Parchemin offers a secure, ephemeral, and zero-knowledge solution for sharing sensitive information like passwords, API keys, private tokens, and confidential documents. It addresses the critical security flaw of traditional communication methods (email, Slack, Teams) which leave permanent plaintext records. With Parchemin, secrets exist only as long as needed and are accessible only by their intended recipient.
The platform utilizes zero-knowledge end-to-end encryption, encrypting notes directly in the browser using the proven OpenPGP standard. Crucially, the decryption key is embedded exclusively in the URL fragment (#) and is never transmitted to or stored on Parchemin's servers, ensuring that even the service provider cannot access the content.
Notes are designed for self-destruction and ephemeral data management. Users can configure notes to "burn after reading" or set an automatic expiration time ranging from 1 hour to 30 days. Upon viewing or expiration, the encrypted payload is permanently and irrevocably deleted from the systems, minimizing data retention risks.
A core principle of Parchemin is its 100% ad-free and tracker-free environment. Unlike many legacy tools, it contains no advertising, tracking pixels, or third-party analytics scripts, guaranteeing that user security and privacy are never compromised by external networks.
Parchemin is built for teams and businesses, providing administrators with tools to enforce compliance and security policies. These include mandatory expiration caps to prevent secrets from persisting beyond internal guidelines, the option to require a secondary password for specific domains or workspaces, and the ability to enforce a strict single-read rule for immediate self-destruction.
Furthermore, the service requires no recipient account. This simplifies sharing with external providers, customers, or colleagues, allowing recipients to instantly open and decrypt notes in any modern browser without the need for registration or application installation.
The process is straightforward:
- Create your note: Users can write messages, upload files, or record audio notes.
- Set your security options: Choose an expiration period, enable burn-after-reading, or add a password. For team members, company policies are automatically applied.
- Share the encrypted link: Parchemin generates a unique, single-use link containing the client-side decryption key, which is then sent to the recipient via their preferred communication channel.
- Permanent destruction: The encrypted content is irreversibly deleted from the database as soon as it is read or expires.
This robust approach ensures that sensitive information is shared with complete peace of mind, adhering to high standards of privacy and data security.
