Hi There,

Hi There,
Does anyone know, how to create Public/PrivateKey from a byte[] without
knowing its encoding/algorithm?
This is to set KeyInfo and or signingKey in XMLSignature.

Thanks.

Hi,

If I correctly understand your question, you have a byte array and need 
a Key object, don't you ?
In this case you can use the java cryptography extensions, like this:

KeyFactory kf = KeyFactory.getInstance(algrithm);
PublicKey pk = kf.generatePublic(new X509EncodedKeySpec(byte[] encodedKey));

If you are not using an X509 certificate, refer to Sun jdk api 
documentation for the names of other algorithms.

Bye
