The Features of Dark-Fog

Dark-Fog is a file encryption software, with the purpose of securing important files, for save sharing online in cloud storages or on local storages. It offers 4 encryption options with a high security syntax behind it.

🔒 Full Security

🔒 Full Control

🔒 NO AI

Controlled File encrpytion - your key to self-controlled security localy and online

Control

Make your files unuseable to unpermitted forces, secure your files via password-encryption and even additional key-files for max security. Without the proper password and key-file, its impossible to decrypt the files back to their original state.

Security

Do not trust your files to be safe by host providers, make sure they can truly only be used by these who are intended to. Thanks to a encryption syntax that dynamicly encryptes files based on the password and syntaxt-level, your files are safe of any illigal access.

Secure file sharing

Thanks to the files being encrypted by your own control, no matter where you upload and store your files, they can only be used by you, no matter who may get access to them. Mostly with cloud-services and public file-sharing sites getting highjaked again and again, the risk of missuse of your files are higher then never before.

Multiplattform

Easy file access on the go! Secure and access your most important files not only on your Windows Desktop, but also on Android Phone. Dark-Fog is available on Windows PC and Android Phone in a free uncommercial usage version and a premium commercial licensed version.

Easy usage and deployment

Dark-Fog is very easy to use and fast applied to any device. It does not require any special permission except read and writing permission on the local storage of the device.

Safe messaging

One of the additional features of Dark-Fog is the option to read and write encrypted message-files based on the Dark-Fog encryption syntax. This allows to send messages and informations on the go that is truly secured from "man in the middle" attacks. This feature was designed to communicate potential password lists or other critical informations on a safe way.

Unlimited file size processing

This feature allows to process any file size that your operating FAT(File Cluster Formation)-System allows. There is no memory or size limitation to processing.

→

Dark-Fog Level 1 encryption

This feature allows to use the level 1 for encryption of files with the Dark-Fog Syntax. The 1st is an encryption based on the password alone. Depending on the given password, the encryption will be different. It does not include any hash or checksum for the password used for the encrypted file. Makes it impossible to brute-force or to decipher the used encrypt-password.

→

→

Extended message encryption/decryption

This feature allows to use message-expansion Syntax for encrypting and decrypting messages/files. The “DFMex” is an encryption based on the password and message size. Depending on the given password (up to 1024 signs), the message will be split up and filled with random generated letter-signs, making it impossible to read out the text even without a bit-encryption. After the message-expansion, a 2nd layer encryption with DFV3 based on the file size, will be applied. It does not include any hash or checksum for the password used for the encrypted file. Makes it impossible to brute-force or to decipher the used encrypt-password.

→

Single-File processing

This feature allows you to process one file at a time. Assuring minimal system resource usage and functional processing even for low-end system speck devices and systems.

→
