
multipart functions, and the PSA Crypto API 1.1 specification.
* In mbedtls_pk_parse_key(), if no password is provided, don't allocate a
temporary variable on the heap. Suggested by Sergey Kanatov in #5304.
* Assume source files are in UTF-8 when using MSVC with CMake.
* Fix runtime library install location when building with CMake and MinGW.
DLLs are now installed in the bin directory instead of lib.
* cmake: Use GnuInstallDirs to customize install directories
Replace custom LIB_INSTALL_DIR variable with standard CMAKE_INSTALL_LIBDIR
variable. For backward compatibility, set CMAKE_INSTALL_LIBDIR if
LIB_INSTALL_DIR is set.
* Add a CMake option that enables static linking of the runtime library
in Microsoft Visual C++ compiler. Contributed by Microplankton.
* In CMake builds, add aliases for libraries so that the normal MbedTLS::*
targets work when MbedTLS is built as a subdirectory. This allows the
use of FetchContent, as requested in #5688.

Bugfix
* Fix a TLS 1.3 handshake failure when the first attempt to send the client
Finished message on the network cannot be satisfied. Fixes #5499.
Features
* Add support for authentication of TLS 1.3 clients by TLS 1.3 servers.
* Add support for server HelloRetryRequest message. The TLS 1.3 client is
now capable of negotiating another shared secret if the one sent in its
first ClientHello was not suitable to the server.
* Add support for client-side TLS version negotiation. If both TLS 1.2 and
TLS 1.3 protocols are enabled in the build of Mbed TLS, the TLS client now
negotiates TLS 1.3 or TLS 1.2 with TLS servers.
* Enable building of Mbed TLS with TLS 1.3 protocol support but without TLS
1.2 protocol support.
* Mbed TLS provides an implementation of a TLS 1.3 server (ephemeral key
establishment only). See docs/architecture/tls13-support.md for a
description of the support. The MBEDTLS_SSL_PROTO_TLS1_3 and
MBEDTLS_SSL_SRV_C configuration options control this.

* The function mbedtls_pk_setup_opaque() now supports RSA key pairs as well.
Opaque keys can now be used everywhere a private key is expected in the
TLS and X.509 modules.
* Opaque pre-shared keys for TLS, provisioned with
mbedtls_ssl_conf_psk_opaque() or mbedtls_ssl_set_hs_psk_opaque(), which
previously only worked for "pure" PSK key exchange, now can also be used
