如果没有设置主密码，Firefox 使用空密码。

有关用于解密和转储数据（以及更多）的脏 Python 脚本，请参见以下代码。这是我的一个旧项目，我刚刚更新了signons.sqlite之前（现在logins.json）保存的密码和用户名的读取。我不能保证（一切）都正常工作，但在我的测试用例中确实如此。

# Some little firefox forensic script delivering following data:
# - saved passwords (decrypted if no master pw is set)
# - visited pages
# - download history
# - form history
# - cookies 
#
# TODO:
# - flash cookies and stuff
# - finish comments
# - add little brute forcer for master pw
# - dump master pw ?
# - add some more compatibility stuff (mac if requested, else fuck it)
# - use some user defined exceptions instead plain exception
# - cache
# - think about which data from the db to return ;)

# ATTENTION: On my win7 system i needed a newer sqlite version.

解密 Firefox 保存的密码数据库的指南

1. git clone https://github.com/unode/firefox_decrypt.git
2. cd firefox_decrypt
3. python firefox_decrypt.py
4. 如果您有主密码，请输入主密码，或者直接按回车键
5. 享受

或者你也可以使用https://www.dumpzilla.org/ 👍

使用 libdb-utils（基于 rhel）或 libdb1-compat（基于 debian）包中的 db_dump185 命令

我知道这是一个老问题，但我自己一直在研究这个问题，想要一个问题的答案，而不是解决方法。

之所以如此困难，是因为这个 key3.db 文件实际上是 berkeley 数据库的旧版本，常规 db_dump 命令无法读取。为了阅读这个 1.85 版本的包，我需要使用几乎相同的 db_dump185 命令，这并不是很明显。我绕着圈子试图用 --enable-dump185 选项重新编译，而整个操作系统包都包含该选项，但需要一个单独的命令才能利用。

现在我打开了那个数据库，我仍然不确定如何处理里面的数据，这似乎与命令行工具使用 key3.db 和 logins.json 解密我的 Firefox 45.7.0 密码的问题相同？也有。我认为我目前的解决方案是不使用 (cert8|key3).db 而是改为使用 (cert9|key4).db，因为 sqlite3 似乎能够打开 key4.db 而无需大惊小怪。似乎 key4.db 中的元数据表包含 item1 和 item2 记录，我假设它们确实是加密/解密值进/出 logins.json 所需的密钥和 IV，但我仍然不确定如何在这一点上把所有这些放在一起。

希望如果我自己无法弄清楚这一点，则此信息可以帮助其他人找到我现在正在关注的当前兔子洞之后的答案。
