Which password storage technique is considered most secure against rainbow table attacks?

Password storage security comparison: Plaintext: Never acceptable — immediate compromise on breach. Base64: Only encoding, not encryption/hashing — trivially reversible. MD5: Cryptographic hash but broken — fast, collision-vulnerable, rainbow table attacks. SHA-1: Also deprecated — faster than needed for passwords, vulnerable to rainbow tables. Bcrypt with Salt: most secure for password storage:   - SALT: Random unique value added to each password before hashing.     Salt makes rainbow tables useless (each password has unique hash).   - BCRYPT: Adaptive hash function — computationally slow by design.     Work factor can be increased as hardware gets faster.
