+ *
+ * Hash functions are widely used in multimedia, from error checking and
+ * concealment to internal regression testing. libavutil has efficient
+ * implementations of a variety of hash functions that may be useful for
+ * FFmpeg and other multimedia applications.
+ *
+ * @{
+ *
+ * @defgroup lavu_hash_generic Generic Hashing API
+ * An abstraction layer for all hash functions supported by libavutil.
+ *
+ * If your application needs to support a wide range of different hash
+ * functions, then the Generic Hashing API is for you. It provides a generic,
+ * reusable API for @ref lavu_hash "all hash functions" implemented in libavutil.
+ * If you just need to use one particular hash function, use the @ref lavu_hash
+ * "individual hash" directly.
+ *
+ * @section Sample Code
+ *
+ * A basic template for using the Generic Hashing API follows:
+ *
+ * @code
+ * struct AVHashContext *ctx = NULL;
+ * const char *hash_name = NULL;
+ * uint8_t *output_buf = NULL;
+ *
+ * // Select from a string returned by av_hash_names()
+ * hash_name = ...;
+ *
+ * // Allocate a hash context
+ * ret = av_hash_alloc(&ctx, hash_name);
+ * if (ret < 0)
+ *     return ret;
+ *
+ * // Initialize the hash context
+ * av_hash_init(ctx);
+ *
+ * // Update the hash context with data
+ * while (data_left) {
+ *     av_hash_update(ctx, data, size);
+ * }
+ *
+ * // Now we have no more data, so it is time to finalize the hash and get the
+ * // output. But we need to first allocate an output buffer. Note that you can
+ * // use any memory allocation function, including malloc(), not just
+ * // av_malloc().
+ * output_buf = av_malloc(av_hash_get_size(ctx));
+ * if (!output_buf)
+ *     return AVERROR(ENOMEM);
+ *
+ * // Finalize the hash context.
+ * // You can use any of the av_hash_final*() functions provided, for other
+ * // output formats. If you do so, be sure to adjust the memory allocation
+ * // above. See the function documentation below for the exact amount of extra
+ * // memory needed.
+ * av_hash_final(ctx, output_buffer);
+ *
+ * // Free the context
+ * av_hash_freep(&ctx);
+ * @endcode
+ *
+ * @section Hash Function-Specific Information
+ * If the CRC32 hash is selected, the #AV_CRC_32_IEEE polynomial will be
+ * used.
