    Hi nativenvs,

    welcome to the GPGTools support platform. Sorry you are having problems using GPG Suite.

    The message you are trying to decrypt is in RTF file format. Wikipedia says: "The Rich Text Format (often abbreviated RTF) is a proprietary document file format developed by Microsoft Corporation from 1987 until 2008 for cross-platform document interchange with Microsoft products."

    RTF is formatted text and the problem with formatted in case of OpenPGP messages is, it tends to destroy their structure and render them useless.

    To exchange OpenPGP messages please use .txt file format. For keys you can use the key servers or if that is not an option also use .txt or .asc file format.

    It might be the best idea, to ask the message author to resend the message in .txt format.

    In case you yourself are the author: Would it be possible to share the message that is causing this error message with us. To prevent the message being altered during transit, please visit your discussion in your browser. Then type "@@@" without the, two linebreaks, paste your message, again two linebreaks and again type @@@.

    We will then take a closer look at the message and try to understand, why it is not being decrypted.
