/*
|
|
* Curl_des_set_odd_parity()
|
|
*
|
|
* This is used to apply odd parity to the given byte array. It is typically
|
|
* used by when a cryptography engines doesn't have it's own version.
|
|
*
|
|
* The function is a port of the Java based oddParity() function over at:
|
|
*
|
|
* https://davenport.sourceforge.io/ntlm.html
|
|
*
|
|
* Parameters:
|
|
*
|
|
* bytes [in/out] - The data whose parity bits are to be adjusted for
|
|
* odd parity.
|
|
* len [out] - The length of the data.
