Gck.Builder.prototype.set_data

function set_data(attr_type: Number(gulong), value: ByteArray): void {
    // Gjs wrapper for gck_builder_set_data()
}
  

Set a new attribute to the builder with an arbitrary value. If an attribute with attr_type already exists in the builder then it is changed to the new value, otherwise an attribute is added.

The memory in value is copied by the builder.

null may be specified for the value argument, in which case an empty attribute is created. GCK_INVALID may be specified for the length, in which case an invalid attribute is created in the PKCS\#11 style.
