@ -47,12 +47,25 @@ API Changes
purpose or CRT and/or blinding.
* The configuration option MBEDTLS_RSA_ALT can be used to define alternative
implementations of the RSA interface declared in rsa.h.
* The following functions in the message digest modules (MD2, MD4, MD5,
SHA1, SHA256, SHA512) have been deprecated and replaced as shown below.
The new functions change the return type from void to int to allow
returning error codes when using MBEDTLS_<MODULE>_ALT.
mbedtls_<MODULE>_starts() -> mbedtls_<MODULE>_starts_ret()
mbedtls_<MODULE>_update() -> mbedtls_<MODULE>_update_ret()
mbedtls_<MODULE>_finish() -> mbedtls_<MODULE>_finish_ret()
mbedtls_<MODULE>_process() -> mbedtls_internal_<MODULE>_process()
New deprecations
* Deprecate usage of RSA primitives with non-matching key-type
(e.g., signing with a public key).
* Direct manipulation of structure fields of RSA contexts is deprecated.
Users are advised to use the extended RSA API instead.
* Deprecate usage of message digest functions that return void
(mbedtls_<MODULE>_starts, mbedtls_<MODULE>_update,
mbedtls_<MODULE>_finish and mbedtls_<MODULE>_process where <MODULE> is
any of MD2, MD4, MD5, SHA1, SHA256, SHA512) in favor of functions
that can return an error code.
Bugfix
* Fix ssl_parse_record_header() to silently discard invalid DTLS records
@ -109,6 +122,13 @@ Bugfix
* Fix bug in cipher decryption with MBEDTLS_PADDING_ONE_AND_ZEROS that
sometimes accepted invalid padding. (Not used in TLS.) Found and fixed
by Micha Kraus.
* Fix the entropy.c module to not call mbedtls_sha256_starts() or
mbedtls_sha512_starts() in the mbedtls_entropy_init() function.
* Fix the entropy.c module to ensure that mbedtls_sha256_init() or
mbedtls_sha512_init() is called before operating on the relevant context
structure. Do not assume that zeroizing a context is a correct way to
reset it. Found independently by ccli8 on Github.
* In mbedtls_entropy_free(), properly free the message digest context.
Changes
* Extend cert_write example program by options to set the CRT version
@ -122,6 +142,10 @@ Changes
* Tighten the RSA PKCS#1 v1.5 signature verification code and remove the
undeclared dependency of the RSA module on the ASN.1 module.
* Add mechanism to provide alternative implementation of the DHM module.
* Update all internal usage of deprecated message digest functions to the
new ones with return codes. In particular, this modifies the
mbedtls_md_info_t structure. Propagate errors from these functions
everywhere except some locations in the ssl_tls.c module.
