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