Parity is apparently not checked by the EVP_Encrypt funtions. I
toggled the parity bits and encryption still worked and produced the
same result. There is a DES set_key function which checks for weak
keys and checks parity but this functionality does not seem to be
available separately. Do you think functions for setting and checking
are required or do you think one of them is sufficient?

Cheers,
Sven
