WebCriptografia cu chei simetrice se referă la metode de criptare în care atât trimițătorul cât și receptorul folosesc aceeași cheie (sau, mai rar, în care cheile sunt diferite, dar într-o relație ce la face ușor calculabile una din cealaltă). Acest tip de criptare a fost singurul cunoscut publicului larg până în 1976.
