     8  # `sha1` Function
     9  
    10  `sha1` computes the SHA1 hash of a given string and encodes it with
    11  hexadecimal digits.
    12  
    13  The given string is first encoded as UTF-8 and then the SHA1 algorithm is applied
    14  as defined in [RFC 3174](https://tools.ietf.org/html/rfc3174). The raw hash is
    15  then encoded to lowercase hexadecimal digits before returning.
    16  
    17  Collision attacks have been successfully performed against this hashing
    18  function. Before using this function for anything security-sensitive, review
    19  relevant literature to understand the security implications.
