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

Algorithm | Bit
Length | Hexadecimal
Length | :----------------------------------------------------------------: | :--------: | :----------------: | SHA-512 | 512 | 128 SHA-256 | 256 | 64 SHA-1 ‡ | 160 | 40 MD5 ‡ | 128 | 32 CRC-32 ‡ | 32 | 8

‡ 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

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

ARGS: File to verify 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.
