Generate MD5 Hash
What is the MD5 generator?
MD5 is an algorithm function that calculates a hash for a text. When you need to store a secret or check if a text wasn't modified, you must do a checksum and keep the hash result. In the following verification, we compare the hashes.
MD5 is considered the most popular digest function and is widely used. This can also be considered a con because many hackers have the hash for billions of passwords. Suppose a website uses the MD5 algorithm to store passwords, and their database is compromised. In that case, most of the users are in serious danger because their password was revealed
Yahoo caused one of the most significant data breaches regarding MD5. The company used the MD5 function to store passwords, but their database was compromised, and billions of accounts were hacked. The conclusion is not to used MD5 to store passwords.
Frequently asked questions
- What are the steps for MD5 Hasher?
The steps are:
- Enter your text
- Optional: Select the checkbox to include salt and specify the salt or use the default value
- Select button
- Optional: Register to use our free API to get using REST the hash
- What does MD5 stand for?
It stands for Message Digest 5 because it's the fifth version that was accepted for this function.
- Is it safe to use?
MD5 is fast and simple and used for many purposes, but don't use it for savings secrets or verifying integrity because it has many collision issues. Use an algorithm like SHA256 for storing passwords.
- What's the difference between hashing and encryption?
The most significant is that hashing is a one-way function and encryption can be two ways. This means that from the result of hashing, you cannot get the initial value, so it's irreversible. Encryption can be decrypted.
That's why the passwords must be hashed and not encrypted, because someone can decrypt that password.
- What is salt?
The salt is a sequence of random characters that are combined with the initial password and the result is hashed. This is a more secure way to store passwords because hackers cannot use the dictionary method to crack the hashes.
For example, if a user's password is 123456, using a random salt will secure his passwords from a dictionary attack because password hash is different using salt than without salt.
- Can someone decrypt it?
No, this cryptographic function can't be decrypted, but there are many sources where you can find for words their hashes. Based on dictionaries, someone can know for which word is the encryption.
- Is it free?
Yes, it's 100% free to use.
- There is an API available?
Yes, register to get an API key and read the documentation.
