If you are new in the MD5 world, you probably ask yourself how to decrypt MD5 passwords in PHP after encrypting them.
In this post, I’ll show you how to do this, but you probably need an explanation about the MD5 algorithm before \ud83d\ude42<\/p>\n\n\n\n
The MD5 cryptographic algorithm is not reversible<\/strong>. I’ll remind you what is the MD5 algorithm and why you can’t reverse it to find the password. By the way, if you are interested in how MD5 decryption really works, I highly encourage you to take a look at my e-book “The Secrets of MD5 Decryption”<\/a> <\/a>here<\/a>. It explains everything you need to know, going directly to the point with practical examples you can test on your computer. You don’t need any hardware to get started, just a few tips I give in this book. <\/p>\n\n\n\n
PHP can encrypt any word into MD5, but not decrypt an MD5 hash to retrieve the original word<\/strong>.
When using the MD5 algorithm to check passwords in PHP, we must have both side encrypted (the password typed and the password stored in the database).<\/strong><\/p>\n\n\n\n
Then I’ll show you how to validate the password in your code (with PHP samples).
And finally, I’ll show you how to use the MD5Online API to find lost passwords.<\/p>\n\n\n\n
