Encryption explained-How privnote keeps your private messaging under lock and key?

private messaging

The internet has connected us in ways never before imagined. With the tap of a finger, we instantly communicate across the globe. However, with great power comes great responsibility. When sharing sensitive information online, encryption is essential for keeping private messages secure. Understanding encryption empowers users to protect communications in an increasingly interconnected world its role in securing Privnote, and how the service enables users to share ephemeral messages without compromising privacy.

Encryption is the process of encoding information in such a way that only authorized parties’ access it. It protects data by making it unreadable to unwanted eyes. Encryption uses complex algorithms to scramble plain text input into ciphertext.  As long as the system’s encryption keys remain private, the encrypted data be deciphered and read by recipients with the matching key.  There are two main types of encryption: symmetric and asymmetric. Symmetric encryption uses the same key to encrypt and decrypt data. Asymmetric encryption uses two mathematically related keys – a public key to encrypt data and a private key to decrypt it. Both methods prevent third parties from accessing communications unless they possess the required keys.

Privnote secures messages with encryption

Privnote is a private messaging service that leverages encryption to safeguard user communications. The platform allows individuals to share text, links, files, and images that self-destruct after being read. It protects sensitive information from being exposed online indefinitely. Here is how Privnote encrypts data in transit:

  • When a user creates a new note, the plain text content is encrypted client-side using AES-256 symmetric encryption. It generates a unique ciphertext for each note.
  • The encrypted note is sent to Privnote’s server over HTTPS. The TLS protocol secures the connection and prevents eavesdropping read full info here
  • Upon receipt, the server stores the encrypted note in Privnote’s database. Without the original AES key, the ciphertext remains indecipherable.
  • When a recipient opens the note, the AES key is retrieved from browser storage and the ciphertext gets decrypted client-side. The decrypted plain text is then displayed to the authorized viewer.
  • After the set viewing period, Privnote wipes the AES key stored in the browser, rendering the note irrecoverable. The encrypted ciphertext remains on Privnote’s server without its corresponding key.

Privnote’s encryption approach ensures messages remain confidential while in transit and storage. The unique AES keys generated for each note prevent unauthorized access – even by Privnote itself. This provides peace of mind when sharing sensitive information online. By letting users place an expiration date on encrypted messages, Privnote reduces long-term privacy risks. It provides an important safeguard as more personal communications occur online. Encryption is an empowering tool for taking control of your digital security. Privnote leverages encryption and ephemeral messaging to enable private communications with reduced risks. By understanding the basics of cryptographic protection, users better safeguard sensitive information transmitted online. In an age of widespread data collection, encryption provides a shield against unwanted surveillance, securing our right to digital privacy.
