Can not generate a new key pair.

[David L Smith]

This is the first time I have used Gnupg.  I read the online manual at
www.gnupg.org, read the README that came with the distribution.  The
first thing I did after installing was the command "gpg --gen-key",  I
got the following results:
[dlsmith@C255422-A dlsmith]$ gpg --gen-key

About to generate a new ELG-E keypair.
              minimum keysize is  768 bits
              default keysize is 1024 bits

What keysize do you want? (1024) 
Requested keysize is 1024 bits   
Please specify how long the key should be valid.
         0 = key does not expire
      <n>  = key expires in n days
      <n>w = key expires in n weeks
      <n>m = key expires in n months
      <n>y = key expires in n years
Key is valid for? (0) 
Key does not expire at all
Is this correct (y/n)?
