+ *                 calculation, and frees the context.
+ *
+ *                 The SHA-512 result is calculated as

+ *
+ * \deprecated     Superseded by mbedtls_sha512_ret() in 2.7.0
+ *
+ * \param input    The buffer holding the data. This must be a
+ *                 readable buffer of length \p ilen Bytes.
+ * \param ilen     The length of the input data in Bytes.
+ * \param output   The SHA-384 or SHA-512 checksum result. This must
+ *                 be a writable buffer of length \c 64 Bytes.
+ * \param is384    Determines which function to use. This must be either
+ *                 \c 0 for SHA-512, or \c 1 for SHA-384.
+ *
+ * \note           When \c MBEDTLS_SHA512_NO_SHA384 is defined, \p is384 must
