| 5 | To dump the decrypted file using the given key on stdout, call: |
| 6 | |
| 7 | rijndael_decrypt_file( '../path/to/file.crypt' , 'mykey' ); |
| 8 | |
| 9 | Thus, here are the easy instructions: |
| 10 | |
| 11 | 1) Add a line like the above into this PHP file (not inside these comments, but outside) |
| 12 | e.g. |
| 13 | rijndael_decrypt_file( '/home/myself/myfile.crypt' , 'MYKEY' ); |
| 14 | |
| 15 | 2) Run this file (and make sure that includes/Rijndael.php is available, if you are moving this file around) |
| 16 | e.g. |
| 17 | php /home/myself/example-decrypt.php >output.sql.gz |
| 18 | |
| 19 | 3) You may then want to gunzip the resulting file to have a standard SQL file. |
| 20 | e.g. |
| 21 | gunzip output.sql.gz |
