How to generate the random string or random password using Apex?

@Himanshu

You can use following Apex code to generate random string or random password -

Integer len = 10;
Blob blobKey = crypto.generateAesKey(128);
String key = EncodingUtil.convertToHex(blobKey);
String pwd = key.substring(0,len);

you can follow the following link-

Hi,

Hope this will help you.

public static String generateRandomString(Integer len) {
final String chars = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789abcdefghijklmnopqrstuvwxyz';
String randStr = '';
while (randStr.length() < len) {
Integer idx = Math.mod(Math.abs(Crypto.getRandomInteger()), chars.length());
randStr += chars.substring(idx, idx+1);
}
return randStr;
}
Thanks.

Hi,

Adding some code snippet

Here is a static method that accepts a desired string length as an argument. It takes a full string of ASCII numbers and letters and loops through the index of your desired string length, randomly choosing an index in the full character string.

public static String generateRandomString(Integer len) {
final String chars = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789abcdefghijklmnopqrstuvwxyz';
String randStr = '';
while (randStr.length() < len) {
Integer idx = Math.mod(Math.abs(Crypto.getRandomInteger()), chars.length());
randStr += chars.substring(idx, idx+1);
}
return randStr;
}

Thanks
