The raw hash is 16 then encoded to lowercase hexadecimal digits before returning. 17 18 Collision attacks have been successfully performed against this hashing 19 function. Before using this function for anything security-sensitive, review 20 relevant literature to understand the security implications. 21 22 ## Examples 23 24 ```shell-session 25 > sha1("hello world") 26 2aae6c35c94fcfb415dbe95f408b9ce91ee846ed 27 ```
