SecureTask is a powerful tool with which you can entirely automate the process of encryption and deletion of files on your computer.

With several mouse clicks you can encrypt and/or wipe any number of files which can be located in different folders and even on different drives. You can automatically perform various operations either using SecureTask Wizard, or from within main SecureTask window.

A symmetric cryptographic algorithm is a cryptographic algorithm that typically uses a single key for encryption and decryption. Symmetric algorithms can be divided into two categories: stream algorithms and block algorithms (also called stream and block ciphers).

A block cipher is a type of symmetric-key encryption algorithm that transforms a fixed-length block of plaintext data into a block of ciphertext data of the same length. This transformation takes place under the action of a user-provided secret key. Decryption is performed by applying the reverse transformation to the ciphertext block using the same secret key. The fixed length is called the block size. All algorithms used in this program have the block size 64 bits or 128 bits.

Iterated block ciphers encrypt a plaintext block by a process that has several rounds. In each round, the same transformation (also known as a round function) is applied to the data using a subkey. The set of subkeys is usually derived from the user-provided secret key by a special function. The set of subkeys is called the key schedule. The number of rounds in an iterated cipher depends on the desired security level and the consequent trade-off with performance. In most cases, an increased number of rounds will improve the security offered by a block cipher.

The symmetric algorithms available in this program are listed below.
