# `md5` Function
-> **Note:** This page is about Terraform 0.12 and later. For Terraform 0.11 and
earlier, see
[0.11 Configuration Language: Interpolation Syntax](../../configuration-0-11/interpolation.html).
`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")

the contents of a file rather than from a string value.
