Multi-line MD5 hash generator, MD5 encryption

What is this multi-line MD5 hash generator?

It is a free online multi-line MD5 hash generator that was made by the 'PU Tools' developer team. The number of uses is unlimited without any registration requirement.

It will use your text items, where each item is on a separate line as multiple inputs which are used to encrypt into multiple MD5 hash results at once.

It does allow your maximum input items that are up to 50,000 each time. If your requirements are larger, you can split them and use this tool multiple times.

If your items have one or multiple empty lines, and you don't want this hash generator to encrypt them, please check the 'Remove empty lines' option.

It's fair and treats an empty character as a single character (*).

If you don't enter anything, it means you want to enter an empty character. Of course, we respect your decision.

The empty character in MD5 is 'd41d8cd98f00b204e9800998ecf8427e'.

To find the corresponding MD5 hash, please enter your text into the form above.

Below are the test vectors of MD5 encryption:

Explanation of the point (*):

As a programmer, I usually have to work with characters in the command line, database, and the user's input includes alphabets, numbers and other special characters.

So, all the characters are very important to me. I have to work with them seriously to avoid errors occurring. That's why this tool is the same as me, and it doesn't have the right to ignore any type of character.

Thus, if you want it to encrypt an empty character. Just leave the input box empty or give an empty line in your list of items.

About the MD5 encryption.

MD5 is an acronym for 'Message Digest Algorithm 5'. Ronald Rivest designed it in 1991 as an improvement over MD4.

It is a one-way hashing algorithm. There isn't any direct method for its decryption.

It is a widely used cryptographic hash function that produces a 128-bit (16-byte) hash value. There are 32 hexadecimal characters in an MD5 hash.

It can be used as a fingerprint or encryption function for a file, and it is frequently used to encrypt database passwords. Not only that, but can also be used as a checksum to ensure that data integrity is protected from inadvertent corruption following a transmission.

MD5 was previously commonly used to hash passwords before storing them in databases. However, due to security vulnerabilities, this method is no longer recommended.

For programmers, if you want to increase the security of MD5, you can add salt to the beginning or end of the value you want to encrypt. The stronger the salt you add, the more secure your output will be. Example of a strong salt: 6k#N3^1bT0J8.
