Does glibc2 version of the crypt function still use DES for alternative hashing methods? @VilhelmGray yep. MD5(pass+salt) will just be an array of bytes, e.g. uint8_t arr[20]; (adjust 20 for bits/8) and the encoded version will be too, just modified so that each byte is printable. Technically, you could just store it in the file unprintable (what you might call a binary file) but Unix configuration has always traditionally used readable text files. |

Does glibc2 version of the crypt function still use DES for alternative hashing methods? @VilhelmGray I imagine they encoded the hash value in a range of printable characters. It looks like BASE64 but I could be wrong. Either way, encoding in just 0-9,A-F requires two bytes per byte of actual data and is therefore quite expensive to use. |

Designing a Sandbox for Windows @Maarten I had a go at piecing together how it works. It was a while ago and is not by any means complete, however: security.stackexchange.com/questions/3861/… |

Designing a Sandbox for Windows Just for your info, in the future it might. VMWare currently let you emulate VT-x, so you can run their ESX product on workstation. It's slow as hell, but conceivable you could do it. This will probably improve in the future... |
