OpenSAML convalida (2.0) Firma non funziona

Question

Problema:

Sto usando OpenSAML di costruire un mezzo per autenticare la risposta SAML 2.0 sui server Symantec. Ho lavorato per la maggior parte, con la possibilità di accedere ai vari aspetti dell'asserzione. L'unico problema è che quando cerco di convalidare la firma utilizzando la chiave pubblica di seguito, si afferma che "Signature non ha convalidato la chiave della credenziale".

Qualche idea?

Bene, è t urna che il codice sopra è corretto. Era la risposta SAML di esempio che non era corretta. Immagino che la lezione da trarre da tutto questo sia quella di fidarsi dell'implementazione :)
