Now if MD5 is a one way function, how do we decrypt it? We actually don't \"decrypt\" MD5, we use this word because it's easy to understand, but hashing function cannot be decrypted. It can be reversed. For this to happen, the only way is to compare a given hash with a database of couples password:hash. This is what we have on this website. We have billions hashes stored in our database, and more in our premium database. When you enter a hash in our search bar, we look into our database if we have a match. If so we provide you with the password.
However, this method is not very efficient, as it requires a lot of storage space and computing power to generate and store all the possible hashes and their inputs. A better way to reverse MD5 hashes is to use a technique called rainbow tables. A rainbow table is a precomputed table of hashes and inputs that allows to find the input for a given hash in a much faster and smaller way than brute force or simple lookup tables.
There are many websites that offer online MD5 decrypter services, such as md5online.org or md5decrypt.net. These websites claim to have huge databases of hashes and inputs, as well as rainbow tables, that can help you crack any MD5 hash in seconds. However, these websites are not very reliable, as they may not have the hash you are looking for, or they may charge you money for premium access.
How Facebook Hashes Passwords?
According to a presentation by Facebook engineers in 2014, Facebook uses a combination of MD5, HMAC, scrypt and cryptoservice to hash and store passwords. The process is as follows:
The user enters their password on the login page.
The password is hashed with MD5 on the client side (browser) and sent to the server.
The server receives the MD5 hash and applies an HMAC function with a secret key that is stored on a separate server.
The result of the HMAC function is then hashed with scrypt, a memory-hard function that requires a lot of RAM and CPU to compute.
The result of scrypt is then encrypted with cryptoservice, a service that uses hardware security modules (HSMs) to encrypt and decrypt data without exposing the encryption keys.
The encrypted result is then stored in the database as the password hash.
This process makes it very hard for anyone to crack Facebook passwords, even if they manage to steal the database of hashes. They would need to know the secret key for HMAC, which is stored on a separate server, and they would need access to the cryptoservice and its HSMs, which are physically secured. They would also need a lot of time and resources to run scrypt on each hash.
Facebook also uses other security measures to protect passwords, such as salting (adding random data to each password before hashing), peppering (adding another secret key to each password before hashing), rotating keys (changing the secret keys periodically), hashing previous passwords (to prevent users from reusing old passwords), and monitoring login attempts (to detect and block brute force attacks).
What are the Advantages and Disadvantages of MD5 Hash?
MD5 hash has some advantages and disadvantages as a password hashing algorithm. Some of the advantages are:
It is fast and easy to compute, which makes it suitable for large-scale applications.
It produces a fixed-length output of 128 bits, which is convenient for storage and comparison.
It has a low probability of producing collisions, which means that two different inputs are unlikely to have the same hash output.
Some of the disadvantages are:
It is insecure and vulnerable to attacks, such as brute force, dictionary, rainbow tables, and collision attacks. These attacks can exploit the weaknesses of MD5 and find the original input from the hash output.
It is outdated and deprecated, as newer and stronger hashing algorithms have been developed, such as SHA-256, SHA-3, or Argon2.
It is not suitable for password hashing by itself, as it does not provide any protection against guessing or cracking. It needs to be combined with other techniques, such as salting, peppering, stretching, or encryption.
Therefore, MD5 hash is not recommended for password hashing in modern applications. It should be replaced by more secure and robust algorithms that can resist various attacks and provide better security for passwords.
What are the Ethical Issues of Hacking Facebook Passwords?
Hacking Facebook passwords is a serious ethical issue that can have negative consequences for both the hackers and the victims. Hacking Facebook passwords can violate the privacy and security of the users, as well as the terms and conditions of the platform. Hacking Facebook passwords can also expose the users to various risks, such as identity theft, fraud, blackmail, harassment, or cyberbullying.
Hacking Facebook passwords is not only unethical, but also illegal in many countries. Depending on the laws and regulations of each jurisdiction, hacking Facebook passwords can be considered as a criminal offense that can result in fines, imprisonment, or both. Hacking Facebook passwords can also lead to civil lawsuits from the victims or from Facebook itself, who can claim damages for the breach of contract or the violation of their rights.
Therefore, hacking Facebook passwords is not a harmless or trivial activity. It is a serious and irresponsible act that can harm both the hackers and the victims. It is also a violation of the moral and legal principles that govern the use of the internet and social media. Hacking Facebook passwords should be avoided and discouraged by anyone who values their integrity and reputation.
What are the Alternatives to MD5 Hash?
MD5 hash is not the only hashing algorithm available. There are many other algorithms that have been developed and improved over the years, some of which are more secure and robust than MD5. Some of the alternatives to MD5 hash are:
SHA-2: SHA stands for Secure Hash Algorithm. The second version of the algorithm, SHA-2, consists of six variants: SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224, and SHA-512/256. The numbers indicate the bit length of the hash output. SHA-2 is widely used in cryptography and security applications, such as digital signatures, SSL certificates, and password hashing.
SHA-3: SHA-3 is the latest version of the Secure Hash Algorithm, which was selected in 2012 after a public competition. SHA-3 is based on a different design than SHA-2, called sponge construction. SHA-3 also has six variants: SHA3-224, SHA3-256, SHA3-384, SHA3-512, SHAKE128, and SHAKE256. The last two are extendable-output functions that can produce arbitrary-length hash outputs.
Argon2: Argon2 is a memory-hard hashing algorithm that was designed for password hashing and key derivation. It won the Password Hashing Competition in 2015 and became a standard in 2017. Argon2 has three variants: Argon2d, Argon2i, and Argon2id. The first one is optimized for resistance against GPU attacks, the second one is optimized for resistance against side-channel attacks, and the third one is a hybrid of both.
scrypt: scrypt is another memory-hard hashing algorithm that was designed for password hashing and key derivation. It was created in 2009 and became a standard in 2016. scrypt requires a lot of RAM and CPU to compute, which makes it hard to parallelize or optimize with hardware. scrypt is used by some cryptocurrencies, such as Litecoin and Dogecoin.
bcrypt: bcrypt is a password hashing algorithm that was based on the Blowfish cipher. It was created in 1999 and became a standard in 2008. bcrypt uses a salt (a random value) and a cost factor (a number that determines the complexity of the computation) to generate hash outputs. bcrypt is resistant to brute force and rainbow table attacks.
These are some of the most common and popular alternatives to MD5 hash. However, there are many other hashing algorithms that exist or are being developed. The choice of a hashing algorithm depends on the purpose and the requirements of each application.

How to Protect Your Facebook Password?
Your Facebook password is the key to your account and your personal information. If someone gets access to your password, they can log in to your account and do things like post on your timeline, send messages to your friends, or access your photos and videos. Therefore, it is very important to protect your Facebook password and prevent it from being stolen or hacked.
Here are some tips on how to protect your Facebook password and keep your account secure:
Change your password regularly. You should change your password at least every six months, or whenever you suspect that someone else might know it. To change your password, go to Settings > Security and Login > Change Password. Choose a strong and unique password that follows the guidelines mentioned above.
Use two-factor authentication. Two-factor authentication adds an extra layer of security to your account by requiring you to enter a code or confirm your login on another device when you log in from a new browser or device. This way, even if someone knows your password, they won't be able to access your account without the code or confirmation. To turn on two-factor authentication, go to Settings > Security and Login > Two-Factor Authentication. You can choose to receive codes via text message, a third-party authentication app, or a security key.
Don't share your password with anyone. You should never tell anyone your password, not even your friends, family, or Facebook employees. Facebook will never ask you for your password in an email, message, or phone call. If someone asks you for your password, don't give it to them and report them to Facebook.
Don't use the same password for other accounts. You should have a different password for each of your online accounts, especially those that contain sensitive information, such as your email, bank, or social media accounts. This way, if one of your accounts is compromised, the others remain safe. You can use a password manager to help you create and store different passwords for each account.
Log out of Facebook when you use a shared device. If you use a public or shared computer or device, such as at a library, school, or cafe, make sure to log out of Facebook when you're done. This will prevent other people from accessing your account or changing your password. To log out of Facebook, click the arrow icon in the top right corner and select Log Out.
These are some of the best practices that can help you protect your Facebook password and keep your account secure. Remember that a secure password is one of the most effective ways to prevent hackers and cybercriminals from stealing your personal information and data.
