int AuthtypeFromName (  const char *  authtype  )

Get authe type id from string literal. Parameters: *authtype  string literal of authtype Returns: auth type id

uint16_t extractKeyLen (  const char *  alg  )

Extract key length from algorithm name saved in folowing form: alg_name:n where: alg_name - descriptive name of the algorithm n - integer value representing key length Useful for variable key length encryption algorithms. Parameters: *alg  string literal in form "alg_name:n" Returns: integer value of n (key length)

const struct IdTypeConfigItem* GetAvailableIdTypes (  void   )

Get pointer to the array contaning list of the available ID types. Returns: pointer to the array contaning list of available ID types

const struct TransformConfigItem* GetAvailableTransformsTypes (  void   )

Get pointer to the array containing list of the available transforms types. Returns: pointer to available transforms types

const char* GetTransformName (  int  type, int  alg )

Get human readable transform type string. The outut of this function is in format "%s/%s", where first part is transform type, and second part is used algorithm. Parameters: type  transform type alg  used algorithm Returns: pointer to the static buffer which contains human readable transform type string

int IdTypeFromName (  const char *  name  )

Get type id from name string , useful in configuration. Parameters: name  string idtype name Returns: -1 if fail,id on success;

int TransformFromName (  const char *  name, uint8_t  type, uint8_t *  id, uint16_t *  keylen )

Get transform id from string, useful in configuration. Parameters: name  string transform name type  transform type (IKEv2_TRT_...) id  returned transform id keylen  result ptr for key length Returns: 0 if succes, -1 if fail
