Upgrade the encryption for previously encrypted text
The following table describes which clients support which versions of our encrypted text:
Be sure to update your Evernote client to the latest version and follow the instructions in the following section to re-encrypt your content. If you want to increase the security of that content, you need to first decrypt and then re-encrypt the content on a desktop client. Notes previously encrypted using RC2Īny note content you encrypted prior to the encryption improvement will remain encrypted using RC2. This means that if you forget your passphrase, your data cannot be recovered. This key, along with an initialization vector, is used to encrypt your data in CBC (Cipher Block Chaining) mode.Įvernote never receives a copy of this key or your passphrase and doesn’t use any escrow mechanism to recover your encrypted data. Your passphrase, along with a unique salt, runs through a HMAC/SHA-256 hashing function 50,000 times. Prior to that time, Evernote used RC2 encryption with a 64 bit key, derived from a passphrase you chose.Įvernote derives your AES key from the passphrase you enter and does this using a well recognized method called PBKDF2 (Password Based Key Derivation Function 2). In February 2014, Evernote made a conscious effort to improve the security of in-note encryption and began using AES (Advanced Encryption Standard) with a 128 bit key. If you are using an Evernote desktop client, such as Windows Desktop and Evernote for Mac, you can encrypt any text inside a note to add an extra level of protection to private information. What type of encryption does Evernote use? Encrypted text supported
