1. Keyword Explanation.

Navicat Activation Public Key
It is a RSA-2048 public key that Navicat used to encrypt or decrypt offline activation information.
It is stored in navicat.exe as a kind of resource called RCData. You can see it by a kind of software Resource Hacker. The concrete content is:
-----BEGIN PUBLIC KEY-----

Request Code
It is a Base64 string that represents 256-bytes-long data, while the 256-bytes-long data is the cipher text of the offline activation information encrypted by Navicat Activation Public Key.
-
Offline Activation Request Information
It is just a JSON-style ASCII string which contains 3 items. Respectively they are
"K"
,"DI"
and"P"
, which represent snKey, checksum (related with your machine and OS), Platform (Appropriately speaking, it should be OS Type).Like:
{"K": "xxxxxxxxxxxxxxxx", "DI": "yyyyyyyyyyyyy", "P": "WIN8"}

Activation Code
It is a Base64 string that represents 256-bytes-long data, while the 256-bytes-long data is the cipher text of the offline activation response information encrypted by Navicat Activation Private Key (so far, we don't know official activation private key).
-
Offline Activation Response Information
Just like Offline Activation Request Information, it is also a JSON-style ASCII string. But it contains 5 items. Respectively they are
"K"
,"N"
,"O"
,"T"
, 'DI
'."K"
and"DI"
has the same meaning mentioned in Offline Activation Request Information and must be same with the corresponding items in Offline Activation Request Information."N"
,"O"
,"T"
represent Name, Organization, Time respectively. Name and Organization are string and the type of Time is unknown."T"
can be omitted. -
snKey
It is a 4-block-long string, while every block is 4-chars-long.
snKey is generated by 10-bytes-long data. In order to explain it easily, I use data[10] to represent the 10-bytes-long data.
-
data[0] and data[1] must be
0x68
and0x2A
respectively.May change when Navicat product changes. Uncertain yet.
-
data[2], data[3] and data[4] can be any byte. Just set them whatever you want.
May change when Navicat product changes. Uncertain yet. But it's very possible right.
-
data[5] and data[6] must be
0xCE
and0x32
respectively.May change when Navicat product changes. Uncertain yet.
-
data[7] represents whether it is commercial license or non-commercial license.
In Navicat 12:
0x65
is commercial license,0x66
is non-commercial license.
In Navicat 11:0x15
is commercial license,0x16
is non-commercial license.May change when Navicat product changes. Uncertain yet.
Must change when version change.
-
High 4 bits of data[8] represents version number. Low 4 bits is unknown, but we can use it to delay activation deadline. Possible value is
0000
or0001
.In Navicat 12: High 4 bits must be
1100
, which is the binary of number12
. In Navicat 11: High 4 bits must be1011
, which is the binary of number11
.Must change when version change.
-
data[9] is unknown, but you can set it
0xFD
or0xFC
or0xFB
if you want to use not-for-resale license.May change when Navicat product changes. Uncertain yet.
After that. Navicat use DES with ECB mode to encrypt the last 8 bytes which are from data[2] to data[9].
The DES key is:
unsigned char DESKey = { 0x64, 0xAD, 0xF3, 0x2F, 0xAE, 0xF2, 0x1A, 0x27 };
Then encode the 10-bytes-long data:
-
Regard data[10] as a 80-bits-long data.
If data[10] starts with
0x68
and0x2A
, so the 80-bits-long data is01011000 00101010......
-
Divide the 80-bits-long data as 16 5-bits-long blocks.
If data[10] starts with
0x68
and0x2A
, so the 80-bits-long data is01011
,00000
,10101
,0....
, ... -
So the value every block is less than 32. Map them by a encode-table:
char EncodeTable[] = "ABCDEFGHIJKLMNOPQRSTUVWXYZ234567";
Then you will get a 16-char-long string.
If data[10] starts with
0x68
and0x2A
, so after encoded, it should starts with"N"
,"A"
,"V"
. -
Divide the 16-char-long string to four 4-chars-long blocks, Then you get snKey.
-
3. Activation Process
-
Check whether sn_Key that user inputs is legal.
-
After user clicks
Activate
, Navicat will start online activation first. If fails, user can choose offline activation. -
Navicat will use the snKey that user inputs and some information collected from user's machine to generate Offline Activation Request Information, then encrypt it by Navicat Activation Public Key and return Base64-encoded string as Request Code.
-
In legal way, the Request Code should be sent to Navicat official activation server by a Internet-accessible computer. And Navicat official activation server will return a legal Activation Code.
But now, we use keygen to play the official activation server's role.
-
According to the Request Code, Get
"DI"
value and"K"
value. -
Fill Offline Activation Response Information with
"K"
value, name, organization name and"DI"
value. -
Encrypt Offline Activation Response Information by Navicat Activation Private Key and you will get 256-byte-long data.
-
Encode 256-byte-long data by Base64. The result is Activation Code.
-
-
Input Activation Code, then offline activation is done.
