You can encrypt messages with my PGP public key. Encryption guide:

$ curl --tlsv1.3 --max-redirs 0 https://github.com/Proximyst.gpg | gpg --import -
$ echo 'get your message here' | gpg --encrypt --armor --recipient 'Mariell Hoversholm' --output message.asc
# The message is now in message.asc.

Alternatively, use one of my age keys. Encryption guide:

$ echo 'get your message here' | age --encrypt -o msg.txt.age -r 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
