Where/how do I view my seed in core 13.2? I understand that as of 13.0, the hd wallets are used by default.
To get the extended private masterkey itself (not a seed), you can use the
dumpwallet command and provide it with a filename to dump your keys to. The extended master key will be at the top of the file, and then it will list all addresses along with their keypaths underneath that, line by line.
Note that the dumped file is not encrypted, so be careful with what you do with it :)
