Frequently Asked Questions
Is MD5 secure for password storage?
No. MD5 is vulnerable to collision attacks and is too fast for secure password hashing. For passwords, use modern PBKDF2, Argon2, or bcrypt.
Why was MD5 broken by cryptographers?
Researchers discovered practical collision vulnerabilities where two completely distinct files or inputs produce the identical 128-bit MD5 checksum.
When is it still acceptable to use MD5?
MD5 is still widely used for non-cryptographic checksum verification, legacy system validation, and verifying ISO/disk image download integrity when provided by the vendor.
