[Mcrypt-developers] Feat.Req.: File extension embedding

[Andrew <ar...@ng...>]

Hi all,

I have an idea for a possible mcrypt feature: file extension embedding.

That is, when you encrypt a file, the original file extension is removed 
and replaced with '.nc' (presently, '.nc' is added after the original 
extension).

The original extension is then 'embedded' in the encrypted file and 
auto-restored when the file is decrypted.

The goal is thwarting possible attackers, who - knowing the file's 
original extension - could look for signature character sequences that 
are typical of a certain file type (eg. 'JPEG' in jpeg files, etc.)

What do you think? Thanks for listening...
