## Encrypts and signs JSON using the provided key, returning base64-encoded

## data ready to be submitted to Guacamole and used by the guacamole-auth-json
|
|
## authentication provider. Beware that this base64-encoded must still be

|
## URL-encoded prior to submission to /api/tokens via POST. Base64 encoding may
|
|
## contain + and = characters, which have special meaning in URLs.
|
|
##
|

## curl --data-urlencode "data=$(<file_containing_result)" GUAC_URL/api/tokens
