Generate: MD5 Generator

What does MD5 Generator do?

MD5 Generator is an online tool with an algorithm which allows you to generate a unique MD5 hash by converting strings. The length of an MD5 hash is fixed to 128 bits or 16 bytes.

What is MD5?

MD5 (technically called MD5 Message-Digest Algorithm) is a cryptographic hash function whose main purpose is to verify that a file has been unaltered.

Instead of confirming two sets of data are identical by comparing the raw data, MD5 does this by producing a checksum on both sets and then comparing the checksums to verify they're the same. You can instantly get the MD5 checksum or hash of a string of letters, numbers, and symbols with MD5 Generator.

What is hashing?

Hashing consists of converting 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.

Hashing uses a hash function to convert standard data into an unrecognizable format. These hash functions are a set of mathematical calculations that transform the original information into their hashed values, known as the hash digest or digest in general. The digest size is always the same for a particular hash function like MD5 or SHA1, irrespective of input size.

Hashing has two primary use cases: password verification and integrity verification. It is common to store user credentials of websites in a hashed format to prevent third parties from reading the passwords. Since hash functions always provide the same output for the same input, comparing password hashes is much more private. On the other hand, some files can be checked for data corruption using hash functions. Like the above scenario, hash functions will always give the same output for similar input, irrespective of iteration parameters.

How does MD5 work?

MD5 runs entire files through a mathematical hashing algorithm to generate a signature that can be matched with an original file. That way, a received file can be authenticated as matching the original file that was sent, ensuring that the right files get where they need to go.

MD5 Generator converts data into a string of 32 characters. For example, the word “frog” always generates this hash: 938c2cc0dcc05f2b68c4287040cfcf71. Similarly, a file of 1.2 GB also generates a hash with the same number of characters. When you send that file to someone, their computer authenticates its hash to ensure it matches the one you sent.

If you change just one bit in a file, no matter how large the file is, the hash output will be completely and irreversibly changed. Nothing less than an exact copy will pass the MD5 test.

What is it used for?

MD5 is used for file authentication.

In a web application, it is used for security purposes. e.g., Secure password of users etc.

Using this algorithm, we can store our password in 128 bits format. It can also be used for password verification.

It is used to digest the message of any size.

It is also possible to benefit from MD5 Generator for game boards and graphics.

What are the advantages?

MD5 is easy to compare. Unlike the latest hash algorithm families, a 32-digit digest is relatively easier to compare when verifying the digests.

It is useful for storing passwords. Passwords need not be stored in plaintext format, making them accessible for hackers and malicious actors. When using digests, the database also gets a boost since the size of all hash values will be the same.

It requires low resource. A relatively low memory footprint is necessary to integrate multiple services into the same framework without a CPU overhead.

It is possible to perform an integrity check: You can monitor file corruption by comparing hash values before and after transit. Once the hashes match, file integrity checks are valid, and it avoids data corruption.

What are the disadvantages?

Brute force attacks on MD5 hashes are fast. A brute force attack is a way to find a password by trying many possibilities. Either by guessing what the user could have used (birthdate, the child’s names, pet names, …), or by trying everything (from a, b, c to 10 characters passwords with special characters), it is possible to try many combinations. As for the brute force method, the only way to be safe is to use a long random password with special characters.

MD5 dictionary tables are big. It is so widely used that huge databases like this have been created over the years. If your password is inside (and there is a good chance if you have a “short” password), your accounts are not safe at all.

MD5 has collisions, which leads to collision attacks. The MD5 algorithm has also proven issues within its cryptographic method. A collision is when two words have the same hash generated. Safe algorithms have a good collision resistance. That’s to say that you have low chances to get the same hash for different words. But MD5 has a low collision resistance.

MD5 is also comparatively slow when compared to other algorithms like the SHA Algorithm.

What is our advice?

Considering its flaws and advantages, it is neither recommended nor useful for advanced encryption applications. Using MD5 to encrypt important data is not recommended at all. Rather, we recommend Bcrypt when encrypting crucial data and passwords. Additionally, in order to improve your database security, you can use salt while encrypting passwords.
