Title (EN) METHOD OF PROVIDING TEXT REPRESENTATION OF A CRYPTOGRAPHIC VALUE
(FR) PROCÉDÉ POUR FOURNIR UNE REPRÉSENTATION TEXTUELLE D'UNE VALEUR CRYPTOGRAPHIQUE
Abstract:
(EN) A method of representing cryptographic values in text form is described. The text representation is formed from words selected from a vocabulary, which may include a collection of pseudowords. The text representations can be further transformed to a paragraph in an apparently grammatically correct form.
(FR) L'invention concerne un procédé de représentation de valeurs cryptographiques sous forme textuelle. La représentation textuelle est formée de mots sélectionnés à partir d'un vocabulaire qui peut comprendre une collection de pseudo-mots. Les représentations textuelles peuvent être en outre transformées en un paragraphe sous une forme d'apparence grammaticalement correcte.
