v1.17 (Released 09/04/2021)

Note: v1.17 will be incompatible with 1.16 (and therefore 1.15 and 1.14).

✓ Bug: Red error label shown in main window during successful decryption after selecting incorrect keyfiles
✓ Prevent duplicate keyfile
✓ Add a select keyfile button
✓ Make sure only one of "Fast mode" and "Paranoid mode" can be enabled
✓ (abandoned because this could cause issues with different language characters) Filter invalid charaters and emojis out of "Save as" text entry
✓ Fix bug where metadata says "read-only", but the textbox is modifiable
✓ Add option to delete encrypted files after decryption

v1.16 (Released 08/11/2021)

Fixed bug when entering a wrong password when decrypting a splitted file
Fixed bug where an existing file is delete when a wrong password is used
The password generator is now customizable
Make keyfile support more reliable (keyfile now out of Beta)
Fix keyfile user flow issue
Bug fixes
UI fixes improvements

v1.15 (Released 08/09/2021)

Add cancel button to file shredder and custom number of passes
Password generator
Make password strength circle start at top
Fix shredder UI bugs

v1.14 (Released 08/07/2021)

v1.14 will unfortunately be incompatible with v1.13, as I have dropped Poly1305 in favour of an HMAC. Because I have appended the encryptor version to the encrypted data in v1.13, however, v1.14 and on will be able to tell you which version your data was encrypted with so that you can fetch the correct verion of Picocrypt. There are no security issues in any previous versions of Picocrypt as long as you use a strong password.

Low-severity security fix for the recently discovered partitioning oracle attacks
Move from Monocypher to Go's standard supplemental ChaCha20 in favour of being the latter being stateful
Add SHA3 (normal mode) and BLAKE2b (fast mode) as HMAC to replace Poly1305 and prevent partitioning oracle attacks
Removed ~100 lines of unnecessary code now that Picocrypt uses Go's ChaCha20 (cleaner and stabler code)
Added window icons
Switch to a new Reed-Solomon encoder that automatically corrects errors
Add a "Paranoid mode", which will use the Serpent cipher in addition to XChaCha20
Cleaner code with plenty of comments for people taking a look
Metadata is now Reed-Solomon encoded (everything bit of header data is now RS-encoded for redundancy)
Reed-Solomon checkbox is now enabled and Reed-Solomon works
Implemented Dropbox's zxcvbn password strength checker
Removed paranoid shredding as it is too hard to implement correctly and not cross platform
Fixed Windows zip extract error notice that doesn't appear in 7-Zip (edit: it was a backslash and forwardslash issue)
Optional shred temporary files checkbox
Remove BLAKE3 from the checksum generator tab, as it has no practical use and requires a non-standard library
Advanced options are shown dynamically depending on whether encrypting or decrypting
Window closing disabled during encryption/decryption/shredding to prevent leakage of temporary files
Reduce padding of metadataLength from 10 to 5 (you probably won't type more than 99999 metadata characters)
Use regex to check if an input file is a valid Picocrypt volume or not (during decryption)
Improved user flow as well as fix UI bugs
Code optimizations
Many bug fixes/stability improvments

v1.13 (Released 5/29/2021)

Note: v1.13 will be INCOMPATIBLE with all previous releases! ~~This will likely be the last change in the header format, meaning that all future releases should be compatible with v1.13 and on.~~

Picocrypt has been ported from Python to Go, thus completely rewritten
Added fast mode, which can achieve ~250MB/s
Added file shredder and file checksum generator
Automatically checks for newer versions
Added file chunking support

v1.12.1 (Bug fix patch, released 04/11/2021)

There was a major bug in v1.12 that caused the "Secure wipe" feature to show "Unknown error" when done. This wasn't anything serious security-wise and v1.12.1 has the fix for this bug. Also, a bug that causes "Secure wipe" to hang has been fixed.

v1.12 (Released 04/07/2021)

Beautiful UI
More than x2 as fast as previous versions
Add cancel button to cancel encryption/decryption
(Bug) Delete existing file only if password is correct
Minor aesthetic fixes
Complete rewrite from scratch, to ensure reliability and security
Better anti-corruption (re-defined header format)
Switch to Argon2d instead Argon2id for better security
Switch from SHA3 to BLAKE3 for corruption check
Better user flow

Note: v1.12 will be INCOMPATIBLE with all previous releases!

v1.11 (released 03/23/2021)

Much more secure wipe via sdelete64 for Windows, shred for Linux, and rm -P for MacOS
Much more beautiful UI for MacOS
Robust secure wipe support for drag and dropped files/folders
Only open input files in read mode, since write mode is unnecessary
Clean up source code, add better comments
New: Drag and drop support (multiple files, a folder, a file and a folder, etc.)
