|

The IceKey class is used for encrypting and decrypting 64-bit blocks of data
|
||||
with the ICE (Information Concealment Engine) encryption algorithm.
|
||||
|
||||
The constructor creates a new IceKey object that can be used to encrypt and decrypt data.
|
||||
The level of encryption determines the size of the key, and hence its speed.
|
||||
Level 0 uses the Thin-ICE variant, which is an 8-round cipher taking an 8-byte key.
|
||||
This is the fastest option, and is generally considered to be at least as secure as DES,
|
||||
although it is not yet certain whether it is as secure as its key size.
|
||||
|
||||
For levels n greater than zero, a 16n-round cipher is used, taking 8n-byte keys.
|
||||
Although not as fast as level 0, these are very very secure.
|
||||
|
||||
Before an IceKey can be used to encrypt data, its key schedule must be set with the set() member function.
|
||||
The length of the key required is determined by the level, as described above.
|
||||
|
||||
The member functions encrypt() and decrypt() encrypt and decrypt respectively data
|
||||
in blocks of eight chracters, using the specified key.
|
||||
|
||||
Two functions keySize() and blockSize() are provided
|
||||
which return the key and block size respectively, measured in bytes.
|
||||
The key size is determined by the level, while the block size is always 8.
|
||||
|
||||
The destructor zeroes out and frees up all memory associated with the key.
