Secure Temporary File & Text Sharing
Slack, Microsoft Teams, and standard email clients were fundamentally not designed for transmitting highly sensitive secrets. When you paste an API key, an AWS Root password, or a proprietary code snippet into a team chat, that data is permanently logged in plain text in their cloud infrastructure.
AcadShare solves this zero-trust security problem. It allows you to wrap sensitive text or business-critical files into an encrypted, password-protected temporary link that automatically self-destructs after it is viewed by your intended recipient.
How to Share Secrets Safely
- Drop Your Payload: Paste your secure text or upload a highly sensitive file (up to 20MB). If you are sharing credentials, use our Secure Password Generator first to mint a strong key.
- Set Strict Expiration Rules: Choose how long the link remains valid (e.g., 24 hours, 7 days) and strict download limits. A popular security posture is the "Burn After Reading" mode (1 Download limit), which ensures absolute single-access exclusivity.
- Protect with a Password: Generate a secondary decryption password. Send the temporary link via one communication channel (e.g., Email) and deliver the password via a separate channel (e.g., Slack) to prevent localized man-in-the-middle attacks.
- Send with Confidence: Once the payload is retrieved by the recipient (or the time expires), the underlying database record is irrevocably destroyed. No backups, no recovery.
Use Cases for Self-Destructing Links
- DevOps Credential Rotation: When onboarding a new engineer, you never want to permanently log their initial database URI or Base64 encoded Kubernetes config in an HR email thread. Acadshare ensures the onboarding secret evaporates the moment the engineer configures their local environment.
- Legal & Financial Documents: Sharing unreleased quarterly financial PDFs or signed NDAs across organizations is risky over raw email protocols. Our expiring file layer acts as a secure air-gap for critical documents.
- Client Handoffs: If you are a freelancer giving a client the master passwords to their new infrastructure, sending it via an automatically destructing link proves that you are adhering to peak cybersecurity communication standards.
Frequently Asked Questions
How long do my shared files remain active?
You can customize the expiration time. Shares can be set to self-destruct anywhere from 1 view up to a few maximum days before being purged forever.
What happens when a share link expires?
Once the time limit or download limit is reached, the file and all associated metadata are permanently and irrecoverably deleted from the database.
Is it safe to share API keys and passwords?
Yes. Using a self-destructing link ensures that the keys cannot be accessed later by unauthorized users browsing chat histories.
Can I limit the number of downloads?
Yes, you can set a strict download limit. A popular setting is 'Send Once' (1 download), which ensures the file is truly only viewed by the intended recipient.
How big of a file can I share?
Currently, AcadShare supports temporary secure file transfers up to 20MB per file to maintain secure encryption speeds.
