openssl/apps/pkcs12.c
Dr. Stephen Henson 647ac8d3d7 Support broken PKCS#12 key generation. 
OpenSSL versions before 1.1.0 didn't convert non-ASCII
UTF8 PKCS#12 passwords to Unicode correctly.

To correctly decrypt older files, if MAC verification fails
with the supplied password attempt to use the broken format
which is compatible with earlier versions of OpenSSL.
