java.security.interfaces.DSAKeyPairGenerator |
The interface for key generators that can generate DSA key pairs.
Public Methods | |||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|
Initializes this generator with the prime (
p ), subprime (q ), and base (g ) values from the specified parameters. | |||||||||||
Initializes this generator for the specified modulus length.

Initializes this generator with the prime (p
), subprime (q
), and base (g
) values from the specified parameters.
params | the parameter values. |

random | the source of randomness. |
InvalidParameterException | if the specified parameter values are null or
invalid.

Initializes this generator for the specified modulus length. Valid values for the modulus length are the multiples of 8 between 512 and 1024.
The parameter genParams
specifies whether this method should
generate new prime (p
), subprime (q
), and base (g
)
values or whether
it will use the pre-calculated values for the specified modulus
length. Default parameters are available for modulus lengths of 512 and 1024
bits.
modlen | the length of the modulus in bits. |
---|---|
genParams | whether new values should be generated. |
random | the source of randomness. |
InvalidParameterException | if the specified modulus length is not valid, or if there are
no pre-calculated values and genParams is false .
