Digestify

digest·​i·​fy -| _ˈdī-ˌjest-ə-ˌfī

verb - Portmanteau of digest and verify. Compute a digest of a file and verify that the digest matches a provided value.

noun - 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's process exit code will be indicate whether the digest matches.

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

Usage

``` $ digestify -h digestify 0.2.1 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.
