Typedefs

typedef struct _Eet_Key Eet_Key
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.

Detailed Description

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.

Typedef Documentation

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 to buffer, 0 on failure.

Since:

1.2.0

Function Documentation

EAPI void eet_identity_certificate_print (const unsigned char * certificate, int der_length, FILE * out)

Display the x509 der certificate to out. Parameters:

certificate the x509 certificate to print
der_length The length the certificate.
out where to print.

Since:

1.2.0

EAPI void eet_identity_close (Eet_Key * key)

Close and release all ressource used by an Eet_Key. An 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:

1.2.0

EAPI Eet_Key* eet_identity_open (const char * certificate_file, const char * private_key_file, Eet_Key_Password_Callback cb)

Create 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.

Since:

1.2.0

EAPI void eet_identity_print (Eet_Key * key, FILE * out)

Display both private and public key of an Eet_Key. Parameters:

key the handle to print.
out where to print.

Since:

1.2.0

EAPI Eet_Error eet_identity_set (Eet_File * ef, Eet_Key * key)

Set 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.

Since:

1.2.0

EAPI const void* eet_identity_sha1 (Eet_File * ef, int * sha1_length)

Get 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:

1.2.0

EAPI const void* eet_identity_signature (Eet_File * ef, int * signature_length)

Get 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.

EAPI const void* eet_identity_x509 (Eet_File * ef, int * der_length)

Get the x509 der certificate associated with an Eet_File. Will return NULL if the file is not signed.

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.

Since:

1.2.0
