Multiple Handshake in a file.

I have a question about Hashcat,

If i have a cap file with multiple handshake,
Its possible to launch a tread of hashcat wich will try one per one to found the password ?

For example :
wpa.cap -> contain 5 handshake,
used tool cap2hccapx to convert the .cap file to a .cap2hccapx without option.
And launch a Hashcat thread with this .cap2hccapx.
Hashcat will try all handshake ?  or just the first ?

And, how its possible to open a cap2hccapx file ? for see what is content.

Thanks alot !
hashcat will try to crack all handshakes if you concatenate them into a single file.

It's a binary format and documented here:
