v1.13 (Soon to be released)

Note: v1.3 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

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.)
