Verifying SHA-256 of a file #3933
-
|
I'm trying to write my first Hurl (version 5.0.1) script to validate a proxy for a MaxMind API proxy.
What I want do to is retrieve the SHA256 file, saved the SHA and then request the actual file and compare checksums. This fails as follows: Basically I can't work out how to resolve this issue to convert the bytes into a string or vice-versa. Thank you in advance for any help! |

Hi @mdodds-cns Unfortunately I don't think we have implemented what you need! We have a decode filter that convert bytes to string given an encoding. But that's not exactly what you want, you want a filter that convert hexadecimal representation string to bytes. What we could do either:
expected_sha256: body regex "([a-f0-9]{64})\\s+[^\\s]+" fromHex
...
sha256 == {{expected_sha256}}
expected_sha256: body regex "([a-f0-9]{64})\\s+[^\\s]+"
...
sha256 toString == {{expected_sha256}}
expected_sha256: body regex "([a-f0-9]{64})\\s+[^\\s]+"
...
sha256 decode "hex" == {{expected_sha256}}I quite like the third solution, as it fits into the As your use case is a rather common use case, I think we're going to address it soon. @fabricereix @lepapareil any preferences? In the meantime, you can still hardcode the GET https://example.org/data.tar.gz

Thanks for investigating this! It does feel like this would be a useful enhancement for Hurl as this is a common pattern when downloading files. |
