cbfcaa9206 x509parse_crtpath() is now reentrant and uses more portable stat() 
Moved from readdir() to readdir_r() and use stat instead of the less
portable d_type from struct dirent.

d6d4109adc Changed x509parse_crt_der() to support adding to chain. 
Removed chain functionality from x509parse_crt() as x509parse_crt_der()
now handles that much cleaner.

4087c47043 Added mechanism to provide alternative cipher / hash implementations 
All symmetric cipher algorithms and hash algorithms now include support
for a POLARSSL_XXX_ALT flag that prevents the definition of the
algorithm context structure and all 'core' functions.

cf6e95d9a8 Parsing of PKCS#8 encrypted private key files added and PKCS#12 basis 
PKCS#8 encrypted key file support has been added to x509parse_key() with
support for some PCKS#12 PBE functions (pbeWithSHAAnd128BitRC4,
pbeWithSHAAnd3-KeyTripleDES-CBC and pbeWithSHAAnd2-KeyTripleDES-CBC)

65a1909dc6 Internally split up x509parse_key() 
Split up x509parse_key() into a (PEM) handler function and specific
DER parser functions for the PKCS#1 (x509parse_key_pkcs1_der()) and
unencrypted PKCS#8 (x509parse_key_pkcs8_unencrypted_der()) private
key formats.

1922a4e6aa ssl_parse_certificate() now calls x509parse_crt_der() directly 2013-06-06 15:11:16 +02:00

6417186365 x509parse_crt() now better handles PEM error situations 
Because of new pem_read_buffer() handling of when it writes use_len,
x509parse_crt() is able to better handle situations where a PEM blob
results in an error but the other blobs can still be parsed.
 2013-06-06 15:01:18 +02:00

9255e8300e 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.

a62729888b Ability to specify allowed ciphersuites based on the protocol version. 
The ciphersuites parameter in the ssl_session structure changed from
'int *' to 'int **' and is now malloced in ssl_init() and freed in
ssl_free().

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

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.

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.

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.

e47b34bdc8 Removed further timing differences during SSL message decryption in ssl_decrypt_buf()

has no branch prediction timing differences.

The additional MAC checks further straighten out the timing differences.

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.
