I realize this was worded poorly. So for my example, in this case, we'd do: test-helper-hash-string "263 410" For SHA-1, we'd get "263 410". For SHA-256, we'd get "313 481" (which, as SHA-256 blobs, both start with "17" in their hex representation). Presumably we'd read some environment variable to determine the proper value. -- brian m. carlson / brian with sandals: Houston, Texas, US https://www.crustytoothpaste.net/~bmc | My opinion only OpenPGP: https://keybase.io/bk2204
