| # `md5` Function |
| |
| `md5` computes the MD5 hash of a given string and encodes it with |
| hexadecimal digits. |
| |
| The given string is first encoded as UTF-8 and then the MD5 algorithm is applied |
| as defined in [RFC 1321](https://tools.ietf.org/html/rfc1321). The raw hash is |
| then encoded to lowercase hexadecimal digits before returning. |
| |
| Before using this function for anything security-sensitive, refer to |
| [RFC 6151](https://tools.ietf.org/html/rfc6151) for updated security |
| considerations applying to the MD5 algorithm. |
| |
| ## Examples |
| |
| ``` |
| > md5("hello world") |
| 5eb63bbbe01eeed093cb22bb8f5acdc3 |
| ``` |
| |

| * [`filemd5`](/language/functions/filemd5) calculates the same hash from |
| the contents of a file rather than from a string value. |
