* Fixes #4683 -- fixed linux kernel version that has getrandom (#4684)Alex Gaynor2019-01-122-2/+2
|
* Add bindings to get SRTP protection profile (#4679)Jeremy Lainé2019-01-111-0/+6
| | | | | This adds the ability to retrieve the selected SRTP protection profile after the DTLS handshake completes. This is needed to perform the correct key derivation if multiple profiles were offered.

* OCSP bindings (#4449)Paul Kehrer2018-09-012-0/+97
| | | | | | | | | | | | | | | * add many OCSP bindings Much of OCSP was opaqued in 1.1.0 so this also adds a bunch of getters for older OpenSSL. However, 1.1.0 itself made it impossible to access certain fields in the opaque struct, so we're forced to de-opaque them for 1.1.0 through 1.1.0i as well as 1.1.1-pre1 through 1.1.1-pre9. There is a patch (openssl/openssl#7082) that fixes this and should be in 1.1.0j and 1.1.1-pre10 (or 1.1.1 final, whichever they choose to issue) * backslashes are sometimes useful * comments

* Add more SSL_CIPHER_* functions, necessary to implement ctx.get_ciphers() in ↵Amaury Forgeot d'Arc2018-07-231-0/+19
| | | | | | | | | | | | | | | | PyPy (#4364) * Add more SSL_CIPHER_* functions, necessary to implement ctx.get_ciphers() added by Python 3.6.1. * Add placeholders for other versions * Remove parameter names * LibreSSL 2.7 has the new functions * Add entries in _conditional.py * SSL_CIPHER_get_id returns int, not char*

* Make our locking setup function compy with our style guide (#4316)Alex Gaynor2018-07-061-2/+2
| | | And not expose an unprefixed name to anyone who dlopens us.
* set an OPENSSL_API_COMPAT level (#4313)Paul Kehrer2018-07-061-0/+5
| | | | | | | | | * set an OPENSSL_API_COMPAT level this helps prevent adding deprecated functions and will let us see what we need to/can prune in the distant future when we support only 1.1.0+ * raise the api compat to 1.0.1 (which doesn't matter but is less confusing)
* Revert the const bits of #4220. (#4276)David Benjamin2018-06-291-1/+1
| | | | | | | | | | | | | | | | In #4220, I switched BIO_new to take a const pointer (true in 1.1.0, but not 1.0.2) on grounds that: This also folds in the const bits from 1.1.0, on the assumption that, now that the function pointer check is gone, it will just cause cffi to generate more conservative pointer types that work for 1.0.2 as well. But I got this backwards. If the bindings say BIO_METHOD*, cffi will pass a BIO_METHOD* to BIO_new, which works in both OpenSSL versions. If it says const BIO_METHOD*, cffi will pass const BIO_METHD* to BIO_new, which does not work in 1.0.2. (Although cryptography.io's build ignores all these warnings anyway, so it's kind of moot.)
* Exposed OpenSSL prime methods (#4292)Quinten Stokkink2018-06-221-0/+6

* Cleanup unused err bindings. (#4246)David Benjamin2018-05-151-106/+0
| | | | | | | | | | | | | | | | | | | | | | | This removes: - ERR_get_state which really shouldn't be public API. - A bunch of functions that are really mostly useful within the library to add new errors. NB: I say mostly because they are also useful when trying to register a new error library, as osrandom does, but osrandom is written in C. Python code is more likely to be consuming errors. - All function codes but EVP_F_EVP_ENCRYPTFINAL_EX because tests still reference it. Per PR #3609, function codes are kind of unstable. This finishes that up and cleans up the bindings. - The "line" versions of querying the error queue, just because no one seems to be using them and there's a lot. - Error-printing functions, which make less sense in Python since you'd probably wrap in an exception. Error codes probably could also do with cleaning, but I've left them alone for now.
* Remove ECDSA_sign_setup and *sign_ex bindings. (#4245)David Benjamin2018-05-151-5/+0
| | | | | | | | | | | They are unused. These functions have two purposes. They can be used to pass your own value of k, or to amoritize the cost of generating k. Messing up k is catastrophic to ECDSA, so best not to expose that one. ECDSA signing is also quite fast, so there isn't much point in the latter. (The API comes from DSA, which is a bit slower.) Moreover, ECDSA_sign is not the same as ECDSA_sign_setup + ECDSA_sign_ex. OpenSSL has some nonce hardening features that have to get skipped when doing this.
* Remove some unused RSA bindings. (#4243)David Benjamin2018-05-141-11/+0
| | | | | | RSA_blinding_off is a silly function. RSA_SSLV23_PADDING and RSA_X931_PADDING are obsolete. The low-level padding functions appear unused and the EVP_PKEY stuff is probably a bit nicer than expecting callers to RSA_NO_PADDING and do the padding by hand.
* Remove some unused RAND bindings. (#4239)David Benjamin2018-05-141-4/+0
| | | These are unused. (And not especially useful.)
* Clean up unused EC bindings. (#4225)David Benjamin2018-05-141-79/+0
| | | | | | | | | | | | | | | | | | | | | | | * Clean up unused EC bindings. A lot of these are really OpenSSL internals, like the EC_METHOD business, support for custom curves which are a bad idea, and weird non-standard serializations like taking the usual point serialization and treating it as a single BIGNUM. I also didn't remove things when they're arguably part of a set. E.g. EC_POINT_add is used, but EC_POINT_dbl isn't. However, they both set at the same abstraction level (basic point operations), so it's strange to have one without the other. I also kept EC_POINT_is_on_curve because, although it is not used, OpenSSL prior to 1.1.0 doesn't perform this important check in EC_POINT_set_affine_coordinates_GFp (though it does in some of the functions which ultimately call it, like EC_KEY_set_public_key_affine_coordinates, what cryptography.io actually uses), so one should not expose the latter without the former. * Fix build issue.
* Remove unused BIO bindings. (#4220)David Benjamin2018-05-141-107/+3
| | | | | | | | | | | | | * Remove unused BIO bindings. This also folds in the const bits from 1.1.0, on the assumption that, now that the function pointer check is gone, it will just cause cffi to generate more conservative pointer types that work for 1.0.2 as well. * Restore some functions used externally. Datagram BIO_CTRL_* constants are intentionally omitted per discussion on the PR.
* Fix some callback type signatures. (#4227)David Benjamin2018-05-121-3/+3
