+# As previously thought, we exchange one IPFS hash through whatever means we can.

+# GPG is mentioned as a signing algorithm for encryption, decryption and signing.
+# Let's say we have a file named as `example`

+# We can extend this with calling the encoder and further send the transaction

+#FINGERPRINT="CHANGE THIS TO YOUR DEFAULT FINGERPRINT"
+# We acquire the GPG fingerprint by email address
