MD5 is irreversible and cannot be decrypted after encryption!
Many websites can decrypt but should not be said to be decrypted. It should be called credential stuffing.
The website database should have calculated or stored a large number of encrypted MD5 values ??of text.
When the user enters the MD5 value, the website will go to the database to find the source text corresponding to the MD5 value.
This principle~
But MD5 is irreversible after all. It cannot decrypt some large data texts, so the website will prompt that the decryption failed.
