Foreword In most cases, data can be submitted not only by get and post, but also by cookie. The other party may intercept the two methods and determine whether the parameter can be transmitted through cookie
Method: The Firefox browser uses the url under the cookie stored in the browser console to override the parameters
Recommended tool: MODHeader
Use a + sign instead of a space when concatenating parameters
The MD5 message digest algorithm, a widely used password hash function that produces a hash value, is used to ensure that information is transmitted uniformly. The combination of letters and digits (16/32) MD5 treats the entire file as a large text message and uses its irreversible string transformation algorithm to produce a unique digest of the MD5 message
MD5 is a message digest, not a strict encryption algorithm. It’s just to compress data according to specified algorithm growth degree of fixed information is used to restore data for a simple example, the algorithm is to every page of a book the first word on the number of strokes calculated, and stitching together a string, whenever in the same algorithm is a summary of the book, is exactly the same, but through the string, Unable to restore the data, that is, the process is irreversible. The MD5 algorithm is similar to this idea of computer summarization
Now the so-called crack, just hit the library attack
