SHA1 is a hash algorithm that is created by the National Security Agency (NSA). SHA1 hash algorithm is generally used in security and data integrity applications. SHA-1 is created in 1995 as the successor of the SHA-0. Both SHA1 and SHA-1 refer to each other. Secure Hash Algorithm 1 or SHA1 SHA1 is in a … Read more
apt command is used to install, update, remove packages in Linux distributions like Ubuntu, Debian, Mint, Kali. apt is mainly used with the deb packages. With the apt update or apt-get update command the repository information is downloaded to from the deb repositories to the local repositories. Hash is used to checking if the downloaded … Read more
Hash algorithms are the heart of the cryptography and security. SHA-256 is a Secure Hash Algorithm which will generate an output hash value in 256 bit. SHA-256 is designed by the National Security Agency (NSA). SHA-256 is one of the cryptographic hash functions. SHA-256 has also named a one-way function where the generated hash value … Read more
MD5 is a checksum or hash calculation method for files. MD5 checksum consists of 128-bit value which is generally expressed as the hexadecimal format with which consist of 32 characters. MD5 Attributes MD5 is a cryptography algorithm which provides some attributes which make it useful for different cases like security, operation etc. Here is the list … Read more
checksum is a function used to calculate some value for given data. As we see check is used to check given data with the calculated sum. Data may be little or very big like 1 MB, 10 MB, etc. but the checksum value will be the same size but different for each different type of data. the … Read more
Hash-based Authentication Message Code or HMAC is used to authenticate message with hash functions. Message authentication is important mechanism in cyber security and used to check message authenticity. There are different ways and mechanisms for Message Authentication. Message Message is the data, text, image or whatever else we want to authenticate. Message is checked against … Read more
Security is important part of the today IT and gains more respect from IT world. Hashing is a security measure to protect and check our data. In this tutorial we will look how to use hash with tables and strings. What is Hash Hash is a function where provided data will be converted into another … Read more
This is the most powerful cracking mode. Keep in mind that generally cracking will never end in this mode if there is no password because combinations are too large. Configurations about Incremental Mode can be found in configuration file [Incremental:MODE] section. $ john –incremental unshadowed –incremental is used to specify incremental Mode Set Only Numeric Chars for … Read more
As we stated before in single crack mode [List.Rules:Single] method of configuration file is used. In this mode login:password are cracked by using default password-list. Single Mode is much faster than Wordlist Mode. Linux Example We will crack linux passwords with Single Mode. First we need the create one file by unshadowing /etc/passwd and /etc/shadow like below $ unshadow /etc/passwd … Read more
Hackers preferred mode for tool usage is cli. John is developed for cli primarily. But there is also a gui part and can be installed like below. We named is johnny $ apt-get install johnny -y We can provide login and password hashes like below We can select password hash type manually but … Read more
