Back in October 2016, Wikileaks changed the dates on a few files to 01-01-1984.
So I followed the lead and looked up page 101 of 1984. In it, the main character has been caught and is being tortured by the secret police. The conversation references a poem where the party had unsuccessfully tried to erase the word God.
The poem is M'Andrew's Hymn by Rudyard Kipling.
The idea dawned on me, perhaps this could be the password to the wikileals files, perhaps this poem and the song Across the Green Mountain by Bob Dylan that Assange posted on twitter before he went into isolation in the embassy.
Again, the poem is M'Andrew's Hymn by Rudyard Kipling and the song is Across the Green Mountain by Bob Dylan.
If you have the files with you, do try them out, who knows, this might be the password
