Generate file digest value


The Windows program digestvalue.exe is a freeware command-line program that computes the digest value in base64 encoding for a file or list of files. The base64-encoded digest value is suitable for inserting in the <DigestValue> node of an XML-DSIG document.

For example, to compute the digest value of the file abc.txt using the default algorithm SHA-1:

>digestvalue abc.txt
qZk+NkcGgWq6PiVxeFDCbJzQ2J0=

If you want the more traditional sha1sum and md5sum freeware programs that generate the value in hexadecimal, see our Generate file checksums page.

>digestvalue *.txt
98O8HYCOBHMq32eZZczDTKeuNEE=  123-9.txt
qZk+NkcGgWq6PiVxeFDCbJzQ2J0=  abc.txt
Kq5sNclPz7QV2+lfQIuc6R7oRu0=  hello.txt
iKW4Z8PRECB3huZlI80eSkhNppc=  hellon.txt
Compute the SHA-256 digest.
>digestvalue -2 abc.txt
ungWv48Bz+pBQUDeXa4iI7ADYaOWF3qctBD/YfIAFa0=
Compute the MD5 digest and display in hexadecimal.
>digestvalue -mx abc.txt

Display the help
>digestvalue -h
Usage: digestvalue [-2|-m] [-x] [-h|v] [FILE]...
Compute the digest value for each FILE.
With no file, read standard input.
 -2    use SHA-256 digest algorithm (default=SHA-1)
 -m    use MD5 digest algorithm (default=SHA-1)
 -x    display digest in hex encoding (default=base64)
 -h    display this help and exit
 -v    output version information and exit
