Paul Bakker 9e36f0475f SHA2 renamed to SHA256, SHA4 renamed to SHA512 and functions accordingly
The SHA4 name was not clear with regards to the new SHA-3 standard. So
SHA2 and SHA4 have been renamed to better represent what they are:
SHA256 and SHA512 modules.

Paul Bakker 38b50d73a1 Moved PKCS#12 PBE functions to cipher / md layer where possible

Paul Bakker 28144decef PKCS#5 v2 PBES2 support and use in PKCS#8 encrypted certificates
The error code POLARSSL_ERR_X509_PASSWORD_MISMATCH is now properly
returned in case of an encryption failure in the padding. The
POLARSSL_ERR_X509_PASSWORD_REQUIRED error code is only returned for PEM
formatted private keys as for DER formatted ones it is impossible to
distinguish if a DER blob is PKCS#8 encrypted or not.

Paul Bakker 00b2860e8d pem_read_buffer() already update use_len after header and footer are read
After header and footer are read, pem_read_buffer() is able to determine
the length of input data used. This allows calling functions to skip
this PEM bit if an error occurs during its parsing.

Paul Bakker 2a84424a35 Disabled the HAVEGE random generator by default
Rationale: The HAVEGE random generator has too many caveats to be a
standard generator that people rely on. The HAVEGE random generator is not
suitable for virtualized environments. In addition the HAVEGE random
generator is dependent on timing and specific processor traits that
cannot be guaranteed by default on compile time.

Our advice: only use HAVEGE as an additional random source for your
entropy pool, never as your primary source.

Paul Bakker 8f4ddaeea9 Ability to specify allowed ciphersuites based on the protocol version.
The ciphersuites parameter in the ssl_session structure changed from
'int *' to 'int *[4]'.

The new function ssl_set_ciphersuite_for_version() sets specific entries
inside this array. ssl_set_ciphersuite() sets all entries to the same
value.

Paul Bakker d5c2b542cc Indication of x509_get_numeric_string() deprecation 2013-04-07 22:34:26 +02:00
Paul Bakker c70b982056 OID functionality moved to a separate module.
A new OID module has been created that contains the main OID searching
functionality based on type-dependent arrays. A base type is used to
contain the basic values (oid_descriptor_t) and that type is extended to
contain type specific information (like a pk_alg_t).

As a result the rsa sign and verify function prototypes have changed. They
now expect a md_type_t identifier instead of the removed RSA_SIG_XXX
defines.

All OID definitions have been moved to oid.h
All OID matching code is in the OID module.

The RSA PKCS#1 functions cleaned up as a result and adapted to use the
MD layer.

The SSL layer cleanup up as a result and adapted to use the MD layer.

The X509 parser cleaned up and matches OIDs in certificates with new
module and adapted to use the MD layer.

The X509 writer cleaned up and adapted to use the MD layer.

Apps and tests modified accordingly

Paul Bakker 1bd3ae826c Added md_process() to MD layer for generic internal access to hash
process functions

Access to process functions is needed to reduce possible timing attacks
on SSL MAC checks. As SSL is set to move to using the dynamic MD layer,
the MD layer needs access to these process functions as well.

Paul Bakker e81beda60f The SSL session cache module (ssl_cache) now also retains peer_cert information (not the entire chain)
The real peer certificate is copied into a x509_buf in the
ssl_cache_entry and reinstated upon cache retrieval. The information
about the rest of the certificate chain is lost in the process.

As the handshake (and certificate verification) has already been
performed, no issue is foreseen.

Paul Bakker 78a8c71993 Re-added support for parsing and handling SSLv2 Client Hello messages
If the define POLARSSL_SSL_SRV_SUPPORT_SSLV2_CLIENT_HELLO is enabled,

It has been updated to deny SSLv2 Client Hello messages during
renegotiation.

rsa_rsassa_pkcs1_v15_sign()

Paul Bakker 40865c8e5d Added sending of alert messages in case of decryption failures as per RFC
The flag POLARSSL_SSL_ALERT_MESSAGES switched between enabling and

other parties if they are disabled, but debugging of issues might be
harder.

Paul Bakker d66f070d49 Disable debug messages that can introduce a timing side channel.
