Md5 Hash Generator



About Md5 Hash Generator

These days, with the storage of all data in the cloud, it is important to keep your data’s security at the utmost priority. The most secure algorithm should be employed to encrypt and safeguard private data.

One of the best ways to encrypt and safeguard private data is by hashing. MD5 hashing is widely used to store a one-way hash of a password, often with key stretching and also used in the field of electronic discovery, to provide a unique identifier for each document that is exchanged during the legal discovery process.

For example, you can turn this simple sentence "This is amazingly good", into a 128-bit hash like "c50fa115888a9d65fdc0d199cd68593c" when you pass it through the MD5 hashing algorithm. This is encrypted into 128 bits long, which works out to 32 characters.

Despite the security vulnerabilities encountered in the future, MD5 remains a crucial part of data infrastructure in a multitude of environments.


How is MD5 useful?

Hashing generally consists of encoding a general string of information into an intricate piece of data. This is done to scramble the data so that it completely transforms the original value, making the hashed value utterly different from the original. MD5 (Message Digest Method 5) is a cryptographic hash algorithm used for converting a string of any length into a 128-bit digests. It represents the digests as 32 digit hexadecimal characters.

Some of the best uses of this is in:

Password Verification:

One way most websites store credentials of users is in a hashed format to prevent third parties from reading the passwords. Since hash functions always create the same output for the same input, comparing password hashes is much more private. Unix systems use the MD5 Algorithm to store the passwords of the user in a 128-bit encrypted format.

This is how this works.

  • User signs up on the website with a new username and password
  • The password is passed through a hash function and the digest is stored on the server as encrypted data
  • Everytime a user logs in, they have to enter the password again
  • The password again passes through the hash function to generate a digest
  • If the newly generated digest matches the first one on the server, login is verified and the user is able to login.

This simple process works great when MD5 hash is uterlized on a server.

Integrity Verification:

Another way this work is is integrity verification of files. Some files can be checked for data corruption using hash functions. Just like in password verification, Md5 hash functions will always give the same output for similar input, irrespective of any parameters.

This is how that works in this case.

  • An online user uploads a file on a server via the internet
  • Hash digest is uploaded along the file when this is done
  • When an online user downloads this file, the hash diest is recalculated
  • If the newly generated digest matches the first hash value, the file integrity is confirmed.

This is how generally hashing works and MD5 algorithm is one of the best ways to do this. MD5 is still widely used, most notably by security research and antivirus companies. Some of the content management systems (CMS) also use MD5 for password hashing.

There are other ways of encryption such as the SHA1 and HAVAL.


Advantages of MD5 Hash

An MD5 hash is not an encryption process. MD5 hash is simply a fingerprint of the given input or entered information. MD5 hash is a one-direction algorithm, which means it's irreversible. It is a one-way process and as such it is almost impossible to reverse engineer an MD5 hash to retrieve the original string. Some of the advantages and uses of Md5 hash include:

  • It is very easy to compare and Generate: A 32 digit digest is easier to compare when verifying the digests which is not the case with some of the newer methods.
  • MD5 hash is almost 3 times faster to produce than the SHA1 for the same information
  • Uses Low Resource: A low memory footprint is necessary to integrate multiple services into the same framework without a CPU overhead.
  • Extremely low collision ratio: Collisions are theoretically impossible.
