cap2hccapx

Hello all,

Can someone tell me why every time I convert a cap file to hccapx cap2hccapx writes 2 or more handshakes. When intial cap file is checked with aircrack aircrack shows on 1 handshake

Please any info how to fix this as it seems to stop hashcat cracking this hash even when I put the password as the mask.

Thanks Kev
