What is MD5 Hash?

MD5 (Message-Digest 5) algorithm is a widely used cryptographic hash function.

The MD5 hash algorithm always produces the same 128-bit hash output for the same given input. The input string can be up to 256 characters in length. An MD5 hash output is composed of 32 hexadecimal characters.

Where is MD5 Hash used?

The MD5 hashes were commonly used for storing passwords, credit card numbers or other sensitive data in database. Now, MD5 hashes are used to ensure the data integrity of files.

Is MD5 Hash secure?

MD5 Hash function is irreversible, you can't retrieve the original string.

Md5 is no longer considered as a secure way to store passwords. Collisions were found, and decrypt is becoming more and more easy due to the increasing calculation power.
