強密碼建議程式
每年5月7日,全球各組織都會提醒使用者強密碼的重要性。根據科技巨頭谷歌的資料;
24% 的終端使用者使用“password”或“Qwerty”作為其帳戶密碼。
而他們所有使用者中只有 34% 定期更改其帳戶密碼。
在當今這個科技發展迅速的世界裡,每次登入嘗試都可能遭到網路犯罪分子的攻擊。但如今仍有許多人繼續使用弱密碼來保護其工作和個人帳戶。
在這裡,我們將討論並檢查建立的密碼是極弱、弱、中等、強還是極強。為此,我們將根據演算法檢查密碼建立標準。在今天的文章中,我們將學習如何使用 C++ 程式碼建立強密碼建議程式。
如何建立強密碼 - 演算法
這是一個強密碼的一般演算法。它可以幫助開發人員在 C++ 環境中開發密碼建議系統並找到其密碼的特定標準。
步驟 1 − 開始
步驟 2 − 理想密碼的長度至少應為八個字元。
步驟 3 − 必須包含至少一個數字字元。
步驟 4 − 必須包含至少一個小寫字元。[例如:a、b、c.....、z]
步驟 5 − 必須包含至少一個大寫字元。[例如:A、B、C......、Z]
步驟 6 − 必須包含至少一個特殊字元。[例如:!@#$%^&*()-+]
步驟 7 − 結束
建立強密碼建議程式 - 語法
switch (k) {
case 1:
if ((count_alphabet == 7) && (count_number == 0 || count_ALPHABET == 0 || count_ALPHABET == 7 || count_s_symbol == 0))
break;
key = getKey();
password = password + alphabet[key];
count_alphabet++;
count++;
break;
case 2:
if ((count_ALPHABET == 7) && (count_number == 0 || count_alphabet == 0 || count_alphabet == 5 || count_s_symbol == 0))
break;
key = getKey();
password = password + ALPHABET[key];
count_ALPHABET++;
count++;
break;
case 3:
if ((count_number == 7) && (count_alphabet == 0 || count_alphabet == 1 || count_ALPHABET == 3 || count_ALPHABET == 0 || count_s_symbol == 0))
break;
key = getKey();
key = key % 10;
password = password + number[key];
count_number++;
count++;
break;
case 4:
if ((count_s_symbol == 1) && (count_alphabet == 0 || count_alphabet == 1 || count_ALPHABET == 0 || count_ALPHABET == 1 || count_number == 0))
break;
key = getKey();
key = key % 6;
password = password + s_symbol[key];
count_s_symbol++;
count++;
break;
}
cout << "\n-----------------------------\n";
cout << " Enter The Password \n";
cout << "------------------------------\n\n";
cout << " " << password add here;
cout << "\n\n Press any key continue \n";
getchar();
}
在此語法中,條件檢查理想密碼的最低要求。我們將所有可能的條件分成四種情況,分別檢查字母、數字和特殊符號字元是否已根據最低要求滿足。然後檢查剩餘的其他字元,並結束。
方法 – 建立強密碼建議程式
方法 1 − 建立強密碼建議程式環境
方法 2 − 檢查密碼是強、弱還是中等
方法 3 − 根據條件檢查密碼
建立強密碼建議程式環境
在此 C++ 構建程式碼中,系統將檢查輸入資料(密碼)的強度。它將掃描輸入以查詢所有提到的理想密碼標準。如果所有標準都匹配,則它是一個理想密碼。否則,如果輸入中缺少任何字元,它將返回一些隨機生成的密碼。
示例 1
#include <bits/stdc++.h>
using namespace std;
string add_more_char(string str, int need){
int pos = 0;
string low_case = "abcdefghijklmno";
for (int a = 0; a < need; a++) {
pos = rand() % str.length();
str.insert(pos, 1, low_case[rand() % 26]);
}
return str;
}
string suggester(int m, int o, int a, int d, string str) {
string num = "0123456789";
string low_case = "abcdefghijklmno";
string up_case = "ABCDEFGHIJKLMNO";
string spl_char = "@#$_()!*&%#+-=.`";
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;
}
輸出
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
檢查密碼是強、弱還是中等
根據提到的演算法和 C++ 構建程式碼;編碼的字串檢查輸入強度。當所有條件都滿足時,整個方法返回“強”作為輸出。如果僅滿足前三個步驟且密碼長度至少為八個字元,則將返回“中等”。
示例 2
#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;
}
輸出
Strength of password:-Strong
根據條件檢查密碼
在此程式碼中,我們將對特定密碼執行驗證操作。以下是具體步驟:
從使用者那裡獲取輸入。
現在將檢查使用者輸入的密碼組合。
密碼被分類為強、中等和弱。
如果所有條件都為真,則它將是一個強密碼。
否則,為中等或弱。
示例 3
#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;
}
輸出
