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.

Paul Bakker 37286a573b Fixed net_bind() for specified IP addresses on little endian systems 2013-03-06 18:01:03 +01:00
Paul Bakker 8804f69d46 Removed timing differences due to bad padding from RSA decrypt for 
PKCS#1 v1.5 operations
 2013-03-06 18:01:03 +01:00
Paul Bakker a43231c5a5 Added support for custom labels when using rsa_rsaes_oaep_encrypt() or rsa_rsaes_oaep_decrypt() 2013-03-06 18:01:02 +01:00
Paul Bakker b386913f8b Split up the RSA PKCS#1 encrypt, decrypt, sign and verify functions 
Split rsa_pkcs1_encrypt() into rsa_rsaes_oaep_encrypt() and
rsa_rsaes_pkcs1_v15_encrypt()
Split rsa_pkcs1_decrypt() into rsa_rsaes_oaep_decrypt() and
rsa_rsaes_pkcs1_v15_decrypt()
Split rsa_pkcs1_sign() into rsa_rsassa_pss_sign() and
rsa_rsassa_pkcs1_v15_sign()
Split rsa_pkcs1_verify() into rsa_rsassa_pss_verify() and
rsa_rsassa_pkcs1_v15_verify()

The original functions exist as generic wrappers to these functions.

Paul Bakker e3e4a59622 Added bugfix line for previous fixes for MS Visual Studio 2013-03-06 18:01:02 +01:00
Paul Bakker 3d2dc0f8e5 Corrected GCM counter incrementation to use only 32-bits instead of 128-bits 
Using 32-bits has the possibility to overwrite the IV in the first 12
bytes of the Y variable.

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 c0463502ff Fixed memory leak in ssl_free() and ssl_reset() for active session 2013-02-14 11:19:38 +01:00
Paul Bakker c7a2da437e Updated for PolarSSL 1.2.5 2013-02-02 19:23:57 +01:00
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.

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.

Paul Bakker 8fe40dcd7d Allow enabling of dummy error_strerror() to support some use-cases 
Enable a dummy error function to make use of error_strerror() in
third party libraries easier.

Disable if you run into name conflicts and want to really remove the
error_strerror()

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.
