The data is encrypted in Cipher Block Chaining (CBC) mode, with an initialization vector by default obtained from the gettimeofday(2) function.<br /> <br /> The ICE encryption algorithm allows key lengths of any multiple of 64 bits by specifying the encryption level. Specifying a level greater than 1 allows long passwords, and correspondingly higher security. The drawback is slower encryption.<br /> <br /> This program only uses the lower 7 bits from each character in the password, so the first 10 characters are significant when using levels 0 or 1. For higher levels n, the key size is 64n, so the useful password length will be (64n + 6)/7. Short passwords will be padded out with zeroes.<br /> <br /> == Links ==<br /> * [https://darkside.com.au/ice/icecrypt.html icecrypt homepage]</div>
