libnss3 usage is a bit crude and has memory leaks about firefox_decrypt

Looks nice 👍

Hi @ser2-creator thanks for the code.
Indeed the implementation is crude. Mostly on 'sorta works' basis. The weird cast was a shrug fix for a segfault (as you noticed).
Your code is much nicer so I'll look into merging this soon.

Any name I could credit you under?

I prefer not to be credited :) Just use it.

Also an option :)

For the error messages, I use the following

self._makefu(ct.c_int, "PORT_GetError")
self._makefu(ct.c_char_p, "PR_ErrorToName", ct.c_int)
self._makefu(ct.c_char_p, "PR_ErrorToString", ct.c_int, ct.c_uint32)

and

try:
	code = self._PORT_GetError()
	name = self._PR_ErrorToName(code)
	name = "NULL" if name is None else name.decode("ascii")
	text = self._PR_ErrorToString(code, 0) # 0 is the default language
	text = text.decode("utf8")
except Exception: # I guess only UnicodeDecodeError could occur
	name = "?"
	text = "error getting error message"

I am out...

Merged, thanks again.
