-functions used in Apache's htpasswd utility.
-The aprsha256 routine returns the identifier {SHA256} plus the base64
+The php_md5 routine is compatible to the PHP md5 function.
+The sha256_hex routine returns a sha256 64-character hexadecimal hash.
+The apr_md5, apr_crypt, apr_sha1 and bcrypt routines are compatible to the
+functions used in Apache’s htpasswd utility.
+The apr_sha256 routine returns the identifier {SHA256} plus the base64
 encoded sha256 hash.
-The sha256 and sha512 functions return glib2's crypt hashes (if supported).
-The validate function validates a password against a hash.

+validate_pw validates a password against a hash.
 
 In win32 environments apr_crypt returns the output of bcrypt, if available.
 If bcrypt is not available, the output of apr_md5 is returned.
