How can I get MD5 password in PHP?
php to:
- $check_pass = mysql_query(“SELECT * FROM users WHERE password = ‘”. $password.
- $pass = trim($_POST[‘pass’]); $pass = md5($_POST[‘pass’]); Then the $pass variable will just be md5’d without having the trim effects on it, to achieve this you should do:
- $pass = trim($_POST[‘pass’]); $pass = md5($pass);
Why should you not use MD5?
Unfortunately, MD5 has been cryptographically broken and considered insecure. For this reason, it should not be used for anything. It is always recommended to store user passwords using a hashing algorithm and you should find that it is equally easy to use SHA-2 in place of MD5 in any modern programming framework.
What is password PHP?
password_hash() creates a new password hash using a strong one-way hashing algorithm. password_hash() is compatible with crypt(). Therefore, password hashes created by crypt() can be used with password_hash(). Note that this constant is designed to change over time as new and stronger algorithms are added to PHP.
Can a password be stored in a MD5 hash?
As you can see this method of hashing will not be secure enough for storing passwords in a database. We need something more secure. To make the md5 hash more secure we need to add what is called “salt”. Salt in this sense of the meaning is random data appended to the password to make the hash more complicated and difficult to reverse engineer.
What is the purpose of MD5 in PHP?
In addition to providing salt (or seed), the md5 is a complex hashing algorithm which uses mathematical rules to produce a result that is specifically not reversable because of the mathematical changes and dataloss in throughput. md5 (or better put: hash algorithms in general) are used to safely store passwords in database.
Is there a way to hash a password in PHP?
PHP provides a native password hashing API that safely handles both hashing and verifying passwords in a secure manner. Another option is the crypt () function, which supports several hashing algorithms.
What can I do to make MD5 more secure?
Make sure to choose a long salt to improve security enough. Another solution is to force users to use a longer password (maybe 15 characters or more). You can also add passwords complexity to make sure they are using uppercase, lowercase and special characters. But be careful, people will often use weak passwords, even if you implement all of this.
