2013-07-03 17:22:32 +02:00
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 5dc6b5fb05 Made supported curves configurable 2013-06-29 23:26:34 +02:00
Paul Bakker 2fbefde1d8 Client and server now filter sent and accepted ciphersuites on minimum
and maximum protocol version
2013-06-29 18:35:40 +02:00
Paul Bakker 59c28a2723 SSL v2 handshake should also handle dynamic ciphersuites 2013-06-29 18:35:40 +02:00
Paul Bakker b6c5d2e1a6 Cleanup up non-prototyped functions (static) and const-correctness
More fixes based on the compiler directives -Wcast-qual -Wwrite-strings
-Wmissing-prototypes -Wmissing-declarations. Not everything with regards
to -Wcast-qual has been fixed as some have unwanted consequences for the
rest of the code.

Paul Bakker 2013950545 Secure renegotiation extension should only be sent in case client supports secure renegotiation
(cherry picked from commit 7c3c3899cf)
2013-06-24 19:09:24 +02:00
Paul Bakker 48f7a5d724 DHE-PSK based ciphersuite support added and cleaner key exchange based
code selection

The base RFC 4279 DHE-PSK ciphersuites are now supported and added.

The SSL code cuts out code not relevant for defined key exchange methods
2013-04-19 20:47:26 +02:00
Paul Bakker ed27a041e4 More granular define selections within code to allow for smaller code
sizes
2013-04-18 23:12:34 +02:00
Paul Bakker fbb17804d8 Added pre-shared key handling for the server side of SSL / TLS
Server side handling of the pure PSK ciphersuites is now in the base
code.
2013-04-18 23:12:33 +02:00
Paul Bakker 70df2fbaa5 Split parts of ssl_parse_client_key_exchange() into separate functions
Made ssl_parse_client_dh_public(), ssl_parse_cient_ecdh_public() and
ssl_parse_encrypted_pms_secret() in preparation for PSK-related code
2013-04-18 23:12:33 +02:00
Paul Bakker f7abd422dc Removed extra spaces on end of lines 2013-04-16 18:09:45 +02:00
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.
(cherry picked from commit a62729888b)

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 b7149bcc90 Corrected behaviour for CBC-based suites using the SHA384 MAC and PRF 2013-03-20 15:30:09 +01:00
Paul Bakker 41c83d3f67 Added Ephemeral Elliptic Curve Diffie Hellman ciphersuites to SSL/TLS
Made all modifications to include Ephemeral Elliptic Curve Diffie
Hellman ciphersuites into the existing SSL/TLS modules. All basic
handling of the ECDHE-ciphersuites (TLS_ECDHE_RSA_WITH_NULL_SHA,
TLS_ECDHE_RSA_WITH_RC4_128_SHA, TLS_ECDHE_RSA_WITH_3DES_EDE_CBC_SHA,
TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA, TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA)
has been included.

Paul Bakker 68884e3c09 Moved to advanced ciphersuite representation and more dynamic SSL code 2013-03-13 14:48:32 +01:00
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,
the SSL Server module can handle the old SSLv2 Client Hello messages.

It has been updated to deny SSLv2 Client Hello messages during
renegotiation.
2013-03-06 18:01:03 +01:00
Paul Bakker 1961b709d8 Added ssl_handshake_step() to allow single stepping the handshake
process

Single stepping the handshake process allows for better support of
non-blocking network stacks and for getting information from specific
handshake messages if wanted.
