Paul Bakker fae35f0601 Functions in cipher_wrap.c marked static 2013-03-13 10:33:51 +01:00
Paul Bakker d1df02a8a3 Functions inside md_wrap.c now marked static 2013-03-13 10:31:31 +01:00
Paul Bakker ac0fba5389 Added missing header for MD2 and made code compile with missing header
files
2013-03-13 10:28:40 +01:00
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 90f042d4cb Prepared for PolarSSL 1.2.6 release 2013-03-11 11:38:44 +01:00
Paul Bakker fb1cbd3cea Fixed assembly code for ARM (Thumb and regular) for some compilers 2013-03-06 18:14:52 +01:00
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,
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 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 8ddb645ad3 Added conversion to int for a t_uint value to prevent compiler warnings
On 64-bit platforms t_uint can be larger than int resulting in compiler
warnings on some platforms (MS Visual Studio)

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 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.
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.

error_strerror()
