All Hash Generator (MD, SHA, CRC & more)

No — MD5, along with MD2, MD4 and SHA-1, is cryptographically broken and unsuitable for security purposes such as signatures or password storage; they remain useful only for non-security checksums like file-integrity verification or cache keys.

No — none of the algorithms here are designed for password storage because they are all fast by design, which makes brute-forcing stolen hashes cheap; use a slow, tunable algorithm like bcrypt instead.

MD6 was never formally standardized and has no reliable JavaScript implementation, and RIPEMD-160 is the only member of the RIPEMD family with a well-tested implementation available — RIPEMD-128, RIPEMD-256 and RIPEMD-320 are rarely used today and aren’t reliably supported in the JavaScript ecosystem.

NTLM is the password hash format used internally by Windows, and it is computed exactly like MD4 except the input text is encoded as UTF-16LE instead of UTF-8 before hashing.

SHA-256 is the standard choice for file integrity today, since it has no known practical collision attacks and is what most modern checksums, such as package managers and download mirrors, publish; CRC32 is faster but is meant to catch accidental corruption, not intentional tampering.
