CrococryptMirror 1.43

CrococryptMirror (aka "Crococrypt") is an encryption tool which mirrors complete folders to encrypted folders. The encryption algorithms that are used are AES and Twofish (256 bits, cascading). The keyfile is secured by a password using PKCS #5 (PBKDF2) with a SHA512/Whirlpool based HMAC using 100000 iterations and also AES and Twofish.

Additionally, a ZIP compression for storage space optimization is used. For reasons of performance the synchronization of source and destination folder is done in the background.

A backup copy of the keyfiles has to be stored at a secure place. Without the keyfile the containers cannot be decrypted.

In the portable version of CrococryptMirror keyfile and settings are stored together with the application folder. Hence, the complete application can be transported on an external storage device. Moreover, the folder "container" can be used to store portable containers.

Mirroring can be done manually (on-demand) or by using the sync service which detects directory changes on the fly.

Features

• Copying and synchronizing of files/folders/directories (recursive) to encrypted folders
• Encryption of filenames
• Source folders can be stored in multiple destination containers at the same time (e.g., USB disk drive and Cloud storage)
• Network drives can be used as sources and destinations
• Explorer view to read encrypted containers

Use Cases

Some use case and feature examples:

Encrypted Cloud backup

Mirroring of folders on your computer into your cloud storage folder in encrypted form.

Encrypted backup on USB drive

Mirroring of folders on your computer to an external storage device in encrypted form.

Encrypted multi-backup

Multiple storage locations can be used in parallel, e.g., an USB drive, Cloud storage and a local NAS. When using the sync service all encryption destinations while be queued and processed sequentially.
