Update of /cvsroot/freenet/freenet/src/freenet/crypt
In directory sc8-pr-cvs1:/tmp/cvs-serv9009/src/freenet/crypt
Modified Files:
DSAPublicKey.java
Log Message:
6278:
Make Identify a (more or less) regular message. We pull the ref off it when we receive
it, but later it gets executed by NewIdentify, which asks RT if it wants it, and if it
does, verifies the signature (significant CPU operation!), and adds it.
Do NOT verify references on the RSL thread.
