Hi All,
=20
Can anyone tell me are there any restrictions on the keys used for
authentication? I am using keys generated by puttygen-x86, my code is as
follows:
=20
transport =3D new SSH2Transport(serverSocket, createSecureRandom());
client =3D new SSH2SimpleClient(transport, username, keyFile, "");
=20
This is where it seems to die. I=92ve verified that all the arguments =
are
as they should be and the error message I=92m getting is:
Exception in thread "main" java.lang.Error: In ASN1OIDRegistry: null
        at
com.mindbright.asn1.ASN1OIDRegistry.addModule(ASN1OIDRegistry.java:86)
        at
com.mindbright.ssh2.SSH2KeyPairFile.<clinit>(SSH2KeyPairFile.java:105)
        at
com.mindbright.ssh2.SSH2SimpleClient.<init>(SSH2SimpleClient.java:84)
=20
        at Console.connect(Console.java:101)
        at Jerbil.main(Jerbil.java:36)
=20
At the moment I=92m taking it that the above means that the argument
=93moduleName=94 in ASN1OIDRegistry.addModule is null. Is this a (known)
bug, or am I doing something silly?
=20
Thanks in advance,
=20
Declan
