reçois la sortie avec inférieure à la valeur (car elle fait référence méthode DSA)
<ds:SignatureMethod Algorithm="http://www.w3.org/2000/09/xmldsig#dsa-sha1"/>
mais j'ai besoin d'une valeur avec (avec la méthode HMAC_SHA1)
<SignatureMethod Algorithm="http://www.w3.org/2000/09/xmldsig#hmac-sha1"/>
donc je modifié le code avec SignatureMethod.HMAC_SHA1 au lieu de SignatureMethod.DSA_SHA1 alors il a commencé à me donner l'exception ci-dessous et également ne suis pas en mesure de trouver le KeyPairGenerator approprié pour HMAC_SHA1.
