<P>Calculate hash values for files.</P>

<H4>Syntax</H4>

<PRE class="syntax">
h [-scrc{Method}] [files]
</PRE>

<P>Supported methods: CRC32, CRC64, SHA1, SHA256, BLAKE2sp. Default method is CRC32.</P>

<H4>Examples</H4>

<P>calculates CRC32 for <SPAN class="filename">a.txt</SPAN>.</P>

<PRE class="example">
7z h -scrcsha256 a.iso
</PRE>

<P>calculates SHA256 for <SPAN class="filename">a.iso</SPAN>.</P>

<P>calculates CRC32 for all files in current folder and all subfolders.</P>

<H4>Notes</H4>

<P>7-Zip shows hash values for each file, the sum of hash values and 
the sum that includes all hash values of data and all hash values for filenames.</P>

<P>7-Zip represents hash values for CRC32 and CRC64 as integer numbers in hex.</P> 
<P>7-Zip represents hash values For SHA1, SHA256 and BLAKE2sp as sequence of bytes in hex.</P>
