Do MD5's weaknesses affect Oplop? @fgrieu if the master password has over 100 bits of entropy (e.g. a 20-character base64 string generated by flipping a coin), can it be cracked? |

Do MD5's weaknesses affect Oplop? @CodesInChaos it guarantees that Oplop complies with websites that require passwords to contain numerals. |

Is SHA-256 secure as a CTR block cipher? I guess the testing aspect is the most important since no one wants to be solely responsible for the potential failure of a system -- if SHA-256 in CTR fails, its implementer is held accountable; if AES-256 fails, everyone is screwed. Though you say a $2^{256}$-block known message can enable key recovery with an effort of 1... how is that possible? |

What is the most secure hand cipher? 1. Purely academic interest; 2. For the rest of the forseeable future, there will be situations in which people are denied access to private computers. |

What is the most secure hand cipher? Thanks for the link. I'll give the RC4 implementation mentioned by Ilmari a try, although it seems a bit too cumbersome to meet my criterion of a hand cipher, especially if it is implemented without the pitfalls of WEP and other broken systems. I'm also interested in other systems that weren't mentioned. |
