Hi,
I have a system of programs that use mcyrpt routines. The first few times I run through the routine containing mcrypt_create_iv it returns quite quickly, but afterwards, this function can take from 5 to 15 seconds to return. The function wrapping the encryption routines is as follows: $this->cipher = MCRYPT_TripleDES; $this->mcrypt_mode = MCRYPT_MODE_ECB; $this->randomizer = MCRYPT_DEV_RANDOM; function encrypt_and_hex($input) { include '/www/php/key.inc'; $td = mcrypt_module_open ($this->cipher, "", $this->mcrypt_mode, ""); $iv_size = mcrypt_enc_get_iv_size ($td); $iv = mcrypt_create_iv ($iv_size, $this->randomizer); mcrypt_generic_init ($td, $key, $iv); $output = bin2hex(mcrypt_generic ($td, $input)); mcrypt_generic_end ($td); return $output; } I get similar delays in the decryption routine. Any ideas as to why it slows down and/or how to fix it would be appreciated.
