var cipher = new ZipCrypto();
cipher.InitCipher(Password);
// Decrypt the header. This has a side effect of "further initializing the
// encryption keys" in the traditional zip encryption.
byte[] DecryptedMessage = cipher.DecryptMessage(EncryptedMessage);
Step 1 - Initializing the encryption keys
-----------------------------------------
Start with these keys:
Key(0) := 305419896 (0x12345678)
Key(1) := 591751049 (0x23456789)
Key(2) := 878082192 (0x34567890)
Then, initialize the keys with a password:
loop for i from 0 to length(password)-1
update_keys(password(i))
end loop
Where update_keys() is defined as:
update_keys(char):
Key(0) := crc32(key(0),char)
Key(1) := Key(1) + (Key(0) bitwiseAND 000000ffH)
Key(1) := Key(1) * 134775813 + 1
Key(2) := crc32(key(2),key(1) rightshift 24)
end update_keys
Where crc32(old_crc,char) is a routine that given a CRC value and a
character, returns an updated CRC value after applying the CRC-32
algorithm described elsewhere in this document.
