アタッシェケース4 at Mac App Store analyse

"AttacheCase4" is a powerful file/folder encryption software that uses the worlds 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.
