DSAGenParameterSpec
DSAGenParameterSpec(
primePLen: Int,
subprimeQLen: Int)
Creates a domain parameter specification for DSA parameter generation using primePLen and subprimeQLen. The value of subprimeQLen is also used as the default length of the domain parameter seed in bits.
| Parameters |
primePLen |
Int: the desired length of the prime P in bits. |
subprimeQLen |
Int: the desired length of the sub-prime Q in bits. |
| Exceptions |
java.lang.IllegalArgumentException |
if primePLen or subprimeQLen is illegal per the specification of FIPS 186-3. |
DSAGenParameterSpec
DSAGenParameterSpec(
primePLen: Int,
subprimeQLen: Int,
seedLen: Int)
Creates a domain parameter specification for DSA parameter generation using primePLen, subprimeQLen, and seedLen.
| Parameters |
primePLen |
Int: the desired length of the prime P in bits. |
subprimeQLen |
Int: the desired length of the sub-prime Q in bits. |
seedLen |
Int: the desired length of the domain parameter seed in bits, shall be equal to or greater than subprimeQLen. |
| Exceptions |
java.lang.IllegalArgumentException |
if primePLenLen, subprimeQLen, or seedLen is illegal per the specification of FIPS 186-3. |
