file-encryption (86 questions tagged)
The process of encrypting individual files on a storage medium and permitting access to the encrypted data only after proper authentication is provided.
As “file encryption” might as well be regarded to be a sub-category of “encryption”, the question arises if we should merge both (making “file-encryption” a synonym of “encryption”).
So, what do you think? Does it make sense to merge the “file-encryption” tag with “encryption”, or should we keep both as seperate tags?
