1) Certificate Message with no certs
OpenSSL implementation sends the Certificate message during SSL
handshake, however as per the specification, these have been omitted.
-- RFC 2712 --
CertificateRequest, and the ServerKeyExchange shown in Figure 1
will be omitted since authentication and the establishment of a
master secret will be done using the client's Kerberos credentials
for the TLS server. The client's certificate will be omitted for
the same reason.
-- RFC 2712 --
3) Pre-master secret Protocol version
The pre-master secret generated by OpenSSL does not have the correct
client version.
RFC 2712 says, if the Kerberos option is selected, the pre-master
secret structure is the same as that used in the RSA case.
TLS specification defines pre-master secret as:
struct {
ProtocolVersion client_version;
opaque random[46];
} PreMasterSecret;
where client_version is the latest protocol version supported by the
client
The pre-master secret generated by OpenSSL does not have the correct
client version. The implementation does not update the first 2 bytes
of random secret for Kerberos Cipher suites. At the server-end, the
client version from the pre-master secret is not validated.

- hide the EC_KEY structure definition in ec_lcl.c + add
some functions to use/access the EC_KEY fields
- change the way how method specific data (ecdsa/ecdh) is
attached to a EC_KEY
- add ECDSA_sign_ex and ECDSA_do_sign_ex functions with
additional parameters for pre-computed values
- rebuild libeay.num from 0.9.7
1. "unsigned long long" isn't portable changed: to BN_ULLONG.
2. The LL prefix isn't allowed in VC++ but it isn't needed where it is used.
2. Avoid lots of compiler warnings about signed/unsigned mismatches.
3. Include new library directory pqueue in mk1mf build system.
4. Update symbols.
functions and macros.
This change has associated tags: LEVITTE_before_const and
LEVITTE_after_const. Those will be removed when this change has been
properly reviewed.
I have tried to convert 'len' type variable declarations to unsigned as a
means to address these warnings when appropriate, but when in doubt I have
used casts in the comparisons instead. The better solution (that would get
us all lynched by API users) would be to go through and convert all the
function prototypes and structure definitions to use unsigned variables
except when signed is necessary. The proliferation of (signed) "int" for
strictly non-negative uses is unfortunate.
