CryptoUP4.3.1.2

CryptoUP is a reliable program that allows you to encrypt any type of files using powerful algorithms, as well as decode the documents later. The application requires you to provide a minimum 6-character key and allows you to optionally use a key file or a one time pad. Moreover, it allows you to choose between several encryption modes.

Encryption with user-provided key

CryptoUP uses a specific .DLL library, in order to provide you with a powerful method of encrypting files. All you need to do is specify the key, select the input file, then choose a name for the output document. The encoded files cannot be opened unless they are decrypted, with the help of the initial key.Moreover, you can select the level of encryption, by clicking the ‘Swift’ button, until you reach the desired configuration. The information bar at the bottom of the window indicates the level of security and speed of the process: reasonable security (fast), good security (medium), top security (slow).

Several encryption methods

CryptoUP features several alternative methods of encryption, that you can easily switch to. For example, you can choose a method that divides a file into groups of 5 characters, applying encryption or decoding each group individually. Alternatively, you may apply the method which uses Base 64 encoding rules.The OTP method (One Time Pad) implies creating a list of keys, each of which is discarded after a single usage. You need to keep track of which key has already been used for decoding the file. Additionally, you may change the options for the computer’s Floating Point Unit (FPU), from the dedicated menu.

Encryption analysis

CryptoUP offers several tools for calculating the 160-bit hash, as well as creating a report of the character frequency of any selected file. The application comes as a bundle, containing CryptoUP, FindSR, a utility to analyze encrypted files and prime, a command line tool that can compute a list of prime numbers until the specified value.
