Different Types of Hashes and Strings

What Is a Hash?

Ok, firstly alot of you still believe that hashes can be "decrypted", this is a common misconception because hashes are generated by One Way Cryptographic Hash Algorithms these means the algorithm that created them CAN NOT be reversed to determine the plain text password.




These one way functions are used by computers to prevent storing passwords in plain text in memory, instead when a password is entered (for example at a log in screen) a one way hash algorithm is applied to the supplied password and then the hashed output is compared to the hash for that user, stored in memory. If the two hashes match, the passwords are the same and the user is authenticated, if the two hashes are not the same the passwords do not match and the user is denied access.

[+]Different Types of Hashes and How to Identify Them[+]

MD5 - The most common hash you will come across in the wild is an MD5 hash (Message-Digest algorithm)

These hashes are easily identified by the following factors:

• They are always 32 characters in length (128 Bits)
• They are always hexadecimal (Only use characters 0-9 and A-F)

Code:

Example -e906c5714b69671d95722103e4753554

 The Encrypted Code:Mryosojmlf

If the hash breaks one of these rules - IT IS NOT MD5.

SHA1 - Still used frequently on the internet and is one of a large family of Secure Hash Algorithms.
These hashes are easily identified by the following factors:

• They are always 40 Characters in length (160 bits)
• They are always hexadecimal (Only use characters 0-9 and A-F)

Code:

Example - 9bbe96004afaf67cfc348a8792e6a69d926cab4d:Mryosojmlf

If the hash breaks one of these rules - IT IS NOT SHA1.

Hex-In mathematics and computing,hexadecimal (also base 16, or hex) is apositional numeral system with a radix, or base, of 16. It uses sixteen distinct symbols, most often the symbols 0–9 to represent values zero to nine, andA, B, C, D, E, F (or alternatively a, b, c, d, e,f) to represent values ten to fifteen.

BINARY-

A Binary Number is made up of only 0s and 1s.
