Digestify

digest·​i·​fy -| _ˈdī-ˌjest-ə-ˌfī

noun - A 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.

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

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 0.4.0 Verify a file against a provided digest/hash/checksum.

USAGE: digestify

ARGS: File to verify Digest to compare to, specified as a case-insensitive hexadecimal string

OPTIONS: -h, --help Print help information -V, --version Print version information ```

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