Sets whether or not a public salt should be randomly generated and used to compute a hash if a
{@link HashRequest} does not specify a salt.
<p/>
The default value is {@code false} but should definitely be set to {@code true} if the
{@code HashService} instance is being used for password hashing.
<p/>
<b>NOTE:</b> this property only has an effect if a {@link #getPrivateSalt() privateSalt} is NOT configured. If a
private salt has been configured and a request does not provide a salt, a random salt will always be generated
to protect the integrity of the private salt (without a public salt, the private salt would be exposed as-is,
which is undesirable).
@param generatePublicSalt whether or not a public salt should be randomly generated and used to compute a hash
if a {@link HashRequest} does not specify a salt.
