Thread: Agilebits 1Password support and Design Flaw?
Post: RE: Agilebits 1Password support and Design Flaw?
| atom, you are doing the AES decryption on GPU? I guess you are using the table-based approach (such as what OpenSSL does and not what the AES sample from AMD APP SDK does). Do you store the expanded k... |

Thread: Breaking Samsung Android Passwords/PIN
Post: RE: Breaking Samsung Android Passwords/PIN
| Yes, salted SHA1/MD5 is generic, iterated sha1 is apparently Samsung-specific. Yes, it makes no sense to attack sha1 if you can attack md5. BTW you would be surprised how weak the pattern lock is, it ... |
