FineCrypt allows you to create encrypted self-extracting archives which can be decrypted without it. FineCrypt lets you encrypt files, directories and whole directory trees using a password or a key. It is very easy to use.

10 encryption algorithms

You can choose for encrypting any of 10 encryption algorithms: AES, Blowfish, CAST-256, GOST, IDEA, MARS, RC-6, Serpent, Triple-DES and Twofish; also you can use any of four encryption modes: Electronic Codebook, Cipher Block Chaining, Cipher Feedback and Output Feedback.

The program includes a key manager, the ability to display file statistics, a permanent file wiping function, and integration with the Windows shell.

Creating strongly encrypted file archives

You can encrypt several files either into single encrypted archive or into different encrypted files. With FineCrypt archives you can work in the same way as you work with zip archives: you can add to or remove files from archive , decrypt desired files, and modify file "in-place" not removing it from archive.

Creating encrypted self-extracting executables

With FineCrypt you can create encrypted and non-encrypted self-extracting executable files. You can send such files to people who haven't FineCrypt on theirs computers and they will be able to decrypt this file.

Check for absolute correctness of encryption

FineCrypt is the ONLY encryption program that you can check by yourself for absolute correctness of encryption: how to check FineCrypt.

Encrypting with encryption key or with password

You can provide for the encryption your own encryption key, which will be used for encryption without any further transformation. Most existing encryption products perform the encryption with a key generated from the user's password. The user does not even see the key that is used for encryption of confidential information. FineCrypt makes it possible to perform encryption both with the password and with the key specified by the user.

Secure exchanging encrypted files and encryption keys with other users

FineCrypt Communicator lets you securely communicate with other users of FineCrypt via Internet. Using Communicator you can exchange you encryption keys and encrypted files with other users. Communicator protects your communication with the help of the Public Key Encryption.

Encrypting files and folders with one mouse click

Quick Encrypt feature lets you encrypt files and folders, create encrypted archives and add new files to an existing archive with just one mouse click. Quick Encrypt not only saves your time, but it automatically does for you almost all work with encryption keys. All you need is to specify directory where you store encryption keys. In fact, Quick Encrypt lets you not to care about passwords and encryption keys at all (except of providing physical safety for a media where encryption keys are stored).

Full integration with Windows shell

You can encrypt files in three ways: by choosing Encrypt... from Windows context menu, which appears when you click right mouse button on file or folder; by dragging the file you want to encrypt onto FineCrypt's icon on the desktop; or from main FineCrypt window. You can decrypt files from the Windows Explorer simply by double clicking the left mouse button on the file you want to decrypt; or by dragging encrypted file onto FineCrypt's icon on the desktop.

Statistical analysis

Using the "File statistics" feature you can get the values of some statistic indicators related to the data stored in the file. For example, if you have used a program for file encryption and you cannot test it with the help of test vectors, then you can get an idea about the quality of encryption by analyzing the characteristics of the ciphertext produced by this program. In the main FineCrypt window select a file about which you want to get statistics and after that press Ctrl+Enter or choose menu item File statistics in menu Actions.

Secure deletion of files

Using the "Wipe" utility you can permanently delete the file content so it cannot be retrieved using disk recovery software. You can permanently delete files with the "Wipe" utility in two ways: from the Windows Explorer context menu, or from main FineCrypt window.

Key management

With Key Manager you can easily manage you encryption keys and encrypted files. One of the main requirements that has to be met for encryption is a frequent key change. The number of keys grows rapidly so that the user has to maintain a key database and keep count of what key is used for what file. In FineCrypt for the first time we have used technology developed and patented by Crypto Systems that makes it possible to assign a unique key ID to each key and to store this ID with the file. Thus without any compromise of security there is no need to maintain a separate key database. The keys should be kept in one location and FineCrypt will automatically find the required key before decryption. See for more details: Overview of key management.
