Send Files and Messages

The encryption keys are NOT shared with the Finch server. The server has NO way to decrypt your data. To encrypt and upload a file:

$ finch -f file_path -t transaction_file

Maximum file size is 16MB. The transaction_file is a text file that contains a random encryption key and transaction id. Anyone who has the file will be able to download and decrypt the uploaded file and message.

To send encrypted message:

$ finch -m "Some message" -t transaction_file

You can also send a file along with a message:

$ finch -f file_path -m "Some message" -t transaction_file
