commit 0238eb8f3612515f4374381b593dd79116169330
|
||||

|
||||
|
||||
fix concatkdf failures on big endian architectures
|
||||
|
||||
Several of the elements used to compute the digest in ECDH-ES key
|
||||
agreement computation are represented in binary form as a 32-bit
|
||||
integer length followed by that number of octets. the length
|
||||
field. The 32-bit length integer is represented in big endian
|
||||
format (the 8 most significant bits are in the first octet.).
|
||||
|
||||
The conversion to a 4 byte big endian integer was being computed
|
||||
in a manner that only worked on little endian architectures. The
|
||||
function htonl() returns a 32-bit integer whose octet sequence given
|
||||
the address of the integer is big endian. There is no need for any
|
||||
further manipulation.
|
||||
|
||||
The existing code used bit shifting on a 32-bit value. In C bit
|
||||
shifting is endian agnostic for multi-octet values, a right shift
|
||||
moves most significant bits toward least significant bits. The result
|
||||
of a bit shift of a multi-octet value on either big or little
|
||||
archictures will always be the same provided you "view" it as the same
|
||||
data type (e.g. 32-bit integer). But indexing the octets of that
|
||||
mulit-octet value will be different depending on endianness, hence the
|
||||
assembled octets differed depending on endianness.
