Valorizzazione <SignatureValue>

[aresares]

Buongiorno,
avevo una domanda riguardo la valorizzazione del tag <ds:SignatureValue> ????????? </ds:SignatureValue>. Cosa bisogna inserire dentro questo tag?
Usando i script sono riuscito a generare le due chiavi key.pem e csr.pem ma non sparei come valorizzare SignatureValue

al momento il mio metadata è cosi

usa un tool per la firma del metadata, all'interno di questo devi solo predisporre il template, guarda qui
