Jack Grigg	20abe2083c	Extend byte array expansion and compression methods with optional padding	2016-08-16 11:02:04 +12:00
Jack Grigg	caa0348f04	Update Equihash hash generation to match the Zcash spec ... Changes: - floor(512/n)*n/8 bytes of BLAKE2b output is split between floor(512/n) adjacent indices, instead of using one hash call per index. - Parameters with n/(k+1) mod 8 != 0 will expand the BLAKE2b output to byte boundaries for colliding, instead of using a longer output and clearing bits. - The genesis blocks have been regenerated. - The test vectors have been regenerated. - The Equihash inputs for the cancellation tests were modified to ensure that valid solutions were available to exercise the full solver.	2016-08-16 11:02:04 +12:00
Jack Grigg	881ffbfc87	Add methods for byte array expansion and compression ... These methods convert between: - A byte array of length NL/8, and - An array of N blocks of ceil(L/8) bytes.	2016-08-16 11:02:00 +12:00
