File encryption software for Windows 10.
AttachéCase4 is focusing on using daily, simplicity and simple operability of appearance, is a powerful file / folder encryption software that uses a cryptographic algorithm of the world standard ( AES - Advanced Encryption Standard ).
- Windows10 / NET Framework 4.5 later

Just three steps to the encryption.
Just drag and drop the file, can easily be encrypted. If you drag and drop each folder, combined into one to create an encrypted file.
Because at the time of encryption takes compression to the data, the size will be compact.
Decryption (uncompress) also you could drag-and-drop in, or double-click only to enter a password, you can easily restore to the original file and folder.

Decryption also you can drag and drop files or folders in, and then double-click only to enter a password, you can easily revert to the original file and folder.
In addition, so you can output the encrypted file as executable files, can pass the encrypted file to someone who doesn't have the AttachéCase, that be decrypted.
The encryption algorithm, adopted by the United States government Institute of Standards and Technology NIST in October 2000, has been selected as the next generation encryption standard AES (Advanced Encryption Standard) "Rijndael".
Block length in AES has become a 128-bit fixed, but adopted the specifications of the Rijndael in AttachéCase, key, and block length have become a 256-bit both.
Random number generates an initialization vector (IV), and then encrypted in CBC mode, has been designed to prevent to parsed by anyone.
In the RFC2898, based on the "PKCS # 5 Password-Based Cryptography Specification Version 2.0 (password-based encryption specification)", Random salt (just that salt) is mixed and repeated 1,000 times on password-based key derivation. And outputs a derived key, an initialization vector (IV) in the order. In encryption, it would use both the IV and the key.

I do not accept emails, such as basic questions and how to use.
However, feedback and such as "I would like to demand new feature", "Is not it a bug?", Pull requests are welcome. I hope you'll E-mail, or from on GitHub.
Frequently, the users you who were no longer able to decrypt, (this is often the best) First, please review the password. If there is a reproducibility, I would be great that you could send a data set that shows the reproducibility me.
All free to you, but I have done at their own expense. Thank you for your kind attention to this matter.
If you have a bug report, any demand of additional features, thank you to the Issues on GitHub.
