Crypt::DSA::KeyChain - DSA key generation system
my $keychain = Crypt::DSA::KeyChain->new;
my $key = $keychain->generate_params(
Size => 512,
Seed => $seed,
Verbosity => 1,
is a lower-level interface to key generation than
the interface in Crypt::DSA
method). It allows you
to separately generate the p
, and g
given an optional starting seed, and a mandatory bit size for p
are 160 bits each).
You can then call generate_keys
to generate the public and private
portions of the key.
Constructs a new Crypt::DSA::KeyChain
object. At the moment this isn't
particularly useful in itself, other than being the object you need in order
to call the other methods.
Returns the new object.
Generates a set of DSA parameters: the p
, and g
of the key. This involves finding primes, and as such it can be a relatively
When invoked in scalar context, returns a new Crypt::DSA::Key
In list context, returns the new Crypt::DSA::Key
object, along with: the
value of the internal counter when a suitable prime p
was found; the
value of h
was derived; and the value of the seed (a
20-byte string) when q
was found. These values aren't particularly
useful in normal circumstances, but they could be useful.
The size in bits of the p value to generate. The q and
g values are always 160 bits each.
This argument is mandatory.
A seed with which q generation will begin. If this seed does not lead
to a suitable prime, it will be discarded, and a new random seed chosen in
its place, until a suitable prime can be found.
This is entirely optional, and if not provided a random seed will be
Should be either 0 or 1. A value of 1 will give you a progress meter during
p and q generation--this can be useful, since the process
can be relatively long.
The default is 0.
