To dump the decrypted file using the given key on stdout, call: |

|

rijndael_decrypt_file('../path/to/file.crypt' , 'mykey'); |
| 9 |
|
| 10 |
Thus, here are the easy instructions: |
| 11 |
|
| 12 |
1) Add a line like the above into this PHP file (not inside these comments, but outside) |
| 13 |
e.g. |
| 14 |
rijndael_decrypt_file('/home/myself/myfile.crypt' , 'MYKEY'); |
| 15 |
|
| 16 |
2) Run this file (and make sure that includes/Rijndael.php is available, if you are moving this file around) |
| 17 |
e.g. |
| 18 |
php /home/myself/example-decrypt.php >output.sql.gz |
| 19 |
|
| 20 |
3) You may then want to gunzip the resulting file to have a standard SQL file. |
| 21 |
e.g. |
| 22 |
gunzip output.sql.gz |
