使用openssl命令在php服务器上解密文件

Question

I am encrypting a file on client side and trying to decrypt it on my linux server using openssl command, its creating output file but with 0 bytes size.

The code I am using in php for decrypting file is:

system("openssl enc -d -aes-192-ecb -in secure.cxf -out plain.xml -K 11223344556677889900aabbccddeeff0011223344556677");

here I am using AES in ECB mode with 192 bit (24 byte) key,

where

secure.cxf is input file in same folder with php file

plain.xml is output file comes with 0 bytes

11223344556677889900aabbccddeeff0011223344556677 is my private key of decryption

I have tried the same openssl command on different linux operationg systems, the command works fine but on server it makes empty output file. Any idea how to resolve the empty file problem? Is there any alternative way to do same decryption (AES, ECB mode, 192 bit key) for files on php server?

Thanks in advance.

Answer 1

try one of this:

a) create empty file plain.xml and permission to 0666 chmod 0666 plain.xml

or

b) set permission on parent Directory your php file. chmod 0777 DirectoryWithMyFile

You can do this in FTP client or SSH.

Another Way - from phpinfo() find tmp dir and use this dir.

Answer 2

I resolved my problem for decryption by another way using php. If anybody looking for same follow this.
