Hello list,
I am looking into being able to encrypt, symetrically, a file, text, images, hopefully
basically any type of file binary or ascii and save it to disc.
then I need to be able to unencypt it to view it.
I've looked into the Digest::MD5 and Crypt::Blowfish modules a bit.
Ok so here's my questions ::
Is there a way to store some file info in the encrypted file?
(Like Content-type and original name)
For instance say I have a gif encrypted as file1.encrypt.
It would be nice to have a script that could unencypt it, see that
it was a gif and then display it in a browser with the appropriate
headers, IE "Content-type: image/gif\n\n".
Or original file name so you could unencrypt it and write it to file with the
original name?
Any advice on the pros and cons of the different encyption related modules?
Experience, advice , etcc..
I know this will vary betwwen modules but how would I go about handling ascii files vs
binary files?
Sorry if this is too vague, I'm really really new to doing this with entire files.
Any pointers to resources would be appreciated too.
Thanks
Dan
