Translations for cipher in French

Here are paragraphs from public domain books translated:
Anne of Austria re-entered her apartment, and came out again almost immediately, holding a rosewood casket in her hand, with her cipher encrusted with gold. Et Anne d’Autriche rentra dans son appartement et en sortit presque aussitôt, tenant à la main un petit coffret en bois de rose à son chiffre tout incrusté d’or.

So saying, he pulled out his own handkerchief, likewise a very elegant handkerchief, and of fine cambric--though cambric was dear at the period--but a handkerchief without embroidery and without arms, only ornamented with a single cipher, that of its proprietor. À ces mots, il tira son propre mouchoir, mouchoir fort élégant aussi et de fine batiste, quoique la batiste fût chère à cette époque, mais mouchoir sans broderie, sans armes et orné d’un seul chiffre, celui de son propriétaire.
