Decompress a compressed public key (x co-ord and low-bit of y-coord). @param xBN - @param yBit - @return -

Signs the given hash and returns the R and S components as BigIntegers and put them in ECDSASignature @param input to sign @return ECDSASi

@param arg - not more that 32 bits @return - bytes of the value pad with complete to 32 zeroes

Finds leaf by the id @param id0 @param id1 @return found leaf or null if not found

@param bytes The bytes to be encoded @param offset The index of the first byte to encode @param length The number of bytes to encoder @param out St

t @param r @param s @return -

Creates an ECKey that cannot be used for signing, only verifying signatures, from the given point. The compression state of pub will be preserved. @p
