Let say if anyone visit .onion site and download a file. Can isp see the contents of file that is downloaded. is connection between pc and the entry node is encrypted or unencrypted in case i visit a .onion site cause i know that .onion sites are not https sites. Is connection between pc and entry node is secured or unsecured in case i visit a https site or http site or .onion site (in all 3 cases). Does isp can sniff between the connection of pc and the entry node.
Because onion services route their traffic entirely through the Tor network, connection to an onion service is encrypted end-to-end and not subject to eavesdropping.
