Access key and Secret key are your identifiers for Amazon S3. Leave them empty for using the env variables.
Access Key []: 3WD7VXGJ8ZO0UBTFM5XR
Secret Key []: 11111111
Default Region [US]: 

Encryption password is used to protect your files from reading
by unauthorized persons while in transfer to S3
Encryption password: 
Path to GPG program [/usr/bin/gpg]: 

When using secure HTTPS protocol all communication with Amazon S3
servers is protected from 3rd party eavesdropping. This method is
slower than plain HTTP, and can only be proxied with Python 2.7 or newer
Use HTTPS protocol [No]: 

On some networks all internet access must go through a HTTP proxy.
Try setting it here if you can't connect to S3 directly
