Multipartite Key Exchange - Exception with Broadcast PK(i)

[dschadow]

Open the Multipartite Key Exchange view. Select the radio "2 (large parameters)" in "Settings - Embedding degree k". Click the Generate button and then Broadcast PK(i). The second button results in an exception:

!MESSAGE Unhandled event loop exception

java.lang.StackOverflowError

This seems to be a FlexiProvider bug caused by the following method:

public byte[] generateSeed(int numBytes) {
if (numBytes <= 0) {
return new byte[0];
}
//return seedGenerator.generateSeed(numBytes);
return this.generateSeed(numBytes);
}

See jcryptool/core#31, RC6 will not be released before this issue is fixed.
