+ * such cases.
+ *
+ * This flag only affects the checks of the compressed data itself; the CRC32
+ * values in the .xz headers will still be verified normally.
+ *
+ * Don't use this flag unless you know what you are doing. Possible reasons
+ * to use this flag:
+ *
+ * - Trying to recover data from a corrupt .xz file.
+ *
+ * - Speeding up decompression, which matters mostly with SHA-256
+ * or with files that have compressed extremely well. It's recommended
+ * to not use this flag for this purpose unless the file integrity is
+ * verified externally in some other way.
+ *
+ * Support for this flag was added in liblzma 5.1.4beta.
