Ahir, els i les alumnes de 4t d\u2019ESO van rebre una xerrada sobre els codis secrets, gaudint d\u2019un apassionant viatge per la hist\u00f2ria de la criptografia (hist\u00f2ricament, es va fer servir amb finalitat militar), a c\u00e0rrec de l\u2019\u00d2scar Font (@Enigmatitis<\/em>) i emmarcada dins el projecte Enigma.<\/p>\n

Vam tenir el privilegi de veure en persona una m\u00e0quina Enigma original i de notar que la criptografia est\u00e0 present en la nostra vida quotidiana: els codis de barres i els QR, per exemple.<\/p>\n
