Roberto Panetta has updated CryptoEdit for the Mac to version 2.3. The upgrade is optimized for macOS Mojave.

The utility lets you create and edit “encrypted by default” documents. CryptoEdit can manage TEXT, RTF and RTFD (with images) formats. It saves documents on disk as encrypted and is designed as a solution to manage reserved documents with formatted text and images.

CryptoEdit requires macOS 10.10 or higher. It costs $4.99 and is available at http://www.ecleti.com/osx/cryptoedit/.
