  • Recursively: If you want to encrypt and/or decrypt a large set of files individually, this option will tell Picocrypt to go through every recursive file that you drop in and encrypt/decrypt it separately. This is useful, for example, if you are encrypting thousands of large documents and want to be able to decrypt any one of them in particular without having to download and decrypt the entire set of documents. Keep in mind that this is a very complex feature that should only be used if you know what you are doing.
    • +# Caveats +When encrypting multiple files, Picocrypt will automatically zip them into one file before encrypting it. However, this requires a two-step process that creates an unencrypted temporary `.zip.tmp` file in the same destination folder. This has two implications: +
      +
    1. There must be at least double the available free space on the target drive as the combined total size of input files
      2. +
    2. The target drive must be safe to save confidential data; if not, the unencrypted temporary file may be recoverable even after deletion
      3. +
    +To mitigate these caveats, Picocrypt will show info and warning labels accordingly. However, it is best to prevent these issues altogether by always encrypting and decrypting on your main host drive and then copying encrypted volumes to and from external sources, or zipping up input files beforehand and encrypting that single file which doesn't have these caveats. + # Security For more information on how Picocrypt handles cryptography, see Internals for the technical details. If you're worried about the safety of me or this project, let me assure you that this repository won't be hijacked or backdoored. I have 2FA (TOTP) enabled on all accounts with a tie to Picocrypt (GitHub, Reddit, Google, etc.), in addition to full-disk encryption on all of my portable devices. For further hardening, Picocrypt uses my isolated forks of dependencies and I fetch upstream only when I have taken a look at the changes and believe that there aren't any security issues. This means that if a dependency gets hacked or deleted by the author, Picocrypt will be using my fork of it and remain completely unaffected. You can feel confident about using Picocrypt as long as you understand: diff --git a/VERSION b/VERSION index 99dd716..46284af 100644 --- a/VERSION +++ b/VERSION @@ -1 +1 @@ -1.47 +1.48 \ No newline at end of file diff --git a/src/Picocrypt.go b/src/Picocrypt.go index 10baa94..3587e44 100644 --- a/src/Picocrypt.go +++ b/src/Picocrypt.go @@ -2,7 +2,7 @@ package main /* -Picocrypt v1.47 +Picocrypt v1.48 Copyright (c) Evan Su Released under a GNU GPL v3 License https://github.com/Picocrypt/Picocrypt @@ -30,6 +30,7 @@ import ( "os" "path/filepath" "regexp" + "runtime" "strconv" "strings" "time" @@ -60,7 +61,7 @@ var TRANSPARENT = color.RGBA{0x00, 0x00, 0x00, 0x00} // Generic variables var window *giu.MasterWindow -var version = "v1.47" +var version = "v1.48" var dpi float32 var mode string var working bool @@ -131,6 +132,9 @@ var mainStatus = "Ready" var mainStatusColor = WHITE var popupStatus string +var temporaryZip bool +var externalDst bool + // Progress variables var progress float32 var progressInfo string @@ -173,10 +177,117 @@ func (p *compressorProgress) Read(data []byte) (int, error) { return read, err } +var onClickStartButton = func() { + // Start button should be disabled if these conditions are true; don't do anything if so + if (len(keyfiles) == 0 && password == "") || (mode == "encrypt" && password != cpassword) { + return + } + + if keyfile && keyfiles == nil { + mainStatus = "Please select your keyfiles" + mainStatusColor = RED + return + } + tmp, err := strconv.Atoi(splitSize) + if split && (splitSize == "" || tmp <= 0 || err != nil) { + mainStatus = "Invalid chunk size" + mainStatusColor = RED + return + } + + // Check if output file already exists + _, err = os.Stat(outputFile) + + // Check if any split chunks already exist + if split { + names, _ := filepath.Glob(outputFile + ".*") + if len(names) > 0 { + err = nil + } else { + err = os.ErrNotExist + } + } + + // If files already exist, show the overwrite modal + if err == nil && !recursively { + showOverwrite = true + modalId++ + giu.Update() + } else { // Nothing to worry about, start working + showProgress = true + fastDecode = true + canCancel = true + modalId++ + giu.Update() + if !recursively { + go func() { + work() + working = false + showProgress = false + giu.Update() + }() + } else { + // Store variables as they will be cleared + oldPassword := password + oldKeyfile := keyfile + oldKeyfiles := keyfiles + oldKeyfileOrdered := keyfileOrdered + oldKeyfileLabel := keyfileLabel + oldComments := comments + oldParanoid := paranoid + oldReedsolo := reedsolo + oldDeniability := deniability + oldSplit := split + oldSplitSize := splitSize + oldSplitSelected := splitSelected + oldDelete := delete + files := allFiles + go func() { + for _, file := range files { + // Simulate dropping the file + onDrop([]string{file}) + + // Restore variables and options + password = oldPassword + cpassword = oldPassword + keyfile = oldKeyfile + keyfiles = oldKeyfiles + keyfileOrdered = oldKeyfileOrdered + keyfileLabel = oldKeyfileLabel + comments = oldComments + paranoid = oldParanoid + reedsolo = oldReedsolo + deniability = oldDeniability + split = oldSplit + splitSize = oldSplitSize + splitSelected = oldSplitSelected + delete = oldDelete + + work() + if !working { + resetUI() + cancel(nil, nil) + showProgress = false + giu.Update() + return + } + } + working = false + showProgress = false + giu.Update() + }() + } + } +} + // The main user interface func draw() { giu.SingleWindow().Flags(524351).Layout( giu.Custom(func() { + if giu.IsKeyReleased(giu.KeyEnter) { + onClickStartButton() + return + } if showPassgen { giu.PopupModal("Generate password:##"+strconv.Itoa(modalId)).Flags(6).Layout( giu.Row( @@ -499,7 +610,7 @@ func draw() { giu.Checkbox("Paranoid mode", ¶noid), giu.Tooltip("Provides the highest level of security attainable"), giu.Dummy(-170, 0), -
