problem veracrypt - device mapper

[ciccio]

hallo, i installed veracrypt 1.24 which runs ok but i get an error on mounting the crypted volume, during setup i read a message about installing fuse and dev mapper tools, i installed fuse then I tried to check with ls/dev/mapper but nothing is present... i cant find anything about installing device mapper on bsd (

[ciccio]

any ideas?

ok, reformulate in another way ... what is the default system for cryptography in BSD? How is cryptsetup in linux, so to speak ...
