msgdrop - use ntfy.sh to send encrypted messages
msgdrop send [OPTION] [KEYPAIR] [FILE]...
msgdrop recv [OPTION]
msgdrop genkey [OPTION]
Use ntfy.sh to send and receive encrypted messages using a "random" topic ID.
The topic ID is generated by taking the md5sum of the recipient's public key.
msgdrop send will join all provided FILEs using cat(1) prior to encryption.
If no files are provided, standard input is read instead. The message will be
broken into chunks in order to keep the individual message within the limits
imposed by ntfy.sh.
msgdrop recv reads all unread messages in the topic, decrypts them using your
public key, and sends them to standard output.
-d Directory to save keypairs (default: $XDG_CONFIG/msgdrop)
-h Print a help message and exit.
-v Display version information.
-d [DELAY] seconds to delay between successive message chunks (Default = 1).
-l [LENGTH] maximum length of a message chunk. Must be between 50 and 900
(Default = 140).
-a Read all messages
-k [KEYPAIR] Use a different keypair name than the default. (Default =
msgdrop).
-k [KEYPAIR] Use a different keypair name than the default. (Default =
msgdrop).
msgdrop send recipient file1 file2
Encrypt the concatenated contents of file and file2 using recipient as the
encryption key and topic ID.
echo "Hello world" | msgdrop send recipient
Encrypt the string "Hello world" using recipient as the encryption key and
topic ID.
msgdrop recv
Read unread messages, decrypting with your default key.
msgdrop recv -a
Read all messages, using your default key to decrypt.
msgdrop recv -k foo
Read unread messages sent to foo, decrypting with your the foo key.
msgdrop requires age and an age(1) keypair to perform the encryption and decryption.
msgdrop genkey [-k KEYPAIR]
Creates a keypair using the default name msgdrop or KEYPAIR.
