FIPS Standard
SP 800-67 Rev. 2 (deprecated)
Deprecation Date

Known Vulnerabilities
- Sweet32 birthday attack (64-bit block)
- Grover's algorithm
- Meet-in-the-middle (effective 112-bit)
Notes
Deprecated by NIST after 2023. 64-bit block size makes it vulnerable to Sweet32. Effective security of ~112 bits classically, ~56 bits post-Grover. Do not use.
