MD5 Hash Generator Online
Generate MD5 hashes quickly in your browser. While MD5 is no longer recommended for cryptographic security, it remains widely used for checksums and non-security hash needs.
Hash Generator
Generate SHA-1, SHA-256, SHA-384, and SHA-512 hashes using the Web Crypto API.
What is MD5?
MD5 (Message Digest Algorithm 5) produces a 128-bit (16-byte) hash, displayed as a 32-character hexadecimal string. Designed by Ronald Rivest in 1991, MD5 was widely used for decades but is now considered cryptographically broken due to practical collision attacks discovered in 2004.
Should I use MD5?
For security purposes (passwords, digital signatures, certificates), do not use MD5 — use SHA-256 or SHA-512 instead. MD5 is still acceptable for non-security uses like file checksums, cache keys, deduplication, and data partitioning where collision resistance is not critical.
Frequently Asked Questions
Is MD5 secure?
No. MD5 is cryptographically broken — practical collision attacks exist. Do not use MD5 for passwords, signatures, or any security purpose. Use SHA-256 instead.
Why is MD5 still used?
MD5 remains popular for non-security uses: file checksums, cache keys, data deduplication, and legacy system compatibility. It is fast and produces compact 32-character hashes.
