Our Online MD5 Hash Generator is a powerful and convenient tool for creating MD5 checksums from any text string. MD5 (Message-Digest Algorithm 5) is a widely used cryptographic hash function that generates a 128-bit (32-character) hexadecimal number. While no longer recommended for security purposes like password storage due to known vulnerabilities, MD5 remains highly useful for verifying file integrity, creating checksums, and other non-cryptographic applications.
  1. Simply type or paste your text into the input field.
  2. The tool instantly calculates and displays the MD5 hash in four different formats: 32-bit lowercase, 32-bit uppercase, 16-bit lowercase, and 16-bit uppercase.
  3. Click the 'Copy' button next to any format to copy the hash to your clipboard for your use.

What is an MD5 Hash used for?

MD5 hashes are primarily used to verify data integrity. By comparing the MD5 hash of a source file with the hash of the destination file, you can ensure that the file has not been altered or corrupted during transfer. It's also used in digital forensics and e-discovery.

What is the difference between 16-bit and 32-bit MD5?

A standard MD5 hash is 32 characters long (128 bits). The 16-bit version is a shortened version, derived from the middle 16 characters (from the 9th to the 24th character) of the 32-bit hash. While less unique, it's sometimes used where a shorter hash is required.

Can MD5 be reversed or decrypted?

No, MD5 is a one-way hashing algorithm. It is computationally infeasible to reverse the process and obtain the original input text from the hash. However, due to 'hash collisions' (different inputs producing the same hash), it is not considered secure for applications like password storage anymore.

MD5

MD5 (Message-Digest Algorithm 5) is a widely used cryptographic hash function that produces a 128-bit (16-byte) hash value, typically expressed as a 32-character hexadecimal number. It was designed to be used as a checksum to verify data integrity.
