QUESTION
I try to make a coremod on 1.12.2 Forge in order to patch some missing stuff in the Lost Cities mod. (Source: https://github.com/McJtyMods/LostCities/blob/1.12/src/main/java/mcjty/lostcities/dimensions/world/lost/BuildingInfo.java)
A friend and I have written this LostCitiesClassTransformer.java:
...ANSWER
Answered 2021-May-03 at 23:39The problem is that you do Type.getInternalName(BuildingInfo.class)
. That's the very class you're trying to transform as it's being loaded, so you created a circular reference by using it in a way that would need it to be loaded. You'll need to hardcode the string "mcjty/lostcities/dimensions/world/lost/BuildingInfo"
there instead.
Also, in "()Lmcjty/lostcities/api/ILostCityBuilding"
, that's supposed to have a semicolon at the end, so change it to "()Lmcjty/lostcities/api/ILostCityBuilding;"
.
Finally, you need to change false
to true
in new MethodInsnNode(INVOKEINTERFACE, Type.getInternalName(ILostCityBuilding.class), "getMinCellars", "()I", false));
, since it is in fact an interface method.

QUESTION
I'm working on a legacy project with a lot of ancient staffs. There're huge numbers of actions which are used really rare. Half a year ago we upgraded from Symfony 2.8 to Symfony 4.4. All worked pretty well until a manager tried to use one of the old action that now returns AccessDeniedException: Access Denied.
I've checked Symfony documentation and all seems pretty straightforward for me.
The documentation says:
Checking to see if a User is Logged In (IS_AUTHENTICATED_FULLY)
If you only want to check if a user is logged in (you don’t care about roles), you have two options. First, if you’ve given every user ROLE_USER, you can check for that role.
There is app/config/security.yml
with the next configuration:

QUESTION
PasswordHasher.HashPassword doesn't use TUser user, but why included in the method signature?
Thanks!
...ANSWER
Answered 2021-Jan-04 at 09:11The PasswordHasher
class implements the interface IPasswordHasher
that defines the method string HashPassword(TUser user, string password)
. As you noticed, PasswordHasher.HashPassword
doesn't use the TUser
, but another implementation could. The PasswordHasher.HashPassword
generates a random salt and uses it to hash the password directly, without any external data except the password. And by looking at it it seems to be a good implementation.
You could build a MyPasswordHasher
that has a different salt for each user AND saves the salt for the password separately from the password. In this case you would need a TUser
object containing the salt. Some years ago on the Security SO it was asked if it was a good idea to calculate the hash as hash(username + password)
... To calculate the hash like that, you would need a TUser
object with the username
(we will ignore the quality of that solution here compared to the Microsoft solution).
Another common implementation I've seen in some sites is to have a column in the User table containing the "version" of "protocol" used for hashing passwords... In this way, if the hashing is discovered to be weak, a new "protocol" can be devised, and this "version" says in which way the hash has been calculated.
So Microsoft programmers implemented the IPasswordHasher
interface to be compatible with this type of hashes. They didn't implement them, but they let open the possibility.
(as a sidenote the Microsoft version of PasswordHasher
generates a "packed" string containing the version, infos on the key derivation function, the salt and the hash all together)

Official Document for How to Read QR code data from Secure QR code of UIDAI Aadhaar card: https://uidai.gov.in/images/resource/User_manulal_QR_Code_15032019.pdf
Have used zxing scanner to scan Secure QR code, And was able to get details of aadhar card with the help of follow project in Github: https://github.com/dimagi/AadharUID
Some how I figured out how to extract photo and bit_indicator_value from converted byte array with the help of instructions on document
But I am unable to get hashed exact hashed value of email and mobile from Secure QR code of Aadhar card byte array to verify
I am bit confused from this line of above mentioned document in page no 6:
- Post getting signature value, check the value of Email_mobile_present_bit_indicator_value:
- if its 3 then first read mobile from index (Byte array length – 1-256) and then email from index (Byte array length – 1- 256- 32) in reverse order. Each value will be of fix size of 32 byte.
- If Email_mobile_present_bit_indicator_value is 1 then only mobile is present.
- If Email_mobile_present_bit_indicator_value is 2 then only email is present.
- If Email_mobile_present_bit_indicator_value is 0 then no mobile or email present.
- Email and Mobile value will available in byte. Convert into Hexadecimal String. .
I have also prepared last step in document page no 6 but the users mobile/email hash value and documents mobile/email byte arrays hash value never matches
Code snippet:
...ANSWER
Answered 2020-Oct-14 at 11:22Just now got the solution, fetched exact mobile and email hash value from byte array
first remove last 256 bytes from byte array then,
if only mobile present then take last 32 bytes from byte array for mobile i.e. (array.length - 32 to array.length)
else if only email present then take last 32 bytes from byte array for email i.e. (array.length - 32 to array.length)
else if both email and mobile present then take last 32 bytes from byte array for mobile, take next last 32 bytes for email i.e. (mobile = array.length - 32 to array.length and email = array.length - 64 to array.length - 32)

Install L96
You can use L96 like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
