| # `sha256` Function |
| |
| `sha256` computes the SHA256 hash of a given string and encodes it with |
| hexadecimal digits. |
| |
| The given string is first encoded as UTF-8 and then the SHA256 algorithm is applied |
| as defined in [RFC 4634](https://tools.ietf.org/html/rfc4634). The raw hash is |
| then encoded to lowercase hexadecimal digits before returning. |
| |
| ## Examples |
| |
| ``` |
| > sha256("hello world") |
| b94d27b9934d3e08a52e52d7da7dabfac484efe37a5380ee9088f7ace2efcde9 |
| ``` |

| * [`filesha256`](/terraform/language/functions/filesha256) calculates the same hash from |
| the contents of a file rather than from a string value. |
| * [`base64sha256`](/terraform/language/functions/base64sha256) calculates the same hash but returns |
| the result in a more-compact Base64 encoding. |
