我有一个十六进制格式的文件,我试图用OpenSSL解密。但是,在将文件从十六进制转换回二进制之后,在输入正确的密码之后,我将收到一个bad magic number错误。我尝试用一个简单的文件再现错误,下面是我所采取的步骤:使用密码1234的加密文件:openssl enc -aes-256-cbc -md sha512 -pbkdf2- 浏览11提问于2022-03-04得...

PHP OpenSSL functions openssl_encrypt() and openssl_decrypt() seem to use PKCS5/7 style padding for all symmetric ciphers. Upon this, you can't use them to encrypt using null byte padding or to decrypt null byte padded data. The developers of the wrapper forgot the padding scheme flags.....

PHP lacks a build-in function to encrypt and decrypt large files. `openssl_encrypt()` can be used to encrypt strings, but loading a huge file into memory is a bad idea.So we have to write a userland function doing that. This example uses the symmetric AES-128-CBC algorithm to encrypt...
