Description [src]

Unwrap a key from a byte stream. This call may block for an indefinite period.

If attrs is a floating reference, it is consumed.

Parameters

wrapper

Type: GckObject

The key to use for unwrapping.

The data is owned by the caller of the method.

The mechanism to use for unwrapping.

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

Type: An array of guchar

The wrapped data as a byte stream.

The length of the array is specified in the n_input argument.

The length of the wrapped data.

attrs

Type: GckAttributes

Additional attributes for the unwrapped key.

Optional cancellation object, or NULL.

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.
