Lufi：一个支持E2E加密的文件上传工具

Lufi是一个支持E2E加密的文件上传工具，用户上传的所有文件都由浏览器进行加密，Lufi的实例管理员也无法得知你上传的是什么文件。

下面在Debian10上安装一下：

apt -y update
apt -y install build-essential libssl-dev libio-socket-ssl-perl liblwp-protocol-https-perl nginx python-certbot-nginx git

安装Carton：
cpan Carton
程序支持SQLite/MySQL/PostgreSQL作为数据库，这里直接使用SQLite，所以就不需要安装其他的依赖了。

拉取源码/复制一份配置文件/给予正确的权限/：

git clone https://framagit.org/fiat-tux/hat-softwares/lufi
cp lufi/lufi.conf.template lufi/lufi.conf
chown -R www-data:www-data lufi
cd lufi

安装/编辑配置文件：
carton install --deployment --without=test --without=postgresql --without=mysql --without=ldap --without=htpasswd
nano lufi.conf
至少取消下面贴出来的注释，还有很多其他的配置可以自己根据配置文件里的说明更改：

新建systemd服务文件：
nano /etc/systemd/system/lufi.service
写入如下内容：
[Unit]
Description=File hosting service with encryption
Documentation=https://framagit.org/luc/lufi
Requires=network.target
After=network.target

[Service]
Type=forking
User=www-data
RemainAfterExit=yes
WorkingDirectory=/opt/lufi/
PIDFile=/opt/lufi/script/hypnotoad.pid
ExecStart=/usr/local/bin/carton exec hypnotoad script/lufi
ExecStop=/usr/local/bin/carton exec hypnotoad -s script/lufi
ExecReload=/usr/local/bin/carton exec hypnotoad script/lufi

[Install]
WantedBy=multi-user.target

启动/设置开机启动：
systemctl start lufi
systemctl enable lufi nginx.service

新建一个nginx站点配置文件：
nano /etc/nginx/conf.d/lufi.conf
写入如下内容：

server {
    listen 80;

    # Adapt this to your domain!
    server_name yourdomain.com;

    location / {
        # Add cache for static files
        if ($request_uri ~* ^/(img|css|font|js)/) {
            add_header Expires "Thu, 31 Dec 2037 23:55:55 GMT";
            add_header Cache-Control "public, max-age=315360000";
        }
        # HTTPS only header, improves security
        #add_header Strict-Transport-Security "max-age=15768000";
        # Adapt this to your configuration (port, subdirectory (see below))
        proxy_pass  http://127.0.0.1:8081;
        # Really important! Lufi uses WebSocket, it won't work without this
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_http_version 1.1;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        # If you want to log the remote port of the file senders, you'll need that
        proxy_set_header X-Remote-Port $remote_port;
        proxy_set_header X-Forwarded-Proto $scheme;
        # We expect the downstream servers to redirect to the right hostname, so don't do any rewrites here.
        proxy_redirect     off;
    }
}

检查你的nginx配置有没有错误：
nginx -t

没有问题的话使用certbot签发一个ssl证书：
certbot --nginx --agree-tos --no-eff-email --email xxxxx@qq.com

打开你的域名应该可以访问到程序界面了.
上传的文件如果要下载必须先解密.
而服务器内存储的数据是加密的，管理员也看不见你上传的文件具体内容.
