Digestify

Command line tool to make verification of digests/checksums/hashes on downloaded files a little easier. Just specity the file and the hash listed on the download host. It will infer the possible digest algorithm(s) from the length. It will succeed

Supported Digests

‡ Yeah, yeah. But some sites still use these

Usage

$ digestify -h
digestify 0.1.0
Verify a file against a digest/checksum/hash.

USAGE:
    digestify <FILE> <DIGEST>

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

ARGS:
    <FILE>      File to verify
    <DIGEST>    Digest to compare to.  Must be specified as a
                hexadecimal string.  Case does not matter.

If a match is found against one of the digest algorithms, the command will succeed. Otherwise, it will fail.
