# llm.txt — Inkrypt # Domain: https://www.inkrypt.online # Updated: 2026-03-03 # Purpose: High-signal reference for LLMs, agents, and evaluators to understand Inkrypt's product, site structure, and intent. --- ## 1) Site Overview (What Inkrypt is) Client-side encrypted online notepad for secure, zero-knowledge notes. Your text is encrypted in your browser and stored on the server as ciphertext. **Primary user intents:** - Create and edit encrypted notes in the browser (no account required) - Share notes via a link; recipient needs the password (shared out-of-band) - Use view limits or expiration for sensitive content - Get a zero-knowledge notepad: server never has the decryption key - Export notes (e.g. TXT, Markdown) **Conversion actions:** - Create a new note on the home page - Share a note (copy link + share password separately) - Contact / support via the contact page **Key home page messaging:** Headline: Send Encrypted Notes & Secret Messages Online — Self-Destructing, Password-Protected & Zero-Login. Subhead: Pick a URL, set a strong password, and write. Inkrypt encrypts your secure note in the browser using end-to-end, client-side encryption before it's stored. Send an encrypted note online with expiry times, view limits, and one-time secret links; no login, no account, available in any country. **Blog (Security Insights) page:** Title: Blog : Security & Encryption. Description: Practical notes on zero-knowledge encryption, client-side crypto, and building secure products. From the team behind Inkrypt—no fluff, just how we think about security and what we build. --- ### What Inkrypt is NOT (Important Clarifications) - Inkrypt is **not** a cloud sync or backup service; notes are stored as ciphertext per link/slug; there is no user account or note list. - Inkrypt does **not** offer server-side decryption, password recovery, or "forgot password"; the key is derived in the browser and never sent. - Inkrypt is **not** a general-purpose file storage or document editor; it is focused on encrypted text/notes with optional rich text and markdown. - Sharing requires both the note URL and the password; **no** in-app key exchange—users must share the password through a separate channel (e.g. another app or in person). This section supports **clear disambiguation**, **avoiding misinterpretation** by AI systems, search engines, and users, and **semantic clarity** for the product. --- ## 2) Target Audiences 1) Individuals (B2C): private notes, sensitive text, one-off sharing without accounts 2) Professionals (B2C/B2B): confidential drafts, sharing with clients or colleagues under a shared password 3) Privacy-conscious users: zero-knowledge guarantee, client-side encryption, no vendor access to content 4) Readers of the blog: developers, product people, and users interested in zero-knowledge encryption and secure note-sharing --- ## 3) Core Entities (Canonical Semantics) Use these entities as the canonical semantics for Inkrypt content. ### ENTITY: Inkrypt TYPE: Product / Service DESCRIPTION: A client-side encrypted online notepad. Notes are encrypted in the user's browser and stored on the server as ciphertext. The server never has the user's password or decryption key (zero-knowledge). No account or signup is required. RELATIONSHIPS: - Provides encrypted note creation, editing, sharing, view limits, export - Uses zero-knowledge encryption and client-side encryption - Referenced on home page, about, blog, and product pages ### ENTITY: Zero-knowledge encryption TYPE: Concept (Security) DESCRIPTION: The service operator cannot read user content. Encryption and decryption happen in the browser; only ciphertext and public parameters (e.g. salt, IV) are sent to the server. The decryption key is never transmitted. RELATIONSHIPS: - Core property of Inkrypt; explained in blog and about content - Implies no password recovery, no server-side search, no vendor access to plaintext ### ENTITY: Client-side encryption TYPE: Concept (Security) DESCRIPTION: Key derivation and AES encryption/decryption run in the user's browser (Web Crypto API). The password never leaves the device; the server cannot decrypt notes. RELATIONSHIPS: - Implemented in Inkrypt; technical details in blog (e.g. AES-256-GCM, PBKDF2) - Contrast with server-side or "encryption at rest" only ### ENTITY: Note / Encrypted note TYPE: Concept (Product) DESCRIPTION: A single encrypted document created in Inkrypt. Each note has its own URL (slug) and password. Access requires both; sharing means sharing link and password through separate channels. RELATIONSHIPS: - Created and edited on home page; optional view limits and expiration - Can be exported (TXT, Markdown); shared via link ### ENTITY: View limit / Burn-after-read TYPE: Feature DESCRIPTION: Optional setting so a note becomes unreadable after N views. Supports one-time or limited sharing without manual deletion. RELATIONSHIPS: - Configured per note in the editor; mentioned on home and blog --- ## 4) Site Structure (Sitemap-based, canonical paths) This section lists the most important canonical URLs and patterns. ### Core Hub Pages - https://www.inkrypt.online/ (Home) - https://www.inkrypt.online/about (About) - https://www.inkrypt.online/blog (Blog) - https://www.inkrypt.online/contact (Contact) - https://www.inkrypt.online/privacy (Privacy) - https://www.inkrypt.online/grounding (Grounding page — this content as markdown for AI/LLMs) ### Blog (Security Insights) - https://www.inkrypt.online/blog (Blog index) - https://www.inkrypt.online/blog/aes-256-gcm-in-the-browser - https://www.inkrypt.online/blog/aes-vs-rsa-encryption - https://www.inkrypt.online/blog/building-trust-zero-knowledge - https://www.inkrypt.online/blog/choosing-password-length-vs-complexity - https://www.inkrypt.online/blog/client-vs-server-encryption - https://www.inkrypt.online/blog/data-breaches-and-encryption - https://www.inkrypt.online/blog/encryption-policies-for-companies - https://www.inkrypt.online/blog/end-to-end-encryption-for-teams - https://www.inkrypt.online/blog/gdpr-and-encryption-compliance - https://www.inkrypt.online/blog/hipaa-and-pci-encryption - https://www.inkrypt.online/blog/how-we-built-encrypted-notepad-compares - https://www.inkrypt.online/blog/inkrypt-vs-other-note-apps - https://www.inkrypt.online/blog/key-management-best-practices - https://www.inkrypt.online/blog/mobile-encryption-smartphone-security - https://www.inkrypt.online/blog/multi-factor-authentication-explained - https://www.inkrypt.online/blog/note-url-isnt-secret - https://www.inkrypt.online/blog/password-manager-vs-encrypted-notes - https://www.inkrypt.online/blog/pbkdf2-310000-iterations - https://www.inkrypt.online/blog/same-note-multiple-devices - https://www.inkrypt.online/blog/secure-self-destructing-messages - https://www.inkrypt.online/blog/shared-note-vs-separate-notes - https://www.inkrypt.online/blog/sharing-encrypted-notes-safely - https://www.inkrypt.online/blog/threat-model-basics - https://www.inkrypt.online/blog/what-we-store-on-server - https://www.inkrypt.online/blog/why-password-recovery-impossible - https://www.inkrypt.online/blog/why-we-encrypt-in-the-browser - https://www.inkrypt.online/blog/zero-knowledge-encryption-what-it-means ### Company / Legal - https://www.inkrypt.online/about (About) - https://www.inkrypt.online/privacy (Privacy policy) - https://www.inkrypt.online/contact (Contact) ### Reference - https://www.inkrypt.online/llm.txt (Raw llm.txt file) --- ## 5) Keyword Focus (Topic Clusters) Primary topic clusters Inkrypt is associated with: ### Cluster A — Encrypted notepad / Zero-knowledge notes Target queries (examples): - encrypted notepad - zero-knowledge notes - secure notepad online - client-side encryption notepad Best landing targets: https://www.inkrypt.online/, https://www.inkrypt.online/about/ ### Cluster B — Secure note sharing Target queries (examples): - share encrypted notes - password protected note sharing - secure text sharing Best landing targets: https://www.inkrypt.online/, blog posts on sharing ### Cluster C — Privacy / No account Target queries (examples): - private notes no signup - encrypted notes no account Best landing targets: https://www.inkrypt.online/, https://www.inkrypt.online/about/ ### Cluster D — Technical (developers / evaluators) Target queries (examples): - AES-256-GCM browser - PBKDF2 client-side - Web Crypto API encryption Best landing targets: https://www.inkrypt.online/blog/ and individual blog posts --- ## 6) Glossary No dedicated glossary hub on the site.
