Used Solid Encryption for Windows?

This encryption utility uses the completely unbreakable OTP algorithm. To provide such safety, however, requires there be as many bits in the key as in the ciphered file. Generating a 1MB key on our PC took 10 minutes. Our main quibble with Solid Encryption is it can't cipher folders or multiple files at once. In addition to files, the program encrypts the Clipboard. A notepad instantly displays the encrypted and decrypted version of your text. Both functions may be useful, for instance, in instant-messaging programs. Besides the basic functions, you can test keys for randomness, the main condition of safety with OTP. The program's primary use may be ciphering very sensitive, but smallish documents for people with high levels of concern for privacy.
