### md5
|
||||
|
||||
`md5` hashes the given input and returns its MD5 checksum.
|
||||
|
||||
```html
|
||||
{{ md5 "Hello world, gophers!" }}
|
||||
<!-- returns the string "b3029f756f98f79e7f1b7f1d1f0dd53b" -->
|
||||
```

|

|

```html
|
||||
<img src="https://www.gravatar.com/avatar/{{ md5 "your@email.com" }}?s=100&d=identicon">
|
||||
```
|
||||
|
||||
|
||||
### sha1
|
||||
|
||||
`sha1` hashes the given input and returns its SHA1 checksum.
|
||||
|
||||
```html
|
||||
{{ sha1 "Hello world, gophers!" }}
|
||||
<!-- returns the string "c8b5b0e33d408246e30f53e32b8f7627a7a649d4" -->
