B4J Library [Tool] File encryption/decryption

I needed to encrypt and decrypt files in a B4J server project, so since I had to do it anyway, I spent some extra time developing this tool (using B4J, of course).

Only now do I "see" a couple of things I could add:

• Drag & Drop
• Opening the destination folder

What happens if the user forgets the encryption password?

What happens if the user forgets the encryption password?

It depends on the content of the file he encrypted.
He might not care or he might commit suicide, I suppose

Joking aside, I don't suppose you mean the tool should save the password?!

Maybe he means a question like asking your pet's name.

or a technique I have used a few times

a mnemonic acronym or a mnemonic phrase based on the first letters.

For example, with:

“A Red Fox Found A Key Under A Tree And Ran To The Mountain.”

You take the first letter of each word:

A R F F A K U A T A R T T M

And you can transform it into:

ARFFAKUATARTTM7!

Another technique is to keep some words intact and use initials for the others:

RedFox!FKUATTM7

The advantage is that you remember the original phrase, not the string of characters directly.
