Siguiendo el ejemplo de encriptado y desencriptado mostrado por kooktroop , se puede construir las funciones siguientes siendo necesarias la llave y el texto a encriptar o desencriptar, anulando siempre los valores cero al final del reenvío <?php # ecnrypt a text in $texto with the key $llave function encripta($texto) { $llave="chichicaste"; return mcrypt_encrypt(MCRYPT_XTEA, $llave, $texto, MCRYPT_MODE_ECB, mcrypt_create_iv(mcrypt_get_iv_size(MCRYPT_XTEA, MCRYPT_MODE_ECB), MCRYPT_RAND)); } # decrypt a text in $cosa with the key $llave function desencripta($cosa) { $llave="chichicaste"; return rtrim(mcrypt_decrypt(MCRYPT_XTEA, $llave, $cosa, MCRYPT_MODE_ECB, mcrypt_create_iv(mcrypt_get_iv_size(MCRYPT_XTEA, MCRYPT_MODE_ECB), MCRYPT_RAND)), "\0"); } $texto = "one swirl to rule them all"; $variable1 = encripta($texto); $variable2 = desencripta($variable1); echo "texto = " . $texto .
