Frequently Asked Questions
Should I use MD5 or SHA-256 for security purposes?
MD5 and SHA-1 are broken for security use — they are vulnerable to collision attacks. Use SHA-256 or SHA-512 for any security-sensitive hashing. MD5 is still fine for non-security checksums.
Are hashes reversible?
No. Cryptographic hash functions are one-way — you cannot recover the original input from the hash. However, short or common inputs can be looked up in precomputed rainbow tables.
