You can format the encrypted data as an the Evernote Secret button format, which can be decrypted by clicking the button.

It also provides a command to encrypt the selected text as the Evernote secret format.

If you plan to import notes from Evernote, try obsidian-importer-for-evernote-decryptor, which is forked version of importer plugin and formats the encrypted data as the Evernote secret format directly. About obsidian-importer-for-evernote-decryptor, see below.

This plugin is inspired by the inline-encrypter.

[!NOTE] A decryption method is based on the article: Decoding the Evernote en-crypt field payload.

[!WARNING] This plugin support the method using AES-128bit, which was introduced in 2014 (What type of encryption does Evernote use? – Evernote Help & Learning). Old encrypted data with RC2 encryption is not supported.

Following commands will be added:

• Decrypt Evernote encrypted data: Decrypt the selected encrypted text by entering the password and show the decrypted text.

• Decrypt Evernote encrypted data and replace: Decrypt the selected encrypted text and replace the text with the decrypted text.

Evernote secret format is a inline-code block starting with evernote_secret .

My secret is `evernote_secret <encrypted data>`.

This formatted text is viewed as a button of Evernote Secret in both reading and live preview mode.

By clicking the button, the password input dialog will be shown and the decrypted text will be displayed in a modal.

You can directly edit the encrypted text as a inline-code block, too.

Settings

The plugin provides a settings tab under the Obsidian settings menu:

• Show Editor Context Menu Item: Toggle the display of the editor context menu items.

About encrypted string of Evernote

Evernote makes the encrypted data with reserved starting value: ENC0.

This results in the encrypted data starting with RU5DM.

Therefore, you can find the encrypted data by searching RU5DM in the note.

If the encrypted data is not starting with RU5DM, it could be a old encrypted data with RC2 encryption, which is not supported, or it could be corrupted data.

By Format all Evernote secrets in the note command, all strings starting with RU5DM in the note will be formatted as the Evernote secret format.

If the string is in the code block (including inline code block), bold, italic, or strikethrough, it will not be formatted.
