每年 5 月 7 日,全球組織都會提醒使用者強程式碼的重要性。根據科技巨頭谷歌的說法;
他們的終端使用者中有24%將單字"password"或"Qwerty"作為他們的帳號密碼。
雖然,只有34%的使用者經常更改他們的帳號密碼。
在當今這個技術先進的世界中,每次登入嘗試都有可能遭受網路犯罪攻擊。但現在許多人仍然在其專業和個人帳戶中使用弱密碼。
在這裡,我們將討論和檢查所建立的密碼是非常弱、弱、中等、強還是非常強。為此,我們將按照演算法的要求來檢查密碼的建立標準。在今天的文章中,我們將學習如何使用C 程式碼建立一個強密碼建議器。
這是一個強密碼的通用演算法。它可協助開發者在C 環境中開發密碼建議系統,並找到密碼的特定標準。
步驟 1 − 開始
#步驟 2 - 理想密碼的長度應至少為八個字元。
步驟 3 − 必須包含至少一個數字字元。
第四步 - 至少應該要有一個小寫字母。 [範例:a,b,c.....,z]
第五步 - 至少應該有一個大寫字母。 [例:A,B,C......,Z]
步驟 6 − 它應該包含至少一個特殊字元。 [範例:!@#$ %^&*()- ]
第 7 步 - 結束
switch (k) { case 1: if ((count_alphabet == 7) && (count_number == 0 || count_ALPHABET == 0 || count_ALPHABET == 7 || count_s_symbol == 0)) break; key = getKey(); password = password + alphabet[key]; count_alphabet++; count++; break; case 2: if ((count_ALPHABET == 7) && (count_number == 0 || count_alphabet == 0 || count_alphabet == 5 || count_s_symbol == 0)) break; key = getKey(); password = password + ALPHABET[key]; count_ALPHABET++; count++; break; case 3: if ((count_number == 7) && (count_alphabet == 0 || count_alphabet == 1 || count_ALPHABET == 3 || count_ALPHABET == 0 || count_s_symbol == 0)) break; key = getKey(); key = key % 10; password = password + number[key]; count_number++; count++; break; case 4: if ((count_s_symbol == 1) && (count_alphabet == 0 || count_alphabet == 1 || count_ALPHABET == 0 || count_ALPHABET == 1 || count_number == 0)) break; key = getKey(); key = key % 6; password = password + s_symbol[key]; count_s_symbol++; count++; break; } cout << "\n-----------------------------\n"; cout << " Enter The Password \n"; cout << "------------------------------\n\n"; cout << " " << password add here; cout << "\n\n Press any key continue \n"; getchar(); }
在這個語法中,條件檢查了一個理想密碼的最低要求。我們將每個可能的條件分為四種情況,檢查是否滿足了字母、數字和特殊符號字元的要求,以及是否滿足了最低要求。在處理過程中,如果還有其他字元剩下,那麼它將會被忽略。
方法 1 - 建立強密碼建議環境
方法 2 - 檢查密碼是強、弱還是中
#方法三 - 檢查密碼是否符合條件
在此 C 建構程式碼中,系統將檢查輸入資料(密碼)的強度。它將掃描輸入以查找理想密碼的所有提到的標準。如果所有條件都匹配,那麼它就是一個理想的密碼。否則,輸入中缺少任何字符,它將返回一些隨機生成的密碼。
#include <bits/stdc++.h> using namespace std; string add_more_char(string str, int need){ int pos = 0; string low_case = "abcdefghijklmno"; for (int a = 0; a < need; a++) { pos = rand() % str.length(); str.insert(pos, 1, low_case[rand() % 26]); } return str; } string suggester(int m, int o, int a, int d, string str) { string num = "0123456789"; string low_case = "abcdefghijklmno"; string up_case = "ABCDEFGHIJKLMNO"; string spl_char = "@#$_()!*&%#+-=.`"; int pos = 0; if (m == 0) { pos = rand() % str.length(); str.insert(pos, 1, low_case[rand() % 26]); } if (o == 0) { pos = rand() % str.length(); str.insert(pos, 1, up_case[rand() % 26]); } if (a == 0) { pos = rand() % str.length(); str.insert(pos, 1, num[rand() % 10]); } if (d == 0) { pos = rand() % str.length(); str.insert(pos, 1, spl_char[rand() % 7]); } return str; } void generate_password(int n, string p){ int l = 0, u = 0, d = 0, s = 0, need = 0; string suggest; for (int j = 0; j < n; j++) { if (p[j] >= 97 && p[j] <= 122) l = 1; else if (p[j] >= 65 && p[j] <= 90) u = 1; else if (p[j] >= 48 && p[j] <= 57) d = 1; else s = 1; } if ((l + u + d + s) == 4) { cout << "Hurra! Your Passcode Is Strong, Go Ahead!" << endl; return; } else cout << "Suggested password As Per The Input. Pick One For You! " << endl; for (int i = 0; i < 10; i++) { suggest = suggester(l, u, d, s, p); need = 8 - suggest.length(); if (need > 0) suggest = add_more_char(suggest, need); cout << suggest << endl; } } int main(){ string input_string = "abonirudra@1607"; srand(time(NULL)); generate_password(input_string.length(), input_string); return 0; }
Suggested password As Per The Input. Pick One For You! abonirudGra@1607 abConirudra@1607 abonirudra@1E607 abonirudra@16A07 abonirudra@160L7 abNonirudra@1607 aNbonirudra@1607 abonirDudra@1607 aboniruFdra@1607 abonirNudra@1607
根據上述演算法和C 建立程式碼;編碼字串檢查輸入強度。當滿足所有條件時,整個方法會傳回“Strong”作為輸出。如果僅滿足前三個步驟並且密碼長度至少為八個字符,則它將返回“中等”。
#include <bits/stdc++.h> using namespace std; void printStrongNess(string& input) { int n = input.length(); bool hasLower = false, hasUpper = false; bool hasDigit = false, specialChar = false; string normalChars = "abcdefghijklmnopqrstu" "vwxyzABCDEFGHIJKL023456789 "; for (int i = 0; i < n; i++) { if (islower(input[i])) hasLower = true; if (isupper(input[i])) hasUpper = true; if (isdigit(input[i])) hasDigit = true; size_t special = input.find_first_not_of(normalChars); if (special != string::npos) specialChar = true; } cout << "Strength of password:-"; if (hasLower && hasUpper && hasDigit && specialChar && (n >= 8)) cout << "Strong" << endl; else if ((hasLower || hasUpper) && specialChar && (n >= 6)) cout << "Moderate" << endl; else cout << "Weak" << endl; } int main(){ string input = "Abonirudra@22052023"; printStrongNess(input); return 0; }
Strength of password:-Strong
在這段程式碼中,我們將對特定密碼進行驗證操作。以下是具體的步驟 -
接受使用者的輸入。
現在將檢查使用者輸入的密碼組合。
密碼分為強、中、弱三種。
如果所有條件都為真,則它將是一個強密碼。
其他情況下,中等或弱。
#include <bits/stdc++.h> using namespace std; void checkpassword(string& password) { int n = password.length(); bool hasLower = false, hasUpper = false, hasDigit = false; for (int i = 0; i < n; i++) { if (islower(password[i])) hasLower = true; if (isupper(password[i])) hasUpper = true; if (isdigit(password[i])) hasDigit = true; } cout << "Strength of password you have entered as per the input :-"; if ( hasUpper && hasDigit && hasLower && (n >= 6)) cout << "Strong" << endl; else if ((hasLower || hasUpper) && hasDigit && (n >=6)) cout << "Moderate" << endl; else cout << "Weak" << endl; } int main() { cout << "Welcome To The Password Tester! Let's Check Your Password. " << endl; cout << "Let's consider the average length of an ideal strong password should be more than 6 character " << endl; cout << "Please enter your desired password with :- " << endl; cout << " * at least one upper case letter and lower case letter " << endl; cout << " * and also need to have at least one digit " << endl; string password; cout <<"Enter your monermoto password"<<endl; getline(cin,password); checkpassword(password); return 0; }
