@ -15,6 +15,23 @@ Security
Features
* Allow comments in test data files.
API Changes
* Extend RSA interface by multiple functions allowing structure-
independent setup and export of RSA contexts. Most notably,
mbedtls_rsa_import and mbedtls_rsa_complete are introduced for setting
up RSA contexts from partial key material and having them completed to the
needs of the implementation automatically. This allows to setup private RSA
contexts from keys consisting of N,D,E only, even if P,Q are needed for the
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.
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.
Bugfix
* Fix ssl_parse_record_header() to silently discard invalid DTLS records
as recommended in RFC 6347 Section 4.1.2.7.

programs/aes/aescrypt2 and programs/aes/crypt_and_hash.
