On my website I host a lot of files, and when people view the site, currently each time the page loads, I have PHP generating the md5 sums for the files right then and there. It was fine when my site was small, but now that's obviously very inefficient. Now I'd like to start generating MD5 sums when a user uploads a file, and storing it in a text file along with other information to be read from there instead.
I know how to incorporate this into my PHP script, however I still have the problem of the hundreds of files that have already been uploaded, that won't have MD5 information stored in their .desc file.
The .desc file already stores certain information such as username, IP, and a file description. I want to append the md5 information to the end of the .desc file. The .dlcnt file is irrelevant, it stores amount of times downloaded.
So basically I'm trying to write a bash script to do this. Trouble is... I know squat about bash scripting!
All I've been able to come up with so far is this:
I'm sure this is a really horribly inefficient way to do this, but it's all I know.
First problem is that a lot of the directories and files have spaces in them. That screws up the script right there. I don't know how to change the names to have a \ in them.
Second problem is I'm not exactly sure how to output the md5sum to the .desc file. Obviously what I have written up there doesn't work, it's not proper use of the variable... but I'm not sure what to do?
Can anyone give me a hand?

DESCRIPTION
The twadmin utility is used to perform certain administrative functions related to Tripwire files and configuration options. Specifically,
twadmin allows encoding, decoding, signing, and verification of Tripwire files, and provides a means to generate and change local and site
keys.
Creating a configuration file (--create-cfgfile)
This command mode designates an existing text file as the new configuration file for Tripwire. The plain text configuration file must be
specified on the command line. Using the site key, the new configuration file is encoded and saved.
Printing a configuration file (--print-cfgfile)
This command mode prints the specified encoded and signed configuration file in clear-text form to standard output.
Replacing a policy file (--create-polfile)
This command mode designates an existing text file as the new policy file for Tripwire. The plain text policy file must be specified on
the command line. Using the site key, the new policy file is encoded and saved.
Printing a policy file (--print-polfile)
This command mode prints the specified encoded and signed policy file in clear-text form to standard output.
Removing encryption from a file (--remove-encryption)
This command mode allows the user to remove signing from signed configuration, policy, database, or report files. Multiple files may be
specified on the command line. The user will need to enter the appropriate local or site keyfile, or both if a combination of files is to
be verified. Even with the cryptographic signing removed, these files will be in a binary encoded (non-human-readable) form.
Encrypting a file (--encrypt)
This command mode allows the user to sign configuration, policy, database files, or reports. Multiple files may be specified on the com-
mand line. The files will be signed using either the site or local key, as appropriate for the type of file. To automate the process, the
passphrase for the key files can be included on the command line.
Examining the signing status of a file (--examine)
This command allows the user to examine the listed files and print a report of their signing status. This report displays the filename,
file type, whether or not a file is signed, and what key (if any) is used to sign it.
Generating keys (--generate-keys)
This command mode generates site and/or local key files with names specified by the user.
Changing passphrases (--change-passphrases)
This command reencrypts the private part of the site and/or local key files using the key filenames and passphrases specified by the user.
