Adam Harvey https://linux.conf.au/schedule/30208/view_talk When you say “hash function” in a room full of developers, people tend to think of the classics: MD5, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, SHA-OHGODPLEASESTOP, and the like — cryptographic hash functions intended for cryptographic uses. There’s another world out there, though: non-cryptographic hashes. Sometimes you just need to figure out if you’ve already seen a string or structure. Sometimes you need a basic checksum. Sometimes you need a hash that’s just fast and can fit into a 32 bit integer. I’ll run through the state of the art in the world of non-cryptographic hashing — what your best options are, how they compare in terms of CPU and memory usage, and how they work. Who takes it? Whose mixing function reigns supreme? Let’s find out. * I’m saying “five”, but realistically I’m going to cover as many modern options as I can fit into the time available. Let’s say “five plus or minus two” in reality.

Python Hash-Decrypter Program | Decode Hash Encryption 🔐
 
15:05
Hello Friends, In This Video, I'm Gonna Show You How You Can Encrypt & Decrypt The Hash String With The Help Of Hashlib Python Module Python-Hash-Cracker Program - https://goo.gl/zs3ikD HASHING : - If you need secure hashes or message digest algorithms, then Python’s standard library has you covered in the hashlib module. It includes the FIPS secure hash algorithms SHA1, SHA224, SHA256, SHA384, and SHA512 as well as RSA’s MD5 algorithm. Python also supports the adler32 and crc32 hash functions, but those are in the zlib module. One of the most popular uses of hashes is storing the hash of a password instead of the password itself. Of course, the hash has to be a good one or it can be decrypted. Another popular use case for hashes is to hash a file and then send the file and its hash separately. Then the person receiving the file can run a hash on the file to see if it matches the hash that was sent. If it does, then that means no one has changed the file in transit Cryptographic hashes are used in day-day life like in digital signatures, message authentication codes, manipulation detection, fingerprints, checksums (message integrity check), hash tables, password storage and much more. They are also used in sending messages over a network for security or storing messages in databases. There are many hash functions defined in the “hashlib” library in python. Some of the most used hash functions are: MD5: Message digest algorithm producing a 128 bit hash value. This is widely used to check data integrity. It is not suitable for use in other fields due to the security vulnerabilities of MD5. SHA: Group of algorithms designed by the U.S's NSA that are part of the U.S Federal Information processing standard. These algorithms are used widely in several cryptographic applications. The message length ranges from 160 bits to 512 bits. Functions associated : encode() : Converts the string into bytes to be acceptable by hash function. digest() : Returns the encoded data in byte format. hexdigest() : Returns the encoded data in hexadecimal format. ----------------------------------------------------------------------------------------------------------- Hope This Video Is Helpful For You ► Connect with me! ◄ Facebook - http://bit.ly/2tbOg3b Google+ - http://bit.ly/2jrWz6g Instagram - http://bit.ly/2tbR14z Reddit - https://bit.ly/2J5Vqfm ★★★Watch my most recent videos playlist★★★ Kali Linux - https://goo.gl/36M3JD Deep Web - https://goo.gl/7ueKNh Python Coding - https://goo.gl/dCtyrS Java Coding - https://goo.gl/oxFo8W Basic Computer - https://goo.gl/kwFXM3 Hacking - https://goo.gl/vjT916 Games Benchmark - https://goo.gl/eshw3T Gaming - https://goo.gl/mLuQwf Notepad Tricks -https://goo.gl/3uapMJ CMD Tricks - https://goo.gl/x1KH8C Facebook Tricks - https://goo.gl/1JV9Fz Problem Solved - https://goo.gl/eJwjXq Gmail Tricks - https://goo.gl/fSpbaB And talking about subscribing, please subscribe to my channel, if you enjoyed this video and want more how-to, Thanks so much for watching!

Using MD5/SHA256 Hashes to Verify File Integrity
 
07:45
Windows PowerShell command: Get-FileHash [-Algorithm MD5] .\filename Remove the bracket if you want to use MD5 instead of the default SHA256. Make sure you are either navigated to your desired file’s directory using the “cd” command or you input the full path to the file. A full path looks like “C:\Program Files\Mozilla\firefox.exe” and a ‘current directory’ file has to have the “.\” appended to the filename. In the years that I have spent downloading files from the internet, I have learned that it is important to check the integrity of major files. The common user does not know and understand hashing, but this isn't your Grandma's house.

What is Brute Force Attack? How it's done? | [Hindi]
 
03:25
Video Title: What is Brute Force Attack? How it's done? | [Hindi] In this video i will tell you what is brute force attack and how it's done. We will see in detail how it works. we will also discuss what is dictionary attack and how its different from brute force attack. Everything explained in Hindi. Extra info: In cryptography, a brute-force attack consists of an attacker trying many passwords or passphrases with the hope of eventually guessing correctly. The attacker systematically checks all possible passwords and passphrases until the correct one is found. Alternatively, the attacker can attempt to guess the key which is typically created from the password using a key derivation function. This is known as an exhaustive key search. A brute-force attack is a cryptanalytic attack that can, in theory, be used to attempt to decrypt any encrypted data (except for data encrypted in an information-theoretically secure manner). Such an attack might be used when it is not possible to take advantage of other weaknesses in an encryption system (if any exist) that would make the task easier. When password guessing, this method is very fast when used to check all short passwords, but for longer passwords other methods such as the dictionary attack are used because a brute-force search takes too long. Longer passwords, passphrases and keys have more possible values, making them exponentially more difficult to crack than shorter ones. Brute-force attacks can be made less effective by obfuscating the data to be encoded making it more difficult for an attacker to recognize when the code has been cracked or by making the attacker do more work to test each guess. One of the measures of the strength of an encryption system is how long it would theoretically take an attacker to mount a successful brute-force attack against it. Brute-force attacks are an application of brute-force search, the general problem-solving technique of enumerating all candidates and checking each one. ----------------------------------------- Like our Facebook page: https://www.facebook.com/DesiScientistReal/ Follow us on Twitter: https://twitter.com/DS_Asli

Disk Imaging / Acquisition Using Linux DD / DCFLDD command
 
06:22
Disk Acquisition in Linux using old school DD command and DCFLDD for an expanded usage of DD. Command Usage : {dd if=/dev/sda of=/disk1.img} Where if=Source FILE / DIsk / Partition /Block of=Destination Image Output Formats supported : IMG , DD DCFLDD : Enhanced version of dd Supports the following : 1. On-the-fly hashing of the transmitted data. 2. Progress bar of how much data has already been sent. 3. Wiping of disks with known patterns. 4. Verification that the image is identical to the original drive, bit-for-bit. 5. Simultaneous output to more than one file/disk is possible. 6. The output can be split into multiple files. 7. Logs and data can be piped into external applications. Command Usage : {dcfldd if=/dev/sourcedrive hash=md5,sha256 hashwindow=10G md5log=md5.txt sha256log=sha256.txt \ hashconv=after bs=512 conv=noerror,sync split=10G splitformat=aa of=destinationdriveimage.dd} Where * hash=NAME Available parameters : md5, sha1, sha256, sha384 or sha512 Note- By default algorithm is set to md5. To select multiple algorithms , seperate the hash names using comma. * bs=BYTES Defines Number of Bytes , used after setting a parameter to define the number of bytes on that operation * hashwindow=BYTES Helps you to perform hash on every 'X BYTES' amount of data * hashconv=[before|after] Helps you to perform the hashing before or after the BS *conv=KEYWORDS convert the file as per the comma separated keyword list e.g. noerror/sync - Video Courtesey - Infinite Skills Note: {If you have any issue with the content , do contact back or drop a comment and will do the needful as soon as possible.}
