+ *) Squeeze another 10% out of IGE mode when in != out.
+ [Ben Laurie]
+
+ *) AES IGE mode speedup.
+ [Dean Gaudet (Google)]
+
+ *) Add the Korean symmetric 128-bit cipher SEED (see
+ http://www.kisa.or.kr/kisa/seed/jsp/seed_eng.jsp) and
+ add SEED ciphersuites from RFC 4162:
+
+ TLS_RSA_WITH_SEED_CBC_SHA = "SEED-SHA"
+ TLS_DHE_DSS_WITH_SEED_CBC_SHA = "DHE-DSS-SEED-SHA"
+ TLS_DHE_RSA_WITH_SEED_CBC_SHA = "DHE-RSA-SEED-SHA"
+ TLS_DH_anon_WITH_SEED_CBC_SHA = "ADH-SEED-SHA"
+
+ To minimize changes between patchlevels in the OpenSSL 0.9.8
+ series, SEED remains excluded from compilation unless OpenSSL
+ is configured with 'enable-seed'.
+ [KISA, Bodo Moeller]
+
+ *) Mitigate branch prediction attacks, which can be practical if a
+ single processor is shared, allowing a spy process to extract
+ information. For detailed background information, see
+ http://eprint.iacr.org/2007/039 (O. Aciicmez, S. Gueron,
+ J.-P. Seifert, "New Branch Prediction Vulnerabilities in OpenSSL
+ and Necessary Software Countermeasures"). The core of the change
+ are new versions BN_div_no_branch() and
+ BN_mod_inverse_no_branch() of BN_div() and BN_mod_inverse(),
+ respectively, which are slower, but avoid the security-relevant
+ conditional branches. These are automatically called by BN_div()
+ and BN_mod_inverse() if the flag BN_FLG_CONSTTIME is set for one
+ of the input BIGNUMs. Also, BN_is_bit_set() has been changed to
+ remove a conditional branch.
+
+ BN_FLG_CONSTTIME is the new name for the previous
+ BN_FLG_EXP_CONSTTIME flag, since it now affects more than just
+ modular exponentiation. (Since OpenSSL 0.9.7h, setting this flag
+ in the exponent causes BN_mod_exp_mont() to use the alternative
+ implementation in BN_mod_exp_mont_consttime().) The old name
+ remains as a deprecated alias.
+
+ Similary, RSA_FLAG_NO_EXP_CONSTTIME is replaced by a more general
+ RSA_FLAG_NO_CONSTTIME flag since the RSA implementation now uses
+ constant-time implementations for more than just exponentiation.
+ Here too the old name is kept as a deprecated alias.
+
+ BN_BLINDING_new() will now use BN_dup() for the modulus so that
+ the BN_BLINDING structure gets an independent copy of the
+ modulus. This means that the previous "BIGNUM *m" argument to
+ BN_BLINDING_new() and to BN_BLINDING_create_param() now
+ essentially becomes "const BIGNUM *m", although we can't actually
+ change this in the header file before 0.9.9. It allows
+ RSA_setup_blinding() to use BN_with_flags() on the modulus to
+ enable BN_FLG_CONSTTIME.

external cache for different purposes). Previously,
