This is not equivalent to `base64encode(sha256("test"))` since `sha256()` 14 returns hexadecimal representation. 15 16 The given string is first encoded as UTF-8 and then the SHA256 algorithm is applied 17 as defined in [RFC 4634](https://tools.ietf.org/html/rfc4634). The raw hash is 18 then encoded with Base64 before returning. Terraform uses the "standard" Base64 19 alphabet as defined in [RFC 4648 section 4](https://tools.ietf.org/html/rfc4648#section-4). 20 21 ## Examples 22 23 ``` 24 > base64sha256("hello world") 25 uU0nuZNNPgilLlLX2n2r+sSE7+N6U4DukIj3rOLvzek= 26 ``` 27 28 ## Related Functions 29 30 * [`filebase64sha256`](./filebase64sha256.html) calculates the same hash from 31 the contents of a file rather than from a string value. 32 * [`sha256`](./sha256.html) calculates the same hash but returns the result 33 in a more-verbose hexadecimal encoding.
