rhash
Calculate or check common message digests.
TLDR
Calculate default CRC32 digests of a file
$ rhash [path/to/file]
Recursively process a directory to generate an SFV file using SHA1
$ rhash --sha1 --recursive [path/to/folder] > [path/to/output.sfv]
Verify the integrity of files based on an SFV file
$ rhash --check [path/to/file.sfv]
Calculate the SHA3 digest of a text message
$ rhash --sha3-256 --message '[message]'
Calculate CRC32 digest of a file and output digest encoded in base64 using BSD format
$ rhash --base64 --bsd [path/to/file]
Use custom output template
$ rhash --printf '[%p\t%s\t%{mtime}\t%m\n]' [path/to/file]
