Data Structures
struct	DsaKey

Typedefs
typedef struct DsaKey	DsaKey

Enumerations
enum	{ DSA_HALF_SIZE = 20, DSA_SIG_SIZE = 40 }

Functions
WOLFSSL_API int	wc_InitDsaKey (DsaKey *key)
	This function initializes a DsaKey object in order to use it for authentication via the Digital Signature Algorithm (DSA). More...
WOLFSSL_API int	wc_InitDsaKey_h (DsaKey *key, void *h)
WOLFSSL_API void	wc_FreeDsaKey (DsaKey *key)
	This function frees a DsaKey object after it has been used. More...
WOLFSSL_API int	wc_DsaSign (const byte *digest, byte *out, DsaKey *key, WC_RNG *rng)
	This function signs the input digest and stores the result in the output buffer, out. More...
WOLFSSL_API int	wc_DsaVerify (const byte *digest, const byte *sig, DsaKey *key, int *answer)
	This function verifies the signature of a digest, given a private key. It stores whether the key properly verifies in the answer parameter, with 1 corresponding to a successful verification, and 0 corresponding to failed verification. More...
WOLFSSL_API int	wc_DsaPublicKeyDecode (const byte *input, word32 *inOutIdx, DsaKey *, word32)
WOLFSSL_API int	wc_DsaPrivateKeyDecode (const byte *input, word32 *inOutIdx, DsaKey *, word32)
WOLFSSL_API int	wc_DsaKeyToDer (DsaKey *key, byte *output, word32 inLen)
	Convert DsaKey key to DER format, write to output (inLen), return bytes written. More...
WOLFSSL_API int	wc_SetDsaPublicKey (byte *output, DsaKey *key, int outLen, int with_header)
WOLFSSL_API int	wc_DsaKeyToPublicDer (DsaKey *key, byte *output, word32 inLen)
WOLFSSL_API int	wc_MakeDsaKey (WC_RNG *rng, DsaKey *dsa)
	Create a DSA key. More...
WOLFSSL_API int	wc_MakeDsaParameters (WC_RNG *rng, int modulus_size, DsaKey *dsa)
	FIPS 186-4 defines valid for modulus_size values as (1024, 160) (2048, 256) (3072, 256) More...
WOLFSSL_API int	wc_DsaImportParamsRaw (DsaKey *dsa, const char *p, const char *q, const char *g)
WOLFSSL_API int	wc_DsaImportParamsRawCheck (DsaKey *dsa, const char *p, const char *q, const char *g, int trusted, WC_RNG *rng)
WOLFSSL_API int	wc_DsaExportParamsRaw (DsaKey *dsa, byte *p, word32 *pSz, byte *q, word32 *qSz, byte *g, word32 *gSz)
WOLFSSL_API int	wc_DsaExportKeyRaw (DsaKey *dsa, byte *x, word32 *xSz, byte *y, word32 *ySz)
