SecureFile is an encryption and compression program that allows you to encrypt and decrypt files using symmetric key and asymmetric key mechanism. It creates a self-decryption archive which can be decrypted at the other end without any dependencies. It incorporates powerful Blowfish algorithm and certificate ( public key/ private key ) for the process of encryption and decryption.It supports secure file deleting and backup of encrypted files It compresses and encrypts selected files and produces a self-decryption archive. The encrypted file can be decrypted simply by double clicking the archive with the given password for symmetric key mechanism and no input is necessary for certificate based encryption and decryption. The user needs no installation of any application to decrypt the files.
