Therefore, it is recommended to store the result in a database column that can expandīeyond 60 characters (255 characters would be a good choice). For that reason, the length of the result from using this identifier can change over Note that this constant is designed to change over time as new and stronger algorithms are added PASSWORD_DEFAULT - Use the bcrypt algorithm (default as of PHP 5.5.0).The following algorithms are currently supported: Password_hash() creates a new password hash using a strong one-way hashing Password_hash( string $password, string| int| null $algo, array $options = ): string But if you are just learning database and just simply creating one database for learning purpose you can use md5 encryption.Getting Started Introduction A simple tutorial Language Reference Basic syntax Types Variables Constants Expressions Operators Control Structures Functions Classes and Objects Namespaces Enumerations Errors Exceptions Fibers Generators Attributes References Explained Predefined Variables Predefined Exceptions Predefined Interfaces and Classes Predefined Attributes Context options and parameters Supported Protocols and Wrappers Security Introduction General considerations Installed as CGI binary Installed as an Apache module Session Security Filesystem Security Database Security Error Reporting User Submitted Data Hiding PHP Keeping Current Features HTTP authentication with PHP Cookies Sessions Dealing with XForms Handling file uploads Using remote files Connection handling Persistent Database Connections Command line usage Garbage Collection DTrace Dynamic Tracing Function Reference Affecting PHP's Behaviour Audio Formats Manipulation Authentication Services Command Line Specific Extensions Compression and Archive Extensions Cryptography Extensions Database Extensions Date and Time Related Extensions File System Related Extensions Human Language and Character Encoding Support Image Processing and Generation Mail Related Extensions Mathematical Extensions Non-Text MIME Output Process Control Extensions Other Basic Extensions Other Services Search Engine Extensions Server Specific Extensions Session Extensions Text Processing Variable and Type Related Extensions Web Services Windows Only Extensions XML Manipulation GUI Extensions Keyboard Shortcuts ?

You will get your password in simple text. If you now want to check what is your password simply copy the code of password column and google for md5 decrypter or go to this link: and paste the code and tap on the decrypt button. You will get the output printed like 1 row affected in 0.0023 secĪnd your password of user_id = 1 will be encrypted as25d55ad283aa400af464c76d713c07ad UPDATE userdetails SET pass = MD5('12345678') WHERE 'user_id' = 1 If i have a table called "userdetails" columns for id = "user_id", for email = "email_id", & for password = "pass" and my password is "12345678" Here password in MD5 function is the one which you want to encrypt in your database UPDATE table_name SET column_name = MD5('password') WHERE 'column_name' = column_value For Encrypting password your database with md5() use this query in SQL.
