Introduction to Password Cracking


The term password cracking (“pass cracking”) typically refers to the bruteforce recovery of one or more plaintext passwords from hashed passwords known as hashes. Password cracking means that a hacker or cracker could obtain accessibility to a hashed or encrypted password, either by decoding the password encrypted data source or hacking a hashed password emailed over an open network, or using various other methods such as bruteforcing or decrypting to swiftly and without limitation to examine if a cracked password is possible to decode. With the hashed password, the cracker could function undetected, and if the cracker or decrypter has actually acquired many hashed passwords, the chances for cracking at least one is fairly high.

One common method of password recovery is through the utilization of hash cracking tools such as Hashcat and John The Ripper. A combolist/wordlist/dictionary list, bruteforcing methods and hash decoders are often used to crack these password hashes. Such automated programs bruteforce cryptographic methods of encryption by using CPU and GPU tools, techniques and optimization on encrypted hashes (MD5/SHA1/MYSQL/NTLM/DES etc.). This is also known as Hash Cracking.

PassCracking uses combined techniques (classic rainbow tables, hybrid rainbow tables, dictionary, bruteforcing, combination) for MD5 and MYSQL (MYSQL323, MYSQL4 and MYSQL5) hashes and simple dictionary search for other hashes. Many online databases provide SHA1/MD5 Hash Crackers [MD5 Crack/Crack MD5] using these techniques providing cracking pass and decrypted/decoded plaintext hashes and passwords. We believe that this online hash cracking project is most simple to use but most technologically advanced in order to bruteforce and decrypt UNIX and salted hashes. The hashes database is unique and consists of many different length real passwords.

The advanced decryption and bruteforcer techniques used by password crackers also have the ability to crack Windows Hashes (LM, NTLM, DCC), CMS Hashes (Joomla, e107, WordPress, osCommerce), Standard Hashes (MD4, SHA-1, SHA2, SHA-256, SHA-512), Database Hashes (MSSQL, PostgreSQL), UNIX Hashes (DES(Unix), MD5(Unix), MD5(APR)), Forum Hashes (IPB, vBulletin, Xenforo, SMF, phpBB3, MyBB) and Other/Custom Hashes (WPA, WPA2-PSK, RAdmin).

To enhance the personal privacy of passwords, the saved password verification information is generally produced by applying a one-way function to the password, perhaps in mix with other readily available data dumps. Even though functions that produce hashed passwords might be cryptographically secure, metadata and algorithms of a hashed password give a fast way to confirm cracking of a password by using the function to each cracking profile, and reviewing the outcome to the password hash information.

Cracking could be integrated with various other methods. Use of a hash-based challenge-response verification technique for password verification might leak a hashed password to an eavesdropper or spy, who could then crack the password. A variety of stronger cryptographic protocols exist that do not subject hashed-passwords during verification over a network, either by safeguarding them in transmission making use of important protocols and standard (such as HTTP2, HTTPS, SSL/TLS), or by utilizing a zero-knowledge password recovery evidence.
