rhash

Calculate or check common message digests.

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]
