/a

algorithm to use, can be one of the following (case sensitive): ENTROPY, CRC32, MD5, SHA1, SHA256, SHA384 or SHA512. Default is SHA256.

Note: Entropy is neither a cryptographic algorithm nor will it produce a checksum

/c

comparison checksum, affects %ERRORLEVEL% (match=0, no match=1)

/e

calculate the "Shannon" entropy of the specified file

/s

Verify the digital signature of the file and display its digital signature information (if available)

/b

Brief output, only displays checksum

/t

Display/guess file type regardless of extension

filename

path to the filename to generate the checksum from
