Tries to autodetect if the item’s raw hash appears to be encrypted.
# File lib/chef/encrypted_data_bag_item/check_encrypted.rb, line 26 def encrypted?(raw_data) data = raw_data.reject { |k, _| k == "id" } # Remove the "id" key. # Assume hashes containing only the "id" key are not encrypted. # Otherwise, remove the keys that don't appear to be encrypted and compare # the result with the hash. If some entry has been removed, then some entry # doesn't appear to be encrypted and we assume the entire hash is not encrypted. data.empty? ? false : data.reject { |_, v| !looks_like_encrypted?(v) } == data end
Private Instance Methods

Checks if data looks like it has been encrypted by Chef::EncryptedDataBagItem::Encryptor::VersionXEncryptor. Returns true only when there is an exact match between the VersionXEncryptor keys and the hash’s keys.
# File lib/chef/encrypted_data_bag_item/check_encrypted.rb, line 41 def looks_like_encrypted?(data) return false unless data.is_a?(Hash) && data.key?("version") case data["version"] when 1 Chef::EncryptedDataBagItem::Encryptor::Version1Encryptor.encryptor_keys.sort == data.keys.sort when 2 Chef::EncryptedDataBagItem::Encryptor::Version2Encryptor.encryptor_keys.sort == data.keys.sort when 3 Chef::EncryptedDataBagItem::Encryptor::Version3Encryptor.encryptor_keys.sort == data.keys.sort else false # version means something else... assume not encrypted. end end
