How it works
MD5 processes input bytes in 512-bit (64-byte) blocks through four rounds of 16 operations each, using nonlinear functions, additive constants, and left-rotate shifts. The result is a fixed 128-bit (16-byte) digest, typically shown as a 32-character hexadecimal string.
Frequently Asked Questions
Is MD5 secure for passwords or sensitive data?
No. MD5 is cryptographically broken — collision attacks are practical and fast. Do not use it for passwords, digital signatures, or security tokens. Use SHA-256, SHA-3, or a dedicated password hasher like bcrypt or Argon2 instead.
Can I recover the original text from an MD5 hash?
No. MD5 is a one-way function — it maps arbitrary input to a fixed 128-bit output, and reversing it is computationally infeasible. You can only compare hashes or look up common ones in rainbow tables.
