Glossary

This glossary explains key terms used across TaskNote. Each definition links to pages where the concept is explained in context.

Encryption and Security

End to End Encryption #: End to End Encryption means that notes are encrypted on the user device before being sent to the server and can only be decrypted by the user. The server never has access to readable content.

AES-GCM (256-bit)#: AES-GCM (256-bit) is an authenticated encryption algorithm that combines strong data confidentiality with integrity verification. It encrypts data using a 256-bit key and ensures that encrypted content cannot be modified without detection. TaskNote uses AES-GCM on the client side to encrypt notes before they are stored or synced, providing high security with minimal performance overhead.

FAQ
Encryption Key #: An Encryption Key is a secret value used to encrypt and decrypt note content. In TaskNote, the key is derived from the user password and never stored on the server in plain form.

FAQ
Client Side Encryption #: Client Side Encryption means that all encryption and decryption operations happen directly in the browser or app before data is synced to the server.

FAQ
Local Encryption#: Local Encryption refers to encrypting data directly on the device before storage or synchronization.
Decryption#: Decryption is the process of converting encrypted data back into readable form using the correct encryption key.

Encrypted Data#: Encrypted Data is information that has been transformed into an unreadable format to protect it from unauthorized access.
Used in
Encryption
Plain Text#: Plain Text is readable, unencrypted data before encryption or after successful decryption.
Cipher#: A Cipher is an algorithm used to perform encryption and decryption of data.
Key Derivation#: Key Derivation is the process of generating a secure encryption key from a password using cryptographic algorithms.
Password Based Encryption#: Password Based Encryption uses a user password to derive an encryption key instead of storing a key directly.
Hashing#: Hashing is a one way process that converts data into a fixed length value. It is commonly used for password verification.
Salt#: A Salt is random data added to a password before hashing to improve security and prevent precomputed attacks.
Encryption at Rest vs. In Transit #: Encryption at Rest protects data stored on disk, while Encryption in Transit protects data moving over the network. TaskNote uses both, plus Client-Side Encryption for total privacy.

Secure Storage#: Secure Storage refers to storing encrypted data in a way that prevents unauthorized access even if the storage is compromised.

Authentication and Access

Account Password#: Account Password is the secret used by the user to authenticate and unlock encrypted notes.
Master Password#: Master Password is the primary password used to derive encryption keys and protect all note content.
Session#: A Session is a temporary authenticated state that allows the user to access the app without logging in repeatedly.
Authentication#: Authentication is the process of verifying a user identity using credentials such as a password.
Authorization#: Authorization determines what actions an authenticated user is allowed to perform.
Login Session#: Login Session is the active period during which a user remains logged in.
Logout#: Logout ends the current session and removes access until reauthentication.
Password Reset#: Password Reset allows a user to set a new password. Depending on encryption setup, this may affect access to existing encrypted data.
Two Factor Authentication#: Two Factor Authentication adds an extra verification step during login to improve account security.
Two Factor Authentication#: Two Factor Authentication adds an extra verification step during login to improve account security.
Recovery Key #: A Recovery Key is an optional backup key that can help restore access if the main password is lost.

Notes and Data

Note#: A Note is a single piece of written content stored inside TaskNote.
Task#: A Task is an action item created inside TaskNote to track work, personal to dos, or next steps. Tasks live alongside notes and can be checked off when completed, keeping planning and execution in one workspace.
