In this technique, a plaintext is paired with random, secret key (or pad). In cryptography, a one-time pad ( OTP) is an encryption technique that cannot be cracked if used correctly. ![]() It's probably fine for general use as long as the NSA isn't after you, but if you have the option to install additional software I'd go with TrueCrypt. As it's a closed-source application and I can't find any info about their implementation, I really can't say anything about it. On the other hand they say a new 2.0 feature is "Edit documents stored in “vault”", so maybe they found away around that, though any method that comes to mind either requires administrative privileges or is really hacky.Īs for the security of the actual encryption, 128bit AES is perfectly secure, assuming it's used correctly. This is fine for securing files against loss of the stick, but forces you take them out of the vault to access them, thereby creating unencrypted copies each time. The usual issue with these tools is that you can only store/retrieve files in the "vault", but not open them while inside. ![]() I haven't personally used it, so I can only guess based on the description.
