Manuel Pégourié-Gonnard 581e6b6d6c Prepare migrating max fragment length to session
Remove max_frag_len member so that reseting session by memset()ing it to zero
does the right thing.

Paul Bakker 9e36f0475f SHA2 renamed to SHA256, SHA4 renamed to SHA512 and functions accordingly

SHA256 and SHA512 modules.

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.
2013-06-25 16:25:17 +02:00
Paul Bakker 90995b5ce3 Added mechanism to provide alternative cipher / hash implementations
All symmetric cipher algorithms and hash algorithms now include support

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 d4a56ec6bf Added pre-shared key handling for the client side of SSL / TLS

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.

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 e47b34bdc8 Removed further timing differences during SSL message decryption in ssl_decrypt_buf()
New padding checking is unbiased on correct or incorrect padding and
has no branch prediction timing differences.

The additional MAC checks further straighten out the timing differences.

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
disabling the sending of alert messages that give adversaries intel
about the result of their action. PolarSSL can still communicate with
other parties if they are disabled, but debugging of issues might be
harder.
2013-02-02 19:04:13 +01:00
Paul Bakker d66f070d49 Disable debug messages that can introduce a timing side channel.
Introduced the POLARSSL_SSL_DEBUG_ALL flag to enable all these debug
messages in case somebody does want to see the reason checks fail.

non-blocking network stacks and for getting information from specific
handshake messages if wanted.
