"AttacheCase4" is a powerful file/folder encryption software that uses the world's standard encryption algorithm (AES), while focusing on simplicity of appearance and ease of operation for daily use.

It also uses public key cryptography (RSA), which allows encrypted data to be exchanged securely without sending passwords via email, etc., as is the case with AES and other symmetric key cryptography methods.

Encryption takes only three steps. Simply drag and drop the file and enter the password to encrypt it. If you drag and drop a whole folder, it will be combined into one encrypted file (the whole folder will be packed). Note that the data will be compressed during the encryption process, so the file size will be compact.

This is the macOS version of the Windows version of "AttacheCase" that is used by many people. Encrypted files are compatible, and files can be exchanged, encrypted and decrypted between different operating systems.

Release notes:
- Fix the problem where the public and private key generation buttons were not working and the respective files were not being output.
- Fix the problem with macOS Ventura where the dialog to grant permissions to folders under the sandbox no longer appeared and encryption/decryption was canceled.
- Fix the problem in which the window display position and size were not saved and were displayed in the same location each time it was launched.
