[PGP Disk] Help with best syntax to brute force this virtual encrypted disk?

[Snoopy]

I've got a 15 years old PGP Disk file and hell I cannot remember its password anymore...

All I remember is I used a 4096 bit encrypted password for it so please what would be the correct syntax for hascat to brute force it?

pgp virtual disk is not supported by hashcat, see examples for supported attacks, john the ripper seems to support it
