+## Maven Public Key
+
+The file [bc_maven_public_key.asc](bc_maven_public_key.asc) contains the public key used to sign our artifacts on Maven Central. You will need to use 
+
+```
+gpg -o bc_maven_public_key.gpg --dearmor bc_maven_public_key.asc
+```
+
+to dearmor the key before use. Once that is done, a file can be verified by using:
+
+```
+gpg --no-default-keyring --keyring ./bc_maven_public_key.gpg --verify  file_name.jar.asc file_name.jar
+```
+
+Note: the ./ is required in front of the key file name to tell gpg to look locally.
+
