2011-12-05Fix typos in ssl_cipher.erlTuncer Ayaz
2011-10-24fix handling of block_decipher/5 failureAndreas Schultz
A wrong decryption key would cause a badmatch in generic_block_cipher_from_bin/2. The try in block_decipher/5 was probably intendend to deal with that, but was misplace for this. Additionaly, generating a failure alert erly, without computing the record MAC, creates vector for a timing attack on CBC padding (for details check TLS 1.2 RFC 5246, Sect. 6.2.3.2.). This attach vector and the counter meassure applies to all SSL/TLS versions. As a counter messure, compute the MAC even when decryption or padding checks fail. A invalid padding will force a MAC failure by intentionaly invalidating the content.
2010-11-30Fixed guard and test caseIngela Anderton Andin
Data to sign and verify should be inputed as binaries. Also cleaned up and moved some dialyzer specs.
2010-11-18Added alert in stream cipher case.Ingela Anderton Andin
Also changed alert to BAD_RECORD_MAC as: "differentiating between bad_record_mac and decryption_failed alerts may permit certain attacks against CBC mode as used in TLS [CBCATT]. It is preferable to uniformly use the bad_record_mac alert to hide the specific type of the error." Also cleaned up the code and changed a few other alert reasons in according to alert descriptions in the TLS RFC 4346. And added function terminate_alert/3 so that we can differentiate between a crash in ssl (a bug in our code) and a crash in the application using ssl.
2010-11-10Added "DECRYPTION_FAILED ALERT" for block decipher failure.Ingela Anderton Andin
Also fixed incorrect dialyzer spec.
2010-10-07Anonymous cipher suitesIngela Anderton Andin
For testing purposes ssl now also support some anonymous cipher suites when explicitly configured to do so. Also moved session cache tests to its own suite, so that timeout of end_per_testcase when the mnesia is used as session cache will not affect other test cases.
2010-08-24Merge branch 'ia/ssl-interop/OTP-8740' into devIngela Anderton Andin
* ia/ssl-interop/OTP-8740: Do not check the padding for TLS 1.0
2010-08-23Revise the public_key APIIngela Anderton Andin
Cleaned up and documented the public_key API to make it useful for general use.
2010-08-18Do not check the padding for TLS 1.0Ingela Anderton Andin
For interoperability reasons we do not check the padding in TLS 1.0 as it is not strictly required and breaks interopability with for instance Google.
2010-06-22Added more -spec definitions.Ingela Anderton Andin
2010-06-07OTP-8587 DSA key supportIngela Anderton Andin
New ssl now support client/server-certificates signed by dsa keys.
2010-05-28Added missing padding check.Ingela Anderton Andin

2010-05-21Decision not to support DH and export cipher suites.Ingela Anderton Andin
2010-05-18Commented out currently unsupported code. To be supported or removed in the ↵Ingela Anderton Andin
future.
