File Encryptor

Do you have the need to protect your documents from prying eyes? If so, this may be the tool for you!

File Encryptor takes any file and uses a simple, yet effective encryption method to protect your files with the password/encryption key of your choice; simply tell it which file you want to encrypt, enter a password and press encrypt. The file will then be encrypted using XOR encryption and a new, encrypted file will be generated with a .enc extension.

eg myfile.jpg -> myfile.jpg.enc

Decrypting is just as simple, select a .enc file, enter the password and press decrypt; the file will be decrypted and the original restored.

Features

• Quickly encrypts/decrypts files.
• Uses a non standard algorithm.
• Allows you to choose if the original is deleted when the file is encrypted.
• Allows you to choose if the encrypted file is deleted when the file is decrypted.
• Brute force protection (If the password is not correct there is no warning, the output will be garbage.)
• Case sensitive.

Drawbacks

• If you forget your password you may never be able to decrypt your file.
• It may still be possible to use frequency analysis to calculate the password.
• Palindromic passwords will not work. eg. ‘abcba’, ‘ABBA’, ‘glenelg’.
  Passwords such as ‘race car’ and ‘go hang a salami im a lasagna hog’ are fine as they do not reverse perfectly due to spaces.
