MailConfigApplier and ExternalStorageConfigApplier read their settings through the `encrypted` casts -- decrypted -- and wrote the result into the cache store with rememberForever(). The SMTP password, the S3 secret access key and the whole GCS service account key file, private key included, went in as plain text under a key that never expires. The cache store encrypts nothing. On the store INSTALL.md documents for a manual install (CACHE_STORE=database) and config/cache.php defaults to, that is the `cache` table of the same database whose dump the `encrypted` cast exists to survive. On redis it is the redis dump. The rule already exists, two files away. MailOAuthConnection states it: Transports read this row fresh at send time -- tokens must never travel through the boot-config cache (see MailConfigApplier, which caches only readiness and the account address). MailConfigApplier's own cache-key comment says the same thing about the same array: what is deliberately NOT in the cached shape is tokens, because neither readiness nor an address is a credential. The SMTP password was in it anyway. SocialSettings::available() names both classes outright as making the mistake. So the credentials are read the way the tokens already are: from the row, at the point that uses them. The cached array keeps everything that is not a credential, and each applier reads its secret inside the branch that configures a transport -- an installation on OAuth, on cloud, or one that has never opened the Email or Storage screen reads nothing extra. BootSettingsCache grows a second entry point rather than the callers restating its rule. The cached read already survives a database with no tables, because booting must not require this application's own database; an uncached credential read on the same path needs exactly that guarantee and nothing else, since resolve() can hand back a warm "configured" from a database that has since stopped answering. Both cache keys are bumped, as their comments require on a shape change. Tests: five for the absence, two of them against the database cache store read as the raw rows an operator would find in a dump, since phpunit.xml runs the suite on the array store and the cache path was structurally invisible -- which is why GoogleCloudStorageTest could assert that the private key is not in the column while it sat in the cache. All five were run against the unfixed appliers and fail there. The three "still configures what it no longer caches" tests deliberately pass either way: they pin the behaviour the fix must not break.
ProjectSend
Share files with your clients, from your own server.
ProjectSend is a self-hosted application for getting files to the people you work with. You upload what you want to send, choose exactly who can see it, and each client signs in to their own private page to download it.
No public link passed around by email, no third-party service holding your clients' documents, no per-seat pricing. It runs on your server, and the files stay there.
What it does
For the people you send to
- A private area per client, showing only what has been shared with them
- Sign in with an email address, with optional two-factor authentication
- Search, filter and sort their files; download one, several as a zip, or a whole folder
- Optional comments on a file, so questions live next to the thing they are about
- Email notifications when something new arrives, in their own language
For you
- Resumable uploads that survive a dropped connection, so large files actually arrive
- Organise with folders, categories and client groups
- Share with one client, a whole group, or publicly — and set an expiry date or a download limit
- Thumbnails and previews for images and documents
- Storage quotas per client, and custom fields for the details you need to keep on them
- A full activity log and download history: who got what, and when
For the installation
- Roles and permissions for your own team, so an uploader is not an administrator
- Sign-in the way you already work: LDAP, social sign-in, or plain email and password
- Themes for the client-facing pages and for outgoing email
- 16 languages
- A REST API with scoped tokens and generated OpenAPI docs
- Privacy controls, including GDPR-grade account erasure with a grace period
- Local disk, S3-compatible storage, or Google Cloud Storage
Screenshots
The dashboard — what is in the installation, and what has been happening in it.
Your library — folders, categories, and who each file is shared with.
What your client sees — only their files, nothing else.
Getting started
With Docker — the quickest path, and the one we recommend. Nothing to build: the published image ships with its dependencies and its frontend already compiled.
curl -O https://raw.githubusercontent.com/projectsend/projectsend/main/docker/production/compose.example.yaml
# edit the passwords and APP_URL in it, then:
docker compose -f compose.example.yaml up -d
Open APP_URL and the first thing you see is a setup screen that creates your administrator
account — or uncomment ADMIN_EMAIL and ADMIN_PASSWORD in the file first, with a password of
your own, and it is created for you.
Before you put real files in it, read DOCKER.md — where your database and uploads actually live, how to move them onto paths you chose, and how to back them up so an upgrade can't take them with it.
Without Docker — for servers where it isn't an option, install from a release zip.
INSTALL.md covers requirements, .env, nginx, the background worker and cron,
updating and troubleshooting. You do not need Composer or npm on the server; the zip ships ready to
run.
Already running it? UPDATE.md is how you move to a new version — one command on Docker, one script on your own server, and what to check afterwards either way.
Want to work on ProjectSend itself? Cloning the repository gets you a development copy, not an installation: the dependencies and the compiled frontend are deliberately not in git, so a clone needs Composer and npm before it runs. CONTRIBUTING.md has the sequence, and it is short.
Coming from ProjectSend Legacy?
The previous generation of ProjectSend lives on at projectsend/legacy. This is a rebuild rather than an upgrade, so moving across is an import rather than an update — install fresh, then bring your old site into it with the migration tool: accounts, clients, groups, categories, folders, files and history.
It never writes to your old install, and any run can be undone with a single command. MIGRATING-FROM-V1.md explains what comes across, the two routes (same machine, or a portable export from a server you can't reach), and the one change your clients will notice: they sign in with their email address now, using the same password.
