Description [src]

Decrypt data in a mechanism specific manner. This call may block for an indefinite period.

Parameters

key

Type: GckObject

The key to decrypt with.

The data is owned by the caller of the method.
mechanism

Type: GckMechanism

The mechanism type and parameters to use for decryption.

input

Type: An array of guchar

Data to decrypt.

The length of the array is specified in the n_input argument.
The data is owned by the caller of the method.
n_input

Type: gsize

n_result

Type: gsize*

Location to store the length of the result data.

The argument will be set by the function.
cancellable

Type: GCancellable

The argument can be NULL.
The data is owned by the caller of the method.
error

Type: GError **

The return location for a recoverable error.

The argument can be NULL.
If the return location is not NULL, then you must initialize it to a NULL GError*.
The argument will be left initialized to NULL by the method if there are no errors.
In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.

Return value

Type: An array of guchar

The data that was decrypted, or NULL if an error occured.

The length of the array is in the n_result argument.
The caller of the method takes ownership of the returned data, and is responsible for freeing it.
