Did Jtool2 drop support of reading code signatures for directories? Following along with the examples in *OS Internals v3 and I get the message "Can't operate on a directory (yet...)" using version 2.0 (beta 5, LAS) compiled on Aug 12 2019 19:31:46. Jtool v1 works well with this so I was just curious for this change. Thanks

Yes; I haven't moved all jtool's code signing features to jtool2 yet - apparently this one was lost. Expect it back in when jtool2 goes official 1.0 end of month, and thanks for noticing.

jtool2 crashes when checking a signature for a plugin (appex), on Ubuntu. Same thing worked with old jtool, but there is a good chance the signature itself is invalid. Error is below

jtool2: malloc.c:2392: sysmalloc: Assertion `(old_top == initial_top (av) && old_size == 0) || ((unsigned long) (old_size) >= MINSIZE && prev_inuse (old_top) && ((unsigned long) old_end & (pagesize - 1)) == 0)' failed.
Aborted (core dumped)

If you need more input please let me know (and how to get it, since I am not really familiar with Linux)

yes, please - I need the binary so I can reproduce and figure it out.

BDA:
----
- iOS 13 friendly
- A13 chip added to chip list
- Preliminary support for iBoot images (iBoot, SecureROM) now that anyone can dump them thanks to @Axi0mX's awesome CheckM8
- -Fr will now find references to addresses in kernelcaches even if it's tagged pointers!

- Bufixes:
- Will not dump file sections which aren't mapped
