Eet allows one to protect entries of an Eet_File individually. This may be used to ensure data was not tampered or that third party does not read your data.
Functions | |
Eet_Key * | eet_identity_open (const char *certificate_file, const char *private_key_file, Eet_Key_Password_Callback cb) |
Creates an Eet_Key needed for signing an eet file. | |
void | eet_identity_close (Eet_Key *key) |
Close and release all resource used by an Eet_Key. A reference counter prevent it from being freed until all file using it are also closed. | |
Eet_Error | eet_identity_set (Eet_File *ef, Eet_Key *key) |
Sets a key to sign a file. | |
void | eet_identity_print (Eet_Key *key, FILE *out) |
Displays both private and public key of an Eet_Key. | |
Eina_Bool | eet_identity_verify (Eet_File *ef, const char *certificate_file) |
Compares the identify certificate of an eet file against a stored one. | |
const void * | eet_identity_x509 (Eet_File *ef, int *der_length) |
Gets the x509 der certificate associated with an Eet_File. Will return NULL if the file is not signed. | |
const void * | eet_identity_signature (Eet_File *ef, int *signature_length) |
Gets the raw signature associated with an Eet_File. Will return NULL if the file is not signed. | |
const void * | eet_identity_sha1 (Eet_File *ef, int *sha1_length) |
Gets the SHA1 associated with a file. Could be the one used to sign the data or if the data where not signed, it will be the SHA1 of the file. | |
void | eet_identity_certificate_print (const unsigned char *certificate, int der_length, FILE *out) |
Displays the x509 der certificate to out. | |
Typedefs | |
typedef struct _Eet_Key | Eet_Key |
typedef int(* | Eet_Key_Password_Callback )(char *buffer, int size, int rwflag, void *data) |
Callback used to request if needed the password of a private key. |
Typedef Documentation
Opaque handle that defines an identity (also known as key) in Eet's cipher system.
typedef int(* Eet_Key_Password_Callback)(char *buffer, int size, int rwflag, void *data) |
Callback used to request if needed the password of a private key.
- Parameters:
-
buffer the buffer where to store the password. size the maximum password size (size of buffer, including '\0'). rwflag if the buffer is also readable or just writable. data currently unused, may contain some context in future.
- Returns:
1
on success and password was set tobuffer
,0
on failure.

- 1.2.0

void eet_identity_certificate_print | ( | const unsigned char * | certificate, |
int | der_length, | ||
FILE * | out | ||
) |
Displays the x509 der certificate to out.
- Parameters:
-
certificate the x509 certificate to print der_length The length the certificate. out where to print.
- Warning:
- You need to compile signature support in EET.
- Since (EFL) :
- 1.2.0

void eet_identity_close | ( | Eet_Key * | key | ) |
Close and release all resource used by an Eet_Key. A reference counter prevent it from being freed until all file using it are also closed.
- Parameters:
-
key the key handle to close and free resources.
- Since (EFL) :
- 1.2.0

Eet_Key* eet_identity_open | ( | const char * | certificate_file, |
const char * | private_key_file, | ||
Eet_Key_Password_Callback | cb | ||
) |
Creates an Eet_Key needed for signing an eet file.
The certificate should provide the public that match the private key. No verification is done to ensure that.
- Parameters:
-
certificate_file The file where to find the certificate. private_key_file The file that contains the private key. cb Function to callback if password is required to unlock private key.
- Returns:
- A key handle to use, or
NULL
on failure.

void eet_identity_print | ( | Eet_Key * | key, |
FILE * | out | ||
) |
Displays both private and public key of an Eet_Key.
- Parameters:
-
key the handle to print. out where to print.
- Warning:
- You need to compile signature support in EET.
- Since (EFL) :
- 1.2.0
- Since :

Eet_Error eet_identity_set | ( | Eet_File * | ef, |
Eet_Key * | key | ||
) |
Sets a key to sign a file.
- Parameters:
-
ef the file to set the identity. key the key handle to set as identity.
- Returns:
- EET_ERROR_BAD_OBJECT if
ef
is invalid or EET_ERROR_NONE on success.

const void* eet_identity_sha1 | ( | Eet_File * | ef, |
int * | sha1_length | ||
) |
Gets the SHA1 associated with a file. Could be the one used to sign the data or if the data where not signed, it will be the SHA1 of the file.
- Parameters:
-
ef The file handle to query. sha1_length The length of returned data, may be NULL
.
- Returns:
- the associated SHA1 or
NULL
on error.
- Since (EFL) :
- 1.2.0
- Since :
- 3.0
const void* eet_identity_signature | ( | Eet_File * | ef, |
int * | signature_length | ||
) |
Gets the raw signature associated with an Eet_File. Will return NULL if the file is not signed.
- Parameters:
-
ef The file handle to query. signature_length The length of returned data, may be NULL
.
- Returns:
- The raw signature or
NULL
on error.
- Since :
- 3.0
Eina_Bool eet_identity_verify | ( | Eet_File * | ef, |
const char * | certificate_file | ||
) |
Compares the identify certificate of an eet file against a stored one.
- Parameters:
-
ef The file handle to check the identify of certificate_file The path to the certificate file
- Returns:
EINA_TRUE
if the certificates match, otherwiseEINA_FALSE
The ef
file handle mus be valid, and a signed file, otherwise checking will fail. The path to the certificate file must be a valid file path to a 'pem' format file (the same used for siging with eet_identity_open() as a certificate file).
- Note:
- This function can not be used to provide any security mechanism. You need to check your x509 certificate against a chain of trust to have a proper security. This is just a convenience test function.
- Warning:
- You need to compile signature support in EET.

const void* eet_identity_x509 | ( | Eet_File * | ef, |
int * | der_length | ||

- Parameters:
-
ef The file handle to query. der_length The length of returned data, may be NULL
.
- Returns:
- the x509 certificate or
NULL
on error.
