Functions
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...
void	wc_FreeDsaKey (DsaKey *key)
	This function frees a DsaKey object after it has been used. More...
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...
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...
int	wc_DsaPublicKeyDecode (const byte *input, word32 *inOutIdx, DsaKey *key, word32 inSz)
	This function decodes a DER formatted certificate buffer containing a DSA public key, and stores the key in the given DsaKey structure. It also sets the inOutIdx parameter according to the length of the input read. More...
int	wc_DsaPrivateKeyDecode (const byte *input, word32 *inOutIdx, DsaKey *key, word32 inSz)
	This function decodes a DER formatted certificate buffer containing a DSA private key, and stores the key in the given DsaKey structure. It also sets the inOutIdx parameter according to the length of the input read. More...
int	wc_DsaKeyToDer (DsaKey *key, byte *output, word32 inLen)
	Convert DsaKey key to DER format, write to output (inLen), return bytes written. More...
int	wc_MakeDsaKey (WC_RNG *rng, DsaKey *dsa)
	Create a DSA key. More...
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...
