xhash

This Go program uses goroutines to calculate multiple hashes on strings, files and directories. By default it reads from standard input. It can be used as a drop-in replacement for the GNU coreutils when hard-linked as md5sum, etc. and it actually supports the --zero option with --check, unlike the GNU tool. The output format is fully configurable.

Docker image available at ghcr.io/ricardobranco777/xhash:latest

Examples:

• To hash every file in your home directory using both SHA-512 and SHA-256

xhash -r -sha512 -sha256 $HOME

• To hash the /etc/passwd file with all algorithms except MD5 and SHA-1

xhash -all -md5 -sha1 /etc/passwd

• To hash the string "abc" with all algorithms

xhash -all -s "abc"

• To check the hashes in /tmp/hashes.md5

xhash -c /tmp/hashes.md5

• To hash all files specified in /tmp/files.list

xhash -i /tmp/files.list

Output format

The output format is the same as the BSD commands. Use --gnu to use the format used by md5sum.

To use the format used by hashdeep use --size -f '{{range .}}{{.Sum}},{{end}}{{(index . 0).File}}\n'

Requirements

• Go 1.21+
