Have you ever wondered why when you no longer remember the password of a website, you are never allowed to recover it, but only to reset it? The answer is simple: the administrators don’t even know it! Whenever you access a web application, for example, your Facebook, Google, Yahoo, and Twitter account and so on, you get authentication only if the password you entered matches the one stored in the system. The passage just described takes place in a few tenths of a second and the passwords compared, due to a security issue, are never in the clear, as they undergo a process known as hashing that varies according to the cryptographic algorithm used. From Ciphra this is the best option now.
In small words, this type of encoding takes as input a variable length strings your password and returns the output, also known as MD5 Checksum. It is not possible to trace what originated from a hash thus obtained.
Differences between hashing and cryptography
Hashing and encryption are different ways of protecting information. Encryption allows you to restore the original text later by decoding. Hashing sums up the text in a short print that cannot be decrypted. With the hash print alone, there is no way of knowing exactly which text was summarized even if a given the word always generates the same footprint. In doing so, if an attacker were able to obtain the database of a website containing all the “hash” passwords of the registered users, a …
