# `sha1` Function
|
|
|
|
`sha1` computes the SHA1 hash of a given string and encodes it with
|
|
hexadecimal digits.
|
|
|
|
The given string is first encoded as UTF-8 and then the SHA1 algorithm is applied
|
|
as defined in [RFC 3174](https://tools.ietf.org/html/rfc3174). The raw hash is
|
|
then encoded to lowercase hexadecimal digits before returning.
|
|
|
|
Collision attacks have been successfully performed against this hashing
|
|
function. Before using this function for anything security-sensitive, review
|
|
relevant literature to understand the security implications.
|
|
|
|
## Examples
|
|
|
|
```
|
|
> sha1("hello world")
|
|
2aae6c35c94fcfb415dbe95f408b9ce91ee846ed
|
|
```

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