Having set a computer to the problem of coming up with a Sophie Germain
prime for the E startup protocol (Diffie-Hellman), I offer you:
static final BigInteger g = new BigInteger("2");
static final BigInteger modulus =
new BigInteger("11973791477546250983817043765044391637751157152328012"
+ "72278994477192940843207042535379780702841268263028"
+ "59486033998465467188646855777933154987304015680716"
+ "74391647223805124273032053960564348124852668624831"
+ "01273341734490560148744399254916528366159159380290"
+ "29782321539388697349613396698017627677439533107752"
+ "978203");
