int EncrKeyLenValid (  uint32_t  type, uint32_t  keylen )

Check for valid key length. Parameters: type  encryption algorithm keylen  encryption algorithm key length in bites Returns: 0 on success, 1 otherwise

uint32_t GetEncrBlockLen (  uint32_t  type, uint32_t  keylen )  [inline]

Get length of block for specific encryption algorithm. Parameters: type  type of the encryption algorithm keylen  key length of encryption algorithm (optional) Returns: block length of encryption algorithm

uint32_t GetEncrKeyLen (  uint32_t  type, uint16_t  keylen )  [inline]

Get encryption key length. Parameters: type  type of encryption algorithm keylen  key length in bites (optional) Returns: the key len of crypto algo in bytes

void IKEv2Crypt (  uint8_t *  data, uint32_t  dlen, uint8_t *  iv, uint8_t *  key, uint32_t  type, uint32_t  keylen, int  enc )

Encrypt/decrypt a block of data. Parameters: *data  ptr to src buffer = dst buffer dlen  len of data (length should be a multiple of block len) *iv  initialization vector *key  key for cipher type  type of crypt algo keylen  key length parameter (optional) enc  IKEv2_ENCRYPT for encryption, IKEv2_DECRYPT for decryption
