Creating DLL files for PHP4

>libmcrypt.dll does in fact contain the mcrypt functions, but PHP can't >call these functions directly. Instead you need to use the php_mcrypt.dll >wrapper library, unless the wrapper functions are compiled directly into >the PHP module or executable. Does this indicate to you that I need to include the libmcrypt.dll as an extension or use dl("libmcrypt.dll");? When I try this I still get a warning stating that this may not be a php library, even when I have the php_mcrypt.dll loaded as an extension. I also have tried php_mcrypt.dll from www.php4win.de but I get the following warnings when I try to use the functions: Warning: could not open encryption module in c:\web_development\dmccandless\example.php on line 25 Warning: Supplied argument is not a valid MCrypt resource in c:\web_development\dmccandless\example.php on line 26 Warning: can not create an IV with size 0 or smaller in c:\web_development\dmccandless\example.php on line 26 Warning: Supplied argument is not a valid MCrypt resource in c:\web_development\dmccandless\example.php on line 27 Warning: Supplied argument is not a valid MCrypt resource in c:\web_development\dmccandless\example.php on line 28 Warning: Supplied argument is not a valid MCrypt resource in c:\web_development\dmccandless\example.php on line 29 code snippet (lines 25-29): $td = mcrypt_module_open (MCRYPT_TripleDES, "", MCRYPT_MODE_ECB, ""); $iv = mcrypt_create_iv (mcrypt_enc_get_iv_size ($td), MCRYPT_RAND); mcrypt_generic_init ($td, $key, $iv); $encrypted_data = mcrypt_generic ($td, $input); mcrypt_generic_end ($td); Also, when I use phpinfo(); the mcrypt module states that there are no supported ciphers and no supported modes. I think I must be doing something incorrectly with the setup because there is a keys directory that contains files for the various cipher algorithms, such as tripledes.a.
