Paperclip has an interpolation called `:hash` for obfuscating filenames of
publicly-available files. For more on this feature read the author's own
explanation.
publicly-available files.
[https://github.com/thoughtbot/paperclip/pull/416](https://github.com/thoughtbot/paperclip/pull/416)
Example Usage:
has_attached_file :avatar, {
:url => "/system/:hash.:extension",
:hash_secret => "longSecretString"
}
The `:hash` interpolation will be replaced with a unique hash made up of whatever
is specified in `:hash_data`. The default value for `:hash_data` is `":class/:attachment/:id/:style/:updated_at"`.
`:hash_secret` is required, an exception will be raised if `:hash` is used without `:hash_secret` present.
