如何比较laravel中的两个加密（bcrypt）密码

Question

How to compare two bcrypt password

$pass1 = '$2y$10$ooPG9s1lcwUGYv1nqeyNcO0ccYJf8hlhm5dJXy7xoamvgiczXHB7S';

And

$pass2 = '$2y$10$QRgaiS6bpATKKQeT22zGKuHq.edDfXQc2.4B3v.zaN.GtGwoyQuMy';

Both $pass1 & $pass2 are bcrypt for 'test'.

How I can check for equality. without using text 'test' like this

$hash1 = Hash::make('test');
$hash2 = Hash::make('test');

var_dump(Hash::check('test', $hash1) && Hash::check('test', $hash2));

Answer 1

if(Hash::check('plain-text-password',$cryptedpassword)) {
    // Right password
} else {
    // Wrong one
}

Answer 2

You can simply use Hash::check() method eg:

if(Hash::check('plain-text', $hashedPassword)) {
    return true;
}

Answer 3

您实际上无法将两个加密的 bcrypt 密码直接作为字符串相互比较，因为加密包含使哈希值每次都不同的盐。

Answer 4

You can try this way:

if (Hash::check('test', bcrypt('test'))) {
    return 'match!!';
}else{
    return 'not match!!';
}

Answer 5

you can compare hash encrypt the password using Hash .

but note that in this method the first value should be plain-text and second bcrypt value.

Hash::check('test', bcrypt('test'))
