SSLeay was the name of the library that was subsequently turned into OpenSSL many moons ago (1999). curl does not work with the old SSLeay library since years. This is now reflected by only using USE_OPENSSL in code that depends on OpenSSL.

|
|
* 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:

|
* http://davenport.sourceforge.net/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.
