i use binary mode and of course, i always set the attributes to 755
in the openpli image which is now on my STB
(openpli-7.0-release-osmini-20190422_usb.zip)
there is no libcrypto.so file in the directory libs at all !
only file which sounds a litlebit like it is libcrypt-2.25.so
Anyway , i use now oscam , it works and its OK for me.
Thanks for your help.
