Examples

The rz-hash tool can be used to calculate checksums and has functions of byte streams, files, text strings.

$ rz-hash -h
Usage: rz-hash [-vhBkjLq] [-b S] [-a A] [-c H] [-E A] [-D A] [-s S] [-x S] [-f O] [-t O] [files|-] ...
 -v          Shows version
 -h          Shows this help page
 -           Input read from stdin instead from a file
 -a algo     Hash algorithm to use and you can specify multiple ones by
             appending a comma (example: sha1,md4,md5,sha256)
 -B          Outputs the calculated value for each block
 -b size     Sets the block size
 -c value    Compare calculated value with a given one (hexadecimal)
 -e endian   Sets the endianness (default: 'big' accepted: 'big' or 'little')
 -D algo     Decrypt the given input; use -S to set key and -I to set IV (if needed)
 -E algo     Encrypt the given input; use -S to set key and -I to set IV (if needed)
 -f from     Starts the calculation at given offset
 -t to       Stops the calculation at given offset
 -I iv       Sets the initialization vector (IV)
 -i times    Repeat the calculation N times
 -j          Outputs the result as a JSON structure
 -k          Outputs the calculated value using openssh's randomkey algorithm
 -L          List all algorithms
 -q          Sets quiet mode (use -qq to get only the calculated value)
 -S seed     Sets the seed for -a, use '^' to append it before the input, use '@'
             prefix to load it from a file and '-' from read it
 -K key      Sets the hmac key for -a and the key for -E/-D, use '@' prefix to
             load it from a file and '-' from read it
             from stdin (you can combine them)
 -s string   Input read from a zero-terminated string instead from a file
 -x hex      Input read from a hexadecimal value instead from a file

             All the inputs (besides -s/-x/-c) can be hexadecimal or strings
             if 's:' prefix is specified

To obtain an MD5 hash value of a text string, use the -s option:

$ rz-hash -q -a md5 -s 'hello world'
string: md5: 5eb63bbbe01eeed093cb22bb8f5acdc3

It is possible to calculate hash values for contents of files. But do not attempt to do it for very large files because rz-hash buffers the whole input in memory before computing the hash.

To apply all algorithms known to rz-hash, use all as an algorithm name:

$ rz-hash -a all /bin/ls
