Functions
const WOLFSSL_EVP_CIPHER *	wolfSSL_EVP_des_ede3_ecb (void)
	Getter functions for the respective WOLFSSL_EVP_CIPHER pointers. wolfSSL_EVP_init() must be called once in the program first to populate these cipher strings. WOLFSSL_DES_ECB macro must be defined for wolfSSL_EVP_des_ede3_ecb(). More...
const WOLFSSL_EVP_CIPHER *	wolfSSL_EVP_des_cbc (void)
	Getter functions for the respective WOLFSSL_EVP_CIPHER pointers. wolfSSL_EVP_init() must be called once in the program first to populate these cipher strings. WOLFSSL_DES_ECB macro must be defined for wolfSSL_EVP_des_ecb(). More...
int	wolfSSL_EVP_DigestInit_ex (WOLFSSL_EVP_MD_CTX *ctx, const WOLFSSL_EVP_MD *type, WOLFSSL_ENGINE *impl)
	Function for initializing WOLFSSL_EVP_MD_CTX. This function is a wrapper for wolfSSL_EVP_DigestInit() because wolfSSL does not use WOLFSSL_ENGINE. More...
int	wolfSSL_EVP_CipherInit_ex (WOLFSSL_EVP_CIPHER_CTX *ctx, const WOLFSSL_EVP_CIPHER *type, WOLFSSL_ENGINE *impl, const unsigned char *key, const unsigned char *iv, int enc)
	Function for initializing WOLFSSL_EVP_CIPHER_CTX. This function is a wrapper for wolfSSL_CipherInit() because wolfSSL does not use WOLFSSL_ENGINE. More...
int	wolfSSL_EVP_EncryptInit_ex (WOLFSSL_EVP_CIPHER_CTX *ctx, const WOLFSSL_EVP_CIPHER *type, WOLFSSL_ENGINE *impl, const unsigned char *key, const unsigned char *iv)
	Function for initializing WOLFSSL_EVP_CIPHER_CTX. This function is a wrapper for wolfSSL_EVP_CipherInit() because wolfSSL does not use WOLFSSL_ENGINE. Sets encrypt flag to be encrypt. More...
int	wolfSSL_EVP_DecryptInit_ex (WOLFSSL_EVP_CIPHER_CTX *ctx, const WOLFSSL_EVP_CIPHER *type, WOLFSSL_ENGINE *impl, const unsigned char *key, const unsigned char *iv)
	Function for initializing WOLFSSL_EVP_CIPHER_CTX. This function is a wrapper for wolfSSL_EVP_CipherInit() because wolfSSL does not use WOLFSSL_ENGINE. Sets encrypt flag to be decrypt. More...
int	wolfSSL_EVP_CipherUpdate (WOLFSSL_EVP_CIPHER_CTX *ctx, unsigned char *out, int *outl, const unsigned char *in, int inl)
	Function for encrypting/decrypting data. In buffer is added to be encrypted or decrypted and out buffer holds the results. outl will be the length of encrypted/decrypted information. More...
int	wolfSSL_EVP_CipherFinal (WOLFSSL_EVP_CIPHER_CTX *ctx, unsigned char *out, int *outl)
	This function performs the final cipher operations adding in padding. If WOLFSSL_EVP_CIPH_NO_PADDING flag is set in WOLFSSL_EVP_CIPHER_CTX structure then 1 is returned and no encryption/decryption is done. If padding flag is seti padding is added and encrypted when ctx is set to encrypt, padding values are checked when set to decrypt. More...
int	wolfSSL_EVP_CIPHER_CTX_set_key_length (WOLFSSL_EVP_CIPHER_CTX *ctx, int keylen)
	Setter function for WOLFSSL_EVP_CIPHER_CTX structure key length. More...
int	wolfSSL_EVP_CIPHER_CTX_block_size (const WOLFSSL_EVP_CIPHER_CTX *ctx)
	This is a getter function for the ctx block size. More...
int	wolfSSL_EVP_CIPHER_block_size (const WOLFSSL_EVP_CIPHER *cipher)
	This is a getter function for the block size of cipher. More...
void	wolfSSL_EVP_CIPHER_CTX_set_flags (WOLFSSL_EVP_CIPHER_CTX *ctx, int flags)
	Setter function for WOLFSSL_EVP_CIPHER_CTX structure. More...
void	wolfSSL_EVP_CIPHER_CTX_clear_flags (WOLFSSL_EVP_CIPHER_CTX *ctx, int flags)
	Clearing function for WOLFSSL_EVP_CIPHER_CTX structure. More...
int	wolfSSL_EVP_CIPHER_CTX_set_padding (WOLFSSL_EVP_CIPHER_CTX *c, int pad)
	Setter function for WOLFSSL_EVP_CIPHER_CTX structure to use padding. More...
unsigned long	wolfSSL_EVP_CIPHER_CTX_flags (const WOLFSSL_EVP_CIPHER_CTX *ctx)
	Getter function for WOLFSSL_EVP_CIPHER_CTX structure. Deprecated v1.1.0. More...
