|
Calculates the sha1 hash of <parameter>str</parameter> using the
|
|
<ulink url="&url.rfc;3174">US Secure Hash Algorithm 1</ulink>,
|
|
and returns that hash. The hash is a 40-character hexadecimal number.
|
|
If the optional <parameter>raw_output</parameter> is set to &true;,
|
|
then the sha1 digest is instead returned in raw binary format with a
|
|
length of 20.

|
|
The optional <parameter>raw_output</parameter> parameter was added in
|
|
PHP 5.0.0 and defaults to &false;
