Thanks,

Do you have the files? I could take a look at it. I'm pretty sure it's encrypted against one password for all of it. Triple DES.

In Windows, Chrome uses the Data Protection API (DPAPI) to Triple DES using your Windows user's password. This means that every other program running under your Windows user is able to decrypt the login data. In fact, that's how tools like ChromePass and ChromePasswordDecryptor work. They only decrypt the file and reveal the passwords only if you run them on the same system that encrypted the file (or, perhaps, provide the victim's Windows password).

If the attacker was only able to acquire the Login Data file (for example, you had the file on your memory stick and it was stolen/lost), then your login data are protected as strongly as your Windows password is.

I read that one too. I'm not sure if the file itself is encrypted or if each password is encrypted with DES individually. If the whole file is encrypted with DES, then i wont be able to crack it with any tools i have. If its just the passwords in the file, i should be able to feed them into something as text and try to crack them. Even oclHashcat supports some forms of DES.

Well, if you post a link to the login.data people could have a go at it.
