+ * Note for using key wrapping:

+ * * The result of the encryption operation is the ciphertext starting
+ * with the 2nd semiblock. The first semiblock is provided as the IV.
+ * The IV used to start the encryption operation is the default IV.
+ *
+ * * The input for the decryption is the first semiblock handed in as an
+ * IV. The ciphertext is the data starting with the 2nd semiblock. The
+ * return code of the decryption operation will be EBADMSG in case an
+ * integrity error occurs.
+ *
+ * To obtain the full result of an encryption as expected by SP800-38F, the
+ * caller must allocate a buffer of plaintext + 8 bytes:
+ *
+ * unsigned int datalen = ptlen + crypto_skcipher_ivsize(tfm);
+ * u8 data[datalen];
+ * u8 *iv = data;
+ * u8 *pt = data + crypto_skcipher_ivsize(tfm);

+ * sg_init_one(&sg, ptdata, ptlen);
+ * skcipher_request_set_crypt(req, &sg, &sg, ptlen, iv);
+ *
+ * ==> After encryption, data now contains full KW result as per SP800-38F.
+ *
+ * In case of decryption, ciphertext now already has the expected length
+ * and must be segmented appropriately:
+ *
+ * unsigned int datalen = CTLEN;
+ * u8 data[datalen];
+ * <ensure that data contains full ciphertext>
+ * u8 *iv = data;
+ * u8 *ct = data + crypto_skcipher_ivsize(tfm);

+ * sg_init_one(&sg, ctdata, ctlen);
+ * skcipher_request_set_crypt(req, &sg, &sg, ptlen, iv);
+ *
+ * ==> After decryption (which hopefully does not return EBADMSG), the ct
+ * pointer now points to the plaintext of size ctlen.
+ *
+ * Note 2: KWP is not implemented as this would defy in-place operation.
+ * If somebody wants to wrap non-aligned data, he should simply pad
