Security utility to encrypt/decrypt user files

Free download

Overview

TACHYON File Cryptor is a security utility that protects the user's personal information from being leaked by encrypting the user's files with the selected encryption algorithm.

Features

Encrypt

  • Max to 100 files encryption.
  • File encryption without size limit.

Decrypt

  • Decrypt max to 100 files using the same key for encrption.
  • File decryption without size limit using the same key for encrption.
  • Decrypt multiple files regardless of encryption algorithm using the same key for encrption.
  • RSA2048 key is processed as a separate file.

Support Drag and Drop

  • Encrypt by selecting single/multiple files and folders.
  • Decrypt by selecting single/multiple files and folders.

Update

  • Automatic software updates

RC4

Stream cipher invented by Ronald Lorin Rivest, encrypts based on octets

※ Software execution speed is faster than bit-level encryption, but there is a vulnerability, so it is not used to encrypt sensitive data.

AES

AES is an encryption method established by the National Institute of Standards and Technology (NIST) in 2001. AES was selected in the competition based on Rijndael, developed by two Belgian cryptographers John Damon and Vincent Lyman.

AES has been used worldwide since it has been adopted by the US government. AES, which replaces DES published in 1977, is a symmetric key algorithm that uses the same key during encryption and decryption.
