i get the binary bytes from somewhere, that is the key i am suppose to use
when i sign my document.
the api for javax.xml.crypto.dom.DOMCryptoContext wants a java.security.Key
object, not byte[]. but just looking at the api's, it's not clear to me how
i can go from one thing to the other. anyone can help?
thanks

You need to ask that "somewhere" how to convert these bytes into a key. They
can be anything for all we know - exported ascii, raw bytes of a keystore
file, a serialized Key object, etc.

后来好像是这样解决的. 我自己implement一个MyKey class, 然后, 写 getEncoded().
