Halina Ryffert (4 February 1916 - 7 August 1996) was a Polish cryptographer, mathematician, and professor of acoustics. During the war, she created a one-person cipher cell to ensure the secure transmission of information between the country and the government in exile.[1][2][3]

The work was strenuous, requiring great concentration and attention, as each letter was encrypted separately and the slightest mistake could change the information the need to completely eradicate all traces of work after each encryption of several hours, required great vigilance and tension – she recalled years later.[4]
