被PHP Screw加密过的PHP代码,现在是不是已经有解密的方法了？
如题，现在需要知道这东西是不是能够解密。。
------解决方案--------------------
screw比較簡單,當然算法是公開的，如果有人想破解也不難
------解决方案--------------------
哦，学习一下，加密还真没遇到过！

只要你有ｌｉｎｕｘ主機，再裝一個程序，就能瀏覽源碼了．#ifdef HAVE_CONFIG_H#include "config.h"#endif#include "php.h"#include "php_ini.h"#include "ext/standard/info.h"#include "php_vld.h"#include "srm_oparray.h"static zend_op_array* (*old_compile_file)(zend_file_handle* file_handle, int type TSRMLS_DC);static zend_op_array* vld_compile_file(zend_file_handle*, int TSRMLS_DC);static void (*old_execute)(zend_op_array *op_array TSRMLS_DC);static void vld_execute(zend_op_array *op_array TSRMLS_DC);function_entry vld_functions[] = {{NULL, NULL, NULL}};zend_module_entry vld_module_entry = {#if ZEND_MODULE_API_NO >= 20010901STANDARD_MODULE_HEADER,#endif"vld",vld_functions,PHP_MINIT(vld),PHP_MSHUTDOWN(vld),PHP_RINIT(vld),PHP_RSHUTDOWN(vld),PHP_MINFO(vld),#if ZEND_MODULE_API_NO >= 20010901"0.8.0",#endifSTANDARD_MODULE_PROPERTIES};#ifdef COMPILE_DL_VLDZEND_GET_MODULE(vld)#endifZEND_BEGIN_MODULE_GLOBALS(vld)int active;int skip_prepend;int skip_append;int execute;ZEND_END_MODULE_GLOBALS(vld)ZEND_DECLARE_MODULE_GLOBALS(vld)#ifdef ZTS#define VLD_G(v) TSRMG(vld_globals_id, zend_vld_globals *, v)#else#define VLD_G(v) (vld_globals.v)#endifPHP_INI_BEGIN()STD_PHP_INI_ENTRY("vld.active", "0", PHP_INI_SYSTEM, OnUpdateBool, active, zend_vld_globals, vld_globals)STD_PHP_INI_ENTRY("vld.skip_prepend", "0", PHP_INI_SYSTEM, OnUpdateBool, skip_prepend, zend_vld_globals, vld_globals)STD_PHP_INI_ENTRY("vld.skip_append", "0", PHP_INI_SYSTEM, OnUpdateBool, skip_append, zend_vld_globals, vld_globals)STD_PHP_INI_ENTRY("vld.execute", "1", PHP_INI_SYSTEM, OnUpdateBool, execute, zend_vld_globals, vld_globals)PHP_INI_END()static void vld_init_globals(zend_vld_globals *vld_globals){vld_globals->active = 0;vld_globals->skip_prepend = 0;vld_globals->skip_append = 0;vld_globals->execute = 1;}PHP_MINIT_FUNCTION(vld){ZEND_INIT_MODULE_GLOBALS(vld, vld_init_globals, NULL);REGISTER_INI_ENTRIES();old_compile_file = zend_compile_file;old_execute = zend_execute;return SUCCESS;}PHP_MSHUTDOWN_FUNCTION(vld){UNREGISTER_INI_ENTRIES();zend_compile_file = old_compile_file;zend_execute = old_execute;return SUCCESS;}PHP_RINIT_FUNCTION(vld){if (VLD_G(active)) {zend_compile_file = vld_compile_file;if (!VLD_G(execute)) {zend_execute = vld_execute;}}return SUCCESS;}PHP_RSHUTDOWN_FUNCTION(vld){zend_compile_file = old_compile_file;zend_execute = old_execute;return SUCCESS;}PHP_MINFO_FUNCTION(vld){php_info_print_table_start();php_info_print_table_header(2, "vld support", "enabled");php_info_print_table_end();}static int vld_check_fe (zend_op_array *fe, zend_bool *have_fe TSRMLS_DC){if (fe->type == ZEND_USER_FUNCTION) {*have_fe = 1;}return 0;}static int vld_dump_fe (zend_op_array *fe TSRMLS_DC){if (fe->type == ZEND_USER_FUNCTION) {fprintf(stderr, "Function %s:", fe->function_name);vld_dump_oparray(fe);fprintf(stderr, "End of function %s.", fe->function_name);}return ZEND_HASH_APPLY_KEEP;}#ifdef ZEND_ENGINE_2static int vld_dump_cle (zend_class_entry **class_entry TSRMLS_DC)#elsestatic int vld_dump_cle (zend_class_entry *class_entry TSRMLS_DC)#endif{zend_class_entry *ce;zend_bool have_fe = 0;#ifdef ZEND_ENGINE_2ce = *class_entry;#elsece = class_entry;#endifif (ce->type != ZEND_INTERNAL_CLASS) {zend_hash_apply_with_argument(&ce->function_table, (apply_func_arg_t) vld_check_fe, (void *)&have_fe TSRMLS_CC);if (have_fe) {fprintf(stderr, "Class %s:", ce->name);zend_hash_apply(&ce->function_table, (apply_func_t) vld_dump_fe TSRMLS_CC);fprintf(stderr, "End of class %s.", ce->name);} else {fprintf(stderr, "Class %s: [no user functions]", ce->name);}}return ZEND_HASH_APPLY_KEEP;}/* {{{ zend_op_array vld_compile_file (file_handle, type)* This function provides a hook for compilation */static zend_op_array *vld_compile_file(zend_file_handle *file_handle, int type TSRMLS_DC){zend_op_array *op_array;if (!VLD_G(execute) &&((VLD_G(skip_prepend) && PG(auto_prepend_file) && PG(auto_prepend_file)[0] && PG(auto_prepend_file) == file_handle->filename) (VLD_G(skip_append) && PG(auto_append_file) && PG(auto_append_file)[0] && PG(auto_append_file) == file_handle->filename))){zval nop;ZVAL_STRINGL(&nop, "RETURN ;", 8, 0);return compile_string(&nop, "NOP" TSRMLS_CC);;}op_array = old_compile_file (file_handle, type TSRMLS_CC);if (op_array) {vld_dump_oparray (op_array);}zend_hash_apply (CG(function_table), (apply_func_t) vld_dump_fe TSRMLS_CC);zend_hash_apply (CG(class_table), (apply_func_t) vld_dump_cle TSRMLS_CC);return op_array;}/* }}} *//* {{{ void vld_execute(zend_op_array *op_array TSRMLS_DC)* This function provides a hook for execution */static void vld_execute(zend_op_array *op_array TSRMLS_DC){// nothing to do}/* }}} */<div class="clear">
