Alisdair McDiarmid	a4f5e04066	lang/funcs: Add support for OpenSSH RSA key format ... Previously this function only supported the x509 RSA private key format. More recent versions of OpenSSH default to generating a new PEM key format, which this commit now supports using the x/crypto/ssh package. Also improve the returned error messages for various invalid ciphertext or invalid private key errors.	6 years ago
Lars Eric Scheidler	aa07806bfc	lang/funcs: New "uuidv5" function ... This generates name-based uuids, rather than pseudorandom uuids as with the "uuid" function.	7 years ago
Brian Flad	81bdaa8c38	lang/funcs: Fix filebase64sha256 function hashing algorithm ... Reference: https://github.com/hashicorp/terraform/issues/20652 The implementation and testing were incorrectly referencing SHA-512 instead of SHA-256.	7 years ago
Martin Atkins	954d38e870	lang: New file-hashing functions ... In prior versions, we recommended using hash functions in conjunction with the file function as an idiom for detecting changes to upstream blobs without fetching and comparing the whole blob. That approach relied on us being able to return raw binary data from file(...). Since Terraform strings pass through intermediate representations that are not binary-safe (e.g. the JSON state), there was a risk of string corruption in prior versions which we have avoided for 0.12 by requiring that file(...) be used only with UTF-8 text files. The specific case of returning a string and immediately passing it into another function was not actually subject to that corruption risk, since the HIL interpreter would just pass the string through verbatim, but this is still now forbidden as a result of the stricter handling of file(...). To avoid breaking these use-cases, here we introduce variants of the hash functions a with "file" prefix that take a filename for a disk file to hash rather than hashing the given string directly. The configuration upgrade tool also now includes a rule to detect the documented idiom and rewrite it into a single function call for one of these new functions. This does cause a bit of function sprawl, but that seems preferable to introducing more complex rules for when file(...) can and cannot read binary files, making the behavior of these various functions easier to understand in isolation.	7 years ago
Martin Atkins	ecaaa91da9	lang/funcs: Factor out the various hash function implementations ... These all follow the pattern of creating a hash and converting it to a string using some encoding function, so we can write this implementation only once and parameterize it with a hash factory function and an encoding function. This also includes a new test for the sha512 function, which was previously missing a test and, it turns out, actually computing sha256 instead.	7 years ago

Martin Atkins	129f5fe74d	lang/funcs: port some of Terraform's built-in functions ... These implementations are adaptations of the existing implementations in config/interpolate_funcs.go, updated to work with the cty API. The set of functions chosen here was motivated mainly by what Terraform's existing context tests depend on, so we can get the contexts tests back into good shape before fleshing out the rest of these functions.	8 years ago
