SHASUM

RFC6234, US Secure Hash Algorithms, defines a number of functions for performing SHA hash functions SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512. Idio provides interfaces to calculate these for strings, files and file descriptors. The default algorithm is SHA256.

dev-null := "/dev/null"

printf "SHA256SUM (%s) = %s\n" dev-null (shasum-file dev-null)
printf "SHA256SUM (\"\")        = %s\n" (shasum-string "")

$ idio simple-shasum
SHA256SUM (/dev/null) = e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855
SHA256SUM ("")        = e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855

Tip

Pass the preferred algorithm as an extra symbol argument, eg.

shasum-file dev-null 'SHA512
