It is reported that cfme contains a default salt value:
lib/util/miq-password.rb
def initialize(str=nil, enc_alg=nil, key=nil, iv=nil)
@enc_alg = enc_alg || @@enc_alg || "AES-128-CBC"
@key = key || @@key || "1234567890123456"
@iv = iv || @@iv || "6543210987654321"
@encStr = nil
This negates the value of having a salt function with respect to password storage.
