* add support for prehashing in ECDSA sign/verify * move signature_algorithm check to its own function
* support RSA verify with prehashing * review feedback * more dedupe * refactor and move to a separate module
* support prehashing in RSA sign * check to make sure digest size matches prehashed data provided * move doctest for prehashed
* change derive_elliptic_curve_public_point to return EllipticCurvePublicKey * also rename the backend interface method * review feedback * Rename to derive_elliptic_curve_private_key * Returns EllipticCurvePrivateKey * Reuses the EC_POINT in the openssl impl * Rename "secret" arg to "private_value" which is consistent with our naming for the value in ECPrivateNumbers.
* Raize padding block_size limit to what is allowed by the specs. * Add tests for raising padding limits. * Amend C code for padding check to use uint16_t instead of uint8_t. * Fix test to work in Python 3. * Fix typo. * Fix another typo. * Fix return type of the padding checks. * Change hypothesis test on padding. * Update comment.
* cx_freeze support for default_backend * updated tabing to spaces * corrected spacing * moved finding backend to backends __init__ * update to check to see if sys is frozen * corrected pep8 issues * update based on comments * changes to simplify, support testing, and improve comments * add changelog entry * right, coverage. I remember now. Time for some contortions. * updated with review feedback
* Add a bytes method to get the DER ASN.1 encoding of an X509 name. This is useful for creating an OpenSSL style subject_name_hash (#3011) * add to backend interface and update multibackend * bytes -> public_bytes
* Remove Python OpenSSL locking callback and replace it with one in C The Python OpenSSL locking callback is unsafe; if GC is triggered during the callback's invocation, it can result in the callback being invoked reentrantly, which can lead to deadlocks. This patch replaces it with one in C that gets built at compile time via cffi along with the rest of the OpenSSL binding. * fixes for some issues * unused * revert these changes * these two for good measure * missing param * sigh, syntax * delete tests that assumed an ability to mess with locks * style fixes * licensing stuff * utf8 * Unicode. Huh. What it isn't good for, absolutely nothing.
