    Subject: DSA and Signature

Hi,

I was just wondering why when the algorithm "DSA" is passed
to the Signature getInstance() method it performs a lookup
for the algorithm "SHA/DSA"?

In the Signature.getInstance() method there is;

if (algorithm.equalsIgnoreCase("DSA"))
algorithm = new String("SHA/DSA");

But the JCA specification makes no mention of this! It
does specify the correct name for the algorithm is SHAwithDSA
but there is no mention of SHA/DSA.
