The MD5 Hash Generator computes the MD5 message digest of your input text, producing a 128-bit (32-character hexadecimal) hash value. MD5 is a one-way hash function — you can generate a hash from text, but you cannot reverse it to recover the original text.

MD5 hashes are commonly used for file integrity verification (checksums), generating unique identifiers, and data deduplication. While MD5 is no longer recommended for cryptographic security due to known collision vulnerabilities, it remains widely used for non-security checksums and legacy system compatibility.

Hash generation runs entirely in your browser using the js-md5 library. Your input text is never sent to any server, making this tool safe for generating hashes of sensitive content.

How to Use MD5 Hash Generator

  1. 1Type or paste your text into the input area.
  2. 2The MD5 hash is computed and displayed instantly.
  3. 3The hash is a 32-character hexadecimal string.
  4. 4Click Copy to copy the MD5 hash to your clipboard.

Frequently Asked Questions

What is an MD5 hash?▾
MD5 (Message Digest Algorithm 5) is a hash function that produces a 128-bit (32-character hex) digest from any input. It is a one-way function: the same input always produces the same hash, but you cannot reverse the hash to find the original input.
Is MD5 secure for passwords?▾
No. MD5 is not recommended for password hashing or cryptographic security. Known collision attacks make it possible to find different inputs with the same MD5 hash. Use bcrypt, scrypt, or Argon2 for password hashing instead.
What is MD5 still used for?▾
MD5 remains useful for non-security purposes like file integrity checks (verifying downloads), data deduplication, cache keys, and generating unique identifiers where collision resistance is not critical.
Can I decode an MD5 hash?▾
No. MD5 is a one-way hash function. You cannot reverse an MD5 hash to recover the original text. This tool only generates hashes, not decodes them.
