* --add-key works and you are now able to generate subkeys.
* It is now possible to generate ElGamal keys in v4 packets to create
valid OpenPGP keys.
* Some new features for better integration into MUAs.

the United States until Sep 20, 2000). I'm sorry about this, but
this is the world we have created (e.g. by using proprietary software).
Because the OpenPGP standard is still a draft, GNUPG is not yet
compatible with it (or PGP 5) - but it will be. The data structures
used are compatible with PGP 2.x, so it can parse and list such files
and PGP should be able to parse data created by GNUPG and complain
about unsupported algorithms.
Because the OpenPGP standard is still a draft, GNUPG now interoperates
with it and PGP 5. The MUA Mutt will soon support GNUPG; it has a
mode to fallback to another program if the received message has been
created with RSA or IDEA.
The default algorithms used by GNUPG are ElGamal for public-key
encryption and signing; Blowfish with a 128 bit key for protecting

Because we have no hardware device to generate randomness we have to
use this method.
Key generation shows progress by printing different characters to

"^" Checking a new value for the generator
"<" Size of one factor decreased
">" Size of one factor increased
The prime number for ElGamal is generated this way:
1) Make a prime number q of 160, 200, 240 bits (depending on the keysize)
2) Select the length of the other prime factors to be at least the size
of q and calculate the number of prime factors needed
3) Make a pool of prime numbers, each of the length determined in step 2
4) Get a new permutation out of the pool or continue with step 3
if we have tested all permutations.
5) Calculate a candidate prime p = 2 * q * p[1] * ... * p[n] + 1
6) Check that this prime has the correct length (this may change q if
it seems not to be possible to make a prime of the desired length)
7) Check whether this is a prime using trial divisions and the
Miller-Rabin test.
8) Continue with step 4 if we did not find a prime in step 7.
9) Find a generator for that prime.

If you decided to create a DSA key, you should add an ElGamal
for encryption:
gpg --add-key user_id_of_your_key
and follow the displayed instructions (select "ElGamal using v4 packets").
You can sign a key with this command:

"!" Reloading the pool with fresh prime numbers
"^" Checking a new value for the generator
"<" Size of one factor decreased
">" Size of one factor increased
The prime number for ElGamal is generated this way:
1) Make a prime number q of 160, 200, 240 bits (depending on the keysize)
2) Select the length of the other prime factors to be at least the size
of q and calculate the number of prime factors needed
3) Make a pool of prime numbers, each of the length determined in step 2
4) Get a new permutation out of the pool or continue with step 3
if we have tested all permutations.
5) Calculate a candidate prime p = 2 * q * p[1] * ... * p[n] + 1
6) Check that this prime has the correct length (this may change q if
it seems not to be possible to make a prime of the desired length)
7) Check whether this is a prime using trial divisions and the
Miller-Rabin test.
8) Continue with step 4 if we did not find a prime in step 7.
9) Find a generator for that prime.
