`#include <gfpcrypt.h>`

Inheritance diagram for DSA:

List of all members.

## Detailed Description

DSA

Definition at line 384 of file gfpcrypt.h.

## Public Types
enum | { MIN_PRIME_LENGTH = 1024, MAX_PRIME_LENGTH = 1024, PRIME_LENGTH_MULTIPLE = 64 }
| FIPS 186-2 Change Notice 1 changed the minimum modulus length to 1024.
typedef PK_FinalTemplate< DL_SignerImpl< SchemeOptions > > | Signer
| implements PK_Signer interface
typedef PK_FinalTemplate< DL_VerifierImpl< SchemeOptions > > | Verifier
| implements PK_Verifier interface
## Static Public Member Functions
static const char *__cdecl | StaticAlgorithmName ()
static bool __cdecl | GeneratePrimes (const byte *seed, unsigned int seedLength, int &counter, Integer &p, unsigned int primeLength, Integer &q, bool useInputCounterValue=false)
| Generate DSA primes according to NIST standard.
static bool __cdecl | IsValidPrimeLength (unsigned int pbits)

## Member Function Documentation

bool DSA::GeneratePrimes | ( | const byte * | seed,
|  | unsigned int | seedLength,
|  | int & | counter,
|  | Integer & | p,
|  | unsigned int | primeLength,
|  | Integer & | q,
|  | bool | useInputCounterValue = `false` |
| ) |  |  | `[static]`

Generate DSA primes according to NIST standard.

Both seedLength and primeLength are in bits, but seedLength should be a multiple of 8. If useInputCounterValue == true, the counter parameter is taken as input, otherwise it's used for output
