010Editor-keygen

A keygen for 010Editor

1. How does the key generated?

NOTICE: The content of this section is just my suspection. I cannot guarantee that it is absolutely correct because there is no symbol information in 010Editor.exe to confirm my suspection.

There are 3 types of keys (also called passwords in 010Editor) that can activate 010Editor, which are

Key Type	Key Length	Format
Evaluation	19 chars	xxxx-xxxx-xxxx-xxxx
VersionLicense	19 chars	xxxx-xxxx-xxxx-xxxx
TimeLicense	24 chars	xxxx-xxxx-xxxx-xxxx-xxxx

The x in Format column represents a hex char and is case-insensitive if a letter.

Before I explain each kind of keys, there are some concepts I should give.

Daystamp: We know that timestamp is the number of seconds since 00:00:00 Jan. 1st, 1970. Similarly, daystamp is the number of days since Jan. 1st, 1970. For example, the daystamp of Jan. 2nd, 1970 is 1 and Jun. 23th, 2018 is 17705.

Checksum: I'm not sure if it can be called checksum. But I do not have a better word to describe it. Checksum is a 4-bytes-long data and is related with some parameters. You can go to the definition of function _010Editor::Keygen<_010Editor::KeyType::Base>::CalculateChecksum in _010EditorKeygen.hpp to see how to calculate it. The function CalculateChecksum receives 4 parameters. There are

Parameter	Description
utf8_username	The UTF-8 bytes of username that the key licensed to.
IsRegistrationVersion	`false` for `Evaluation` key only. Otherwise it must be `true`.
a3	An unknown parameter. So far it has an unclear meaning.
LicenseCount	It represents how many users can use this license. Must be 1~1000.

EncodedExpireDaystamp: This is a 3-bytes-long data. The function _010Editor::Keygen<_010Editor::KeyType::Base>::EncodeExpireDate in _010EditorKeygen.hpp can calulate it. This function receives 2 parameters. There are

Parameter Description

DaystampOfExpiration The daystamp of expiration. Must be less than 0x1000000.

Seed A parameter used in encoding expire daystamp.
EncodedLicenseCount: This is a 2-bytes-long data. The function _010Editor::Keygen<_010Editor::KeyType::Base>::EncodeLicenseCount in _010EditorKeygen.hpp can calulate it. This function receives only 1 parameter.

Parameter Description

DesiredLicenseCount The license count your want. Must be Must be 1~1000.

Parameter	Description
DaystampOfExpiration	The daystamp of expiration. Must be less than 0x1000000.
Seed	A parameter used in encoding expire daystamp.

Parameter	Description
DesiredLicenseCount	The license count your want. Must be Must be 1~1000.

1.1 Evaluation Key

Evaluation key is generated by 8-bytes-long data. To make it clear, I use

unsigned char data[8];

to represent the 8-bytes-long data.

Evaluation key cannot make your 010Editor become registered version. It can only extend your 010Editor's trial period.

data[4] ~ data[7] are Checksum and calculated by CalculateChecksum function where IsRegistrationVersion = false, a3 = 255 and LicenseCount = 1. utf8_username is based on your input.
data[3] must be 0xFC. It represents the type of key.
data[0] ~ data[2] are EncodedExpireDaystamp and calculated by EncodeExpireDate function where DaystampOfExpiration is based on your input and Seed is Checksum.

Finally, the Evaluation key is the hex string of data[8] where 4 hex chars consist of a block and each block is joined by "-"(hyphen).

1.2 VersionLicense Key

VersionLicense key is also generated by 8-bytes-long data. To make it clear, I use

unsigned char data[8];

to represent the 8-bytes-long data, too.

VersionLicense key can only be used for specified version or the older. And it does not has time limit.

data[4] ~ data[7] are Checksum and calculated by CalculateChecksum function where IsRegistrationVersion = true, a3 = MajorVersion >= 2 ? 0 : MajorVersion. LicenseCount and utf8_username are based on your input.
data[3] must be 0x9C. It represents the type of key.
data[1] ~ data[2] are based on EncodedLicenseCount, data[7] and data[5]. EncodedLicenseCount can be calculated by EncodeLicenseCount function where DesiredLicenseCount is based on your input.
```
data[1] = EncodedLicenseCount.bytes[1] ^ data[7];
data[2] = EncodedLicenseCount.bytes[0] ^ data[5];
```

data[0] is based on MajorVersion and data[6].

data[0] = MajorVersion;
data[0] ^= 0xA7;
data[0] -= 0x3D;
data[0] ^= 0x18;
data[0] ^= Password.data[6];

Finally, the VersionLicense key is the hex string of data[8] where 4 hex chars consist of a block and each block is joined by "-"(hyphen).

1.3 TimeLicense Key

TimeLicense key is generated by 10-bytes-long data which is different to Evaluation and VersionLicense key. To make it clear, I use

unsigned char data[10];

to represent the 10-bytes-long data.

TimeLicense key can be used for any kind of version. But it has time limit.

data[4] ~ data[7] are Checksum and calculated by CalculateChecksum function where IsRegistrationVersion = true, a3 = DaystampOfExpiration. DaystampOfExpiration, LicenseCount and utf8_username are based on your input.
data[0], data[8] ~ data[9] are based on EncodedExpireDaystamp and data[4] ~ data[6]. EncodedExpireDaystamp can be calculated by EncodeExpireDate function where Seed = 0x5B8C27 and DaystampOfExpiration is based on your input.
```
data[0] = EncodedExpireDaystamp.bytes[0] ^ data[6];
data[8] = EncodedExpireDaystamp.bytes[1] ^ data[4];
data[9] = EncodedExpireDaystamp.bytes[2] ^ data[5];
```
data[3] must be 0xAC. It represents the type of key.
data[1] ~ data[2] are based on EncodedLicenseCount, data[7] and data[5]. EncodedLicenseCount can be calculated by EncodeLicenseCount function where DesiredLicenseCount is based on your input.
```
data[1] = EncodedLicenseCount.bytes[1] ^ data[7];
data[2] = EncodedLicenseCount.bytes[0] ^ data[5];
```

Finally, the TimeLicense key is the hex string of data[10] where 4 hex chars consist of a block and each block is joined by "-"(hyphen).
