Hey,
An awesome feature I'll be surely find useful is the option to remove the signature blob out a binary.
I found this project https://github.com/steakknife/unsign which claims to provide the good, but trying to re-sign a binary just messes everything up. Looks like the "unsign" does not corrects mach-o 's offsets correctly.
And an even better feature to add can be to take a binary, override its entitlements with a user-given ones, and resign the binary.
Unless there is something out there that does that already, and does that good enough.
Thanks!
