Kris Kwiatkowski	e33ddfeb80	Use CPUID to get information about CPU capabilities Using golang.org/x/sys/cpu would be really great, but it makes it hard to vendor the library with go 1.10. This patch gets information about CPU capabilities directly from CPUID	vor 6 Jahren

Henry Case	2f9b10c0f0	p503 in SIDH/SIKE * Makes it possible to use p503 in SIDH and SIKE * Refactors tests so that unit tests in SIKE and SIDH are run for each prime field. It adds test data array called 'tdata' which describes test parameters for underlying prime field. When new field is added, it's enough to simply add new test data to 'tdata' vector in order to run all existing tests with new prime field. * SIKE/p503 is now tested with official test vectors from NIST submission	vor 6 Jahren

Henry Case	efe8185fab	removes P751_SecretKeySize and P751_SampleRate Those two constnts are not used anymore and can be safely removed as it is not used anymore. SidhParams struct was also modified.	vor 6 Jahren
Henry Case	e5cb7382ac	Refactor private key generation Private key generation can take advantage of the fact that keyspace for secret key is (0, 2^x - 1), for some possitivite value of 'x' (see SIKE, 1.3.8). It means that all bytes in the secret key, but the last one, can take any value between <0x00,0xFF>. Similarily for the last byte, but generation needs to chop off some bits, to make sure generated value is an element of a key-space. Assuming uniform distribution of bytes generated by RNG, secret key is still chosen uniformly at random, but there is no need to maintain field specific assembly code.	vor 6 Jahren
