Hashes are generated by one-way mathematical algorithms, which means they cannot be reversed. The only way to break is to brute force them. In this recipe, you will learn how to identify some of the different types of hashes.
Following are the types of hashes.
This is the most common type of hash. MD stands for Message Digest algorithm. These hashes can be identified using the following observation:
- They are hexadecimal
- They are 32 characters in length and of 128 bits, for example,
21232f297a57a5a743894a0e4a801fc3
We may come across such hashes while extracting data from SQL Injection. These hashes can be identified using the following observation:
- They are hexadecimal as well
- They are 16 characters in length of and 64 bits, for example,
