Solution: Offline Password Reset using One-Time Codes

 Solution: Offline Password Reset using One-Time Codes

1. User Request: When a user forgets their password, they provide their email ID and click on the "forget password" link.

2. Token Generation: The "forget password" link generates a unique token and records it along with the user's email in a "forget password token" table. It also starts a 5-minute timer for this token.

3. User Redirected: The user is then redirected to the "forget password" page and request to enter the token in the token field(to ensure the user).

4. Password Reset: The user uses the one-time reset code to reset their password through a physical interface. (e.g., a dedicated kiosk)

5. User Input: On the "forget password" page, the user is asked to enter their email ID, a new password, and confirm the new password.

6. Token Validation: When the user clicks the submit button, the system checks if the entered email matches any entry in the "forget password token" table.

7. Time Check: If the email is found in the table and the 5-minute timer hasn't expired, the system allows the user to reset their password.

8. Password Reset: If the token is valid and not expired, the user can reset their password.

9. Request for Entry: If the email is not found in the "forget password token" table or the token has expired, the system prompts the user to request a new "forget password" token.

Convert binary to decimal in c using built in function

Image
 Convert binary to decimal in c using built in function     In C, you can use the strtol function from the <stdlib.h> library to convert a binary string to a decimal number. strtol stands for "string to long integer."  Syntax:  long strtol(const char *nptr, char **endptr, int base); nptr : The string you want to convert to a number. endptr : The address of the first character that's not part of the number (if provided). base : The numerical base of the string (e.g., 2 for binary, 10 for decimal).         This code snippet demonstrates converting the binary string "101010" to its decimal equivalent using strtol . The base parameter 2 specifies that the string is in binary format. Adjust the binaryString variable to contain the binary string you want to convert. ```c #include <stdio.h> #include <stdlib.h> int main () { char binaryString [] = "101010" ; long decimal = strtol ( binaryString , NULL...

DFS in Complete Tree

Image
  DFS in Complete Tree  "DFD" typically stands for "Data Flow Diagram." It's a graphical representation used in software engineering and systems analysis to illustrate how data moves through a system. However, it's not an algorithm like BFS or DFS. Completeness: DFDs depict data flow in a system but might not cover every detail, depending on the diagram's level of abstraction. Time & Space Complexity: the time complexity of both DFS and BFS is O(V + E) , where V represents the number of vertices and E represents the number of edges in the graph. And, the space complexity of DFS and BFS is O(V), in the worst case Optimality: DFDs are design tools; their value lies in effectively illustrating data flow for system understanding and analysis, rather than being inherently optimal or non-optimal. Tree:    Code: class Node : def __init__ ( self , value ): self . data = value self . left = None self . right = None...
