Hi Guys,
I'm getting an error message when generating a 2048 bit DSA key:

Terminate called after throwing an instance of 'CryptoPP::InvalidArgument'
  what():  DSA: not a valid prime length

Reading the Wiki, I'm actually not quite sure whether Crypto++ supports 2048 
bit DSA keys. As I understand they are allowed according to FIPS 186-3. I did 
undefine "DSA_1024_BIT_MODULUS_ONLY" but that (expectedly) didn't help. 
According to DSA::MAX_PRIME_LENGTH the maximum key size should be 1024 bits, 
which explains the error message.

Where should I tweak?
