OpenSSL CHANGES
_______________
- Changes between 0.9.7f and 0.9.8 [xx XXX xxxx]
+ Changes between 0.9.8 and 0.9.9 [xx XXX xxxx]
+
+ *)
+
+ Changes between 0.9.7h and 0.9.8 [xx XXX xxxx]
+
+ *) Add attribute functions to EVP_PKEY structure. Modify
+ PKCS12_create() to recognize a CSP name attribute and
+ use it. Make -CSP option work again in pkcs12 utility.
+ [Steve Henson]
+
+ *) Add new functionality to the bn blinding code:
+ - automatic re-creation of the BN_BLINDING parameters after
+ a fixed number of uses (currently 32)
+ - add new function for parameter creation
+ - introduce flags to control the update behaviour of the
+ BN_BLINDING parameters
+ - hide BN_BLINDING structure
+ Add a second BN_BLINDING slot to the RSA structure to improve
+ performance when a single RSA object is shared among several
+ threads.
+ [Nils Larsch]
+
+ *) Add support for DTLS.
+ [Nagendra Modadugu <nagendra@cs.stanford.edu> and Ben Laurie]
*) Add support for DER encoded private keys (SSL_FILETYPE_ASN1)
to SSL_CTX_use_PrivateKey_file() and SSL_use_PrivateKey_file()
Makefile.shared, for Cygwin's sake.
[Richard Levitte]
- *) Extend the BIGNUM API by creating new macros that behave like
- functions
-
- void BN_set_sign(BIGNUM *a, int neg);
- int BN_get_sign(const BIGNUM *a);
+ *) Extend the BIGNUM API by creating a function
+ void BN_set_negative(BIGNUM *a, int neg);
+ and a macro that behave like
+ int BN_is_negative(const BIGNUM *a);
- and avoid the need to access 'a->neg' directly in applications.
- [Nils Larsch <nla@trustcenter.de>]
+ to avoid the need to access 'a->neg' directly in applications.
+ [Nils Larsch]
*) Implement fast modular reduction for pseudo-Mersenne primes
used in NIST curves (crypto/bn/bn_nist.c, crypto/ec/ecp_nist.c).
*) Include some named elliptic curves, and add OIDs from X9.62,
SECG, and WAP/WTLS. Each curve can be obtained from the new
function
- EC_GROUP_new_by_nid(),
+ EC_GROUP_new_by_curve_name(),
and the list of available named curves can be obtained with
EC_get_builtin_curves().
Also add a 'curve_name' member to EC_GROUP objects, which can be
accessed via
- EC_GROUP_set_nid()
- EC_GROUP_get_nid()
- [Nils Larsch <nla@trustcenter.de, Bodo Moeller]
+ EC_GROUP_set_curve_name()
+ EC_GROUP_get_curve_name()
+ [Nils Larsch <larsch@trustcenter.de, Bodo Moeller]
*) Remove a few calls to bn_wexpand() in BN_sqr() (the one in there
was actually never needed) and in BN_mul(). The removal in BN_mul()
differing sizes.
[Richard Levitte]
- Changes between 0.9.7f and 0.9.7g [XX xxx xxxx]
+ Changes between 0.9.7g and 0.9.7h [XX xxx XXXX]
+
+ *) Make a new fixed-window mod_exp implementation the default for
+ RSA, DSA, and DH private-key operations so that the sequence of
+ squares and multiplies and the memory access pattern are
+ independent of the particular secret key. This will mitigate
+ cache-timing and potential related attacks.
+
+ BN_mod_exp_mont_consttime() is the new exponentiation implementation,
+ and this is automatically used by BN_mod_exp_mont() if the new flag
+ BN_FLG_EXP_CONSTTIME is set for the exponent. RSA, DSA, and DH
+ will use this BN flag for private exponents unless the flag
+ RSA_FLAG_NO_EXP_CONSTTIME, DSA_FLAG_NO_EXP_CONSTTIME, or
+ DH_FLAG_NO_EXP_CONSTTIME, respectively, is set.
+
+ [Matthew D Wood (Intel Corp), with some changes by Bodo Moeller]
+
+ *) Change the client implementation for SSLv23_method() and
+ SSLv23_client_method() so that is uses the SSL 3.0/TLS 1.0
+ Client Hello message format if the SSL_OP_NO_SSLv2 option is set.
+ (Previously, the SSL 2.0 backwards compatible Client Hello
+ message format would be used even with SSL_OP_NO_SSLv2.)
+ [Bodo Moeller]
+
+ *) Add support for smime-type MIME parameter in S/MIME messages which some
+ clients need.
+ [Steve Henson]
+
+ *) New function BN_MONT_CTX_set_locked() to set montgomery parameters in
+ a threadsafe manner. Modify rsa code to use new function and add calls
+ to dsa and dh code (which had race conditions before).
+ [Steve Henson]
+
+ *) Include the fixed error library code in the C error file definitions
+ instead of fixing them up at runtime. This keeps the error code
+ structures constant.
+ [Steve Henson]
+
+ Changes between 0.9.7f and 0.9.7g [11 Apr 2005]
+
+ *) Fixes for newer kerberos headers. NB: the casts are needed because
+ the 'length' field is signed on one version and unsigned on another
+ with no (?) obvious way to tell the difference, without these VC++
+ complains. Also the "definition" of FAR (blank) is no longer included
+ nor is the error ENOMEM. KRB5_PRIVATE has to be set to 1 to pick up
+ some needed definitions.
+ [Steve Henson]
*) Undo Cygwin change.
