NAME

     hasher2 -- block based hashing utility

SYNOPSIS

     hasher2 [-hBrv] [-a algorithm] [-b size] [-s string] [-f from] [-t to] [[file] ...]

DESCRIPTION

     This program is part of the radare project.

     Hasher allows you to calculate, check and show the hash values of each block of a target file. The block size is 32768 bytes by default. It's
     allowed to hash from stdin using '-' as a target file.

     You can hash big files by hashing each block and later determine what part of it has been modified. Useful for filesystem analysis.

     This command can be used to calculate hashes of a certain part of a file or a command line passed string.

     This is the command used by the '#' command of radare.

     -a algo	 Select an algorithm for the hashing. Valid values are md5, crc32 and sha1

     -b block size
		 Define the block size

     -B 	 Show per-block hash

     -s string	 Hash this string instead of using the 'source' and 'hash-file' arguments.

     -f from	 Start hashing at given address

     -t to	 Stop hashing at given address

     -r 	 Show output in radare commands

     -v 	 Show version information

     -h 	 Show usage help message.
