# `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")
|
|

|
|
```

* [`filemd5`](./filemd5.html) calculates the same hash from

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