d3ddf0228e Disable SHA-2 ciphersuites in < TLS 1.2 connections.
(TLS 1.2 clients could end up negotiating these with an OpenSSL server
with TLS 1.2 disabled, which is problematic.)

800e1cd969 Additional workaround for PR#2771
If OPENSSL_MAX_TLS1_2_CIPHER_LENGTH is set then limit the size of client
ciphersuites to this value. A value of 50 should be sufficient.

5863163732 Additional compatibility fix for MDC2 signature format.
Update RSA EVP_PKEY_METHOD to use the OCTET STRING form of MDC2 signature:
this will make all versions of MDC2 signature equivalent.
2012-02-15 14:27:25 +00:00
Dr. Stephen Henson
83cb7c4635 An incompatibility has always existed between the format used for RSA
signatures and MDC2 using EVP or RSA_sign. This has become more apparent
when the dgst utility in OpenSSL 1.0.0 and later switched to using the
EVP_DigestSign functions which call RSA_sign.

This means that the signature format OpenSSL 1.0.0 and later used with
dgst -sign and MDC2 is incompatible with previous versions.

Add detection in RSA_verify so either format works.

Note: MDC2 is disabled by default in OpenSSL and very rarely used in practice.

f71c6e52f7 Add support for distinct certificate chains per key type and per SSL
structure.

Before this the only way to add a custom chain was in the parent SSL_CTX
(which is shared by all key types and SSL structures) or rely on auto
chain building (which is performed on each handshake) from the trust store.

8e1dc4d7ca Support for fixed DH ciphersuites.
The cipher definitions of these ciphersuites have been around since SSLeay
but were always disabled. Now OpenSSL supports DH certificates they can be
finally enabled.

Various additional changes were needed to make them work properly: many
unused fixed DH sections of code were untested.
